President’s ReportLake levels in the Spring of 2016What an unusual winter, especially considering that Eagle Lake did not freeze over until the middle of January and the ice went out on April 2nd. This must have been one of the shortest ice on-off periods ever. Compared to the past few years, you likely noticed that the lake water level was quite reasonable this spring. This was perhaps due to the limited snow-pack and spring rain, but water levels were probably also influenced by our access to the beaver dam in front of the CPR track culvert and our ability to keep this dam cleared in the late fall and early winter last year. Efforts to clear the dam resulted in an active flow at Eagle Creek all spring and the lake level dropped to near normal levels in early to mid-May. For this we must

thank Bill White and Mike Day who repeatedly cleared the beaver dam at the CPR track culvert in the late fall to early winter. As well, Bill White monitored beaver dams downstream and trapped beaver in the upper part of Eagle Creek this winter, which contributed to maintaining flow in Eagle Creek. We appreciate his services.

The lake water level is being regularly checked at the control dam on Eagle Creek by MNRF staff from Kingston. In fact, logs were added at the control dam on May 19th in order to maintain an ideal level for the summer. The difference in spring lake levels between 2015 and 2016 is evident in Figure 1.

Whether this trend persists will only become apparent with water level monitoring for the next few years.

President’s Report, continued telescope and enjoy the dark skies. The next event is planned for June 4 when there is no moonlight which will make it perfect (if there is no cloud cover of course) to view Saturn, Mars, Jupiter, asteroids and deep sky objects. The event is free and open to all and there will be amateur astronomers available who provide context to what you see. There are also events July 1 and 2 (No Moon. Saturn and Deep Sky clusters, Nebulae, Galaxies visible) and July 30 and 31 (Deep Sky, Mercury, Venus, Saturn and Mars visible).

Algonquin Land ClaimAs reported in the Pembroke Daily Observer (March 17th and April 28th), the results of the agreement-in-principle (AIP) ratification vote, held from Feb. 29 to March 7, showed that 90 per cent of the ballots cast were in favour of proceeding with negotiations towards the terms of a final agreement between the Algonquin First Nation and the federal government and the province of Ontario. Members of the Algonquin First Nation have overwhelmingly endorsed the AIP that paves the way for the negotiation of an historic land claim. However, the Pikwakanagan First Nation based in Golden Lake voted against the agreement in a separate, parallel referendum. In that plebiscite, 243 Pikwakanagan members voted against the AIP, while 87 votes were cast in favour of it. The Pikwakanagan situation is currently being sorted out and the AIP process is on hold until this has occurred.

Lot Development on Highly-sensitive Lake Trout LakesThrough the efforts of Central

Frontenac Township (CFT) staff, including a workshop on this topic in September 2013, we thought we had sorted out the guidelines for lot development of the four highly-sensitive Lake Trout lakes in the township, which includes Eagle Lake. Now, however, such development will likely become more stringent if the guidelines established in the now Official Plan for the County of Frontenac (http://www.frontenaccounty.ca/en/corporate/resources/County-of-Frontenac-Official-Plan---Consolidate-Copy.pdf) is adopted for the now overdue Official Plan for CFT. The relevant criteria for the county (page 67) now reads:

7.1.4.4.1 Lake Trout Lakes Policies · New lot creation shall not be allowed within 300 metres of at capacity lake trout lakes located in Frontenac County. The list of such designated lakes are identified on Appendix “1B” and listed in Appendix “2” and shall be included in Local Official Plans.

Currently in CFT, new lot creation on a highly-sensitive Lake Trout lake requires 6.75 acres (2.73 ha) based on the currently mandated 91 metres of shoreline and minimum depth of 300 metres (984 feet) for the septic system. Under the new guidelines above, locating the cottage/house beyond 300 metres on a lake-front property would require a lot size considerably greater than 6.75 acres. In the current zoning bylaw, the main building must be set back at least 30 metres (98.4 feet) from the shoreline. In the County policy, it would appear that the main building would be situated beyond 300 metres (984 feet). A long way to the shoreline!

FOCA Lake Networking Group SeminarLearn what you need to know to protect the family cottage for the future through this popular cottage succession seminar “Keeping the Family in the Family Cottage.” The session is hosted by estate lawyer, Peter Lilico, and contains valuable information such as: uwhy to start the conversation NOWupaying the Capital Gains Taxumanaging responsibilities and

expenses to keep the cottage going once the next generation is in place

The seminar will be held at the Perth Legion Hall, 26 Beckwith Street, East, Sunday, August, 14, 2016 from 12:30 to 2:30 p.m. NOTE: This event is FREE to members of FOCA and the Lake Networking Group, or $10 at the door for non-members. Please pre-register with FOCA (mention that you are a member of a lake association that is affiliated with the Lake Networking Group to avoid the fee) to secure your space by email [email protected] or 705-749-3622.

Astronomy in North Frontenac Did you know that North Frontenac has the darkest skies in southern Ontario? Therefore, the Dark Sky Preserve, which is located at 5816 Road 506 just south of Plevna, is one of the best places for stargazing in the province. The North Frontenac Dark Sky Preserve just released their 2016 schedule of events (http://www.northfrontenac.com/dark-sky-preserve.html). The Observation Pad is a public space with amenities, including parking, washroom, electrical service and the concrete pad, where anyone can setup their

Possible WaterfrontLot LimitationsPlanned clarifications to South Frontenac Township’s zoning bylaw proposed by Lindsay Mills, the township planner and deputy clerk, have upset some residents, who see them as infringing on property owners’ rights. Another controversial action is occurring with South Frontenac Township proposing changes to its Comprehensive Zoning Bylaw, Section 5.10.2, to clarify what is allowed when rebuilding or renovating within 30 metres of the waterfront. The proposed new wording of this section includes the following:

“Where a building has been erected prior to the date of passing of this Bylaw on an existing lot and said building has less than the minimum 30 metre (98.4 ft.) setback from the highwater mark of a waterbody or watercourse, then said building may be repaired, renovated or strengthened to a safe condition provided there is no enlargement of the gross floor area or increase in height. Reconstruction of the building is prohibited. In addition, no living space shall be added below grade to any existing building or structure. For the purposes of interpreting section 5.10.2, once the walls of an existing structure within the minimum 30 metre setback have been removed, the land is deemed to be vacant and the structure may not be reconstructed within the 30 metre setback.”

Another change would remove a clause in the zoning bylaw that permits a building destroyed by “fire, lightning, explosion, tempest, flood or act of God” to be rebuilt in the same location. Instead at a meeting on April 26th, the South Frontenac Township planner said the township would consider each property on a case-by-case basis (reference 1). At the second council meeting on this topic on May 10, cottagers were again well represented

and some suggested that “these proposed changes would lower values of lakeshore properties with nonconforming structures, possibly even make them unsaleable” (reference 2). Mayor Vandewal then brought a notice of motion that “If a property is destroyed by fire or other act of God the owner need only go to the building department and apply to rebuild on that footprint.” Council’s decision on Mills’ proposed ‘housekeeping amendments’ has been postponed until the June 7 Council meeting.

These zoning by-law considerations do not apply to our township. It should be appreciated, however, that if such changes are implemented in South Frontenac Township, it would not be long before they could be proposed locally.

Canada 150

The March 16th issue of the Frontenac News reported that Bill Bowick is chairing a committee planning local activities celebrating the country’s 150 birthday. In the fall newsletter, we will invite Bill to outline that plan that has been developed to that stage. Perhaps ELPOA should participate in these local arrangements by planning some form of party and other activities at the lake in the summer of 2017.

Boat Safety EquipmentOne of our members has arranged a new free service for Eagle Lake residents. See page 6 for a way to ensure adequate marine safety equipment and avoid potential OPP fines.

Algae and Aquatic Plant Research PublicationSignificant algal blooms of any type are an annoyance that everyone wants to avoid. As a result of the research grant focusing on excessive algae and aquatic plants reported on page 10, an educational booklet on this topic and the benefits of a healthy algae community, as well as the disadvantages of algae overgrowth, should be required reading for lakeshore property owners. It is entitled “Algae and Aquatic Plant Educational Manual; People, Aquatic Plants and Healthy Lakes: Finding the Balance in Eastern Ontario Project” and can be downloaded at: http://www.rvca.ca/PDF/Algae%20Manual%20Concise.pdf

The title, Fifty Years of Outstanding Service, speaks to the conservation efforts by the Rideau Valley Conservation Authority (RVCA) for our watershed since official formation on March 31, 1996.

When the Province of Ontario passed the Conservation Authority Act in 1946, it was responding to “growing concerns that land uses and deforestation were contributing to deteriorating water quality, flooding and soil erosion” and the development of conservation units was a significant approach to addressing local environmental concerns.

To appreciate some of what has been accomplished in the past 50 years in our particular watershed, check out the impressive list of successes—as well as the accompanying poster—by RVCA and its local partners:

- 9 million dollars of grants distributed to landowners undertaking stewardship projects

- 5.7 million trees planted on private lands equaling 24 square kilometres of new forest

- 2,800 hectares of sensitive lands acquired and protected

- 186,450 water quality samples taken- 16.5 kilometres of shorelines

naturalized and buffers planted- 9,650 kilometres of streams

surveyed- 17,500 butternut seedlings planted- 29,000 volunteer hours invested in

watershed health- 42 kilometres of trails created

for outdoor recreation at local conservation areas

- 23,700 Planning Act application reviews completed

- 6,475 permits processed under Section 28 of the Conservation Authorities Act

- 250 Environmental Assessment Act reviews

- 4.5 million dollars fundraised by the Rideau Valley Conservation Foundation

- 62,000 visitors annually to our conservation areas including 10,000 students

- 14,950 septic approvals issued, plus 3,600 re-inspections along lakes

Fortunately, Eagle Lake is part of the watershed directly influenced and serviced by RVCA. Their conservation region is quite extensive, with the total length of the longest part about 180 kilometres, and is made up of a number of subwatersheds. The westerly extent, the Tay River subwatershed, which includes Eagle Lake, alone extends for approximately 95 kilometers and covers an area of about 850 square kilometres (328 square miles). So this conservation region is quite an environmental challenge and responsibility.

As one part of the RVCA environmentally focused mandate, they initiated water quality assessment on 39 of the 46 major lakes in their watershed region in 2001. As a result of this Watershed Watch Program, we have accumulated data on local water quality since 2002 that would not otherwise have been available. Such valuable information has been used in a number of positive ways at Eagle Lake, as well as providing comforting assurance of the high

quality of the lake water. We continue to interact with RVCA in a profitable fashion and have greatly benefited from their expertise and friendly cooperation.

Many of our Eagle Lake residents are likely unaware that RVCA has a vested interest in this lake. Some years ago, a property was bequeathed initially to Nature Conservancy of Canada and subsequently transferred to RVCA. In addition, they own a parcel of land adjacent to the Bobs Lake Road that borders on a portion of Eagle Creek. All the more reason to interact with this outstanding conservation authority to both protect the many outstanding features of Eagle Lake and assist RVCA in maintaining a healthy watershed.

Commenting on the 50th anniversary, RVCA General Manager Sommer Casgrain-Robertson noted: “The work done has laid a strong foundation for a healthy and sustainable future. But there is lots left to do and we look forward to working with our many partners and landowners to achieve our goals for a healthy watershed for all.”

For over ten years ELPOA has had complete coverage of Eagle Lake for our annual report to the Canadian Lakes Loon Survey sponsored by Bird Studies Canada. Now that the Krotkovs are no longer able to survey the central section of Eagle Lake (section 2 on the map) we are looking for a volunteer interested in participating in this project.

Canadian Lakes Loon Survey participants track Common Loon reproductive success by monitoring chick hatch and survival. Participants dedicate at least three dates, visiting their area once in June (to see if loon pairs are on territory), once in July (to see if chicks hatch) and once in August (to see if chicks survive long enough to fledge).

Contact Olivia Culver at [email protected] for more information about participating in this project.

Recreational Vessel Courtesy Checks on Eagle Lakeby Bill Corcoran, President of Kingston CPS & Stephen Duggan

The Kingston Power and Sail (KPS), as part of the Canadian Power and Sail Squadrons (CPS-ECP), offers a complimentary (free!) Recreational Vessel Courtesy Check of the required safety equipment for your boat every year. The safety requirements and criteria for the check are published by Transport Canada’s Office of Boating Safety in the Safe Boating Guide (http://www.tc.gc.ca/media/documents/marinesafety/TP-511e.pdf). This informative and easy to follow guide contains lots of helpful information and outlines the minimum safety requirements for all boats, from paddleboards to motor yachts, operating in Canadian waters.

KPS will be offering checks in the area from Napanee to Rockport and north to Sharbot Lake, Westport, Portland and Charleston Lake this Spring and early Summer. Stephen Duggan, an Eagle Lake resident (he can be reached at [email protected]) has organized this service for Eagle Lake boaters at Parham Landing on Sunday, June 26, 2016 from 10 a.m. To 3 p.m..

The check requires a visit to your boat and takes about 15 to 30 minutes to complete, depending on the size of the boat. If you have the equipment as outlined in the Safe Boating Guide aboard, KPS will issue a 2016 decal that can be displayed on you boat. Authorities (RCMP, OPP, CBSA) will be able to see that you have had a courtesy check this year and may give you a pass. The check is anonymous; only

generic information (boat size and type, complete or uncompleted) is provided to Transport Canada for review.

The foremost purpose of the program is your safety and the safety of everyone in or on the water. Law enforcement offers hefty fines ($200 per offense) for each piece of missing safety equipment, that can tally in the thousands of dollars. Sharbot Lake Marina is offering a 10% discount on the cost of deficient items disclosed by the inspection.

Down Memory Lane: The Tichbourne End of Eagle LakeMike Clobridge

For the past 4 or 5 years, I have been promising to write a story that captures the nostalgia and the history of the Tichborne end of Eagle Lake. As I write this, I apologize to anyone who I have forgotten or inaccuracies that occur. If I do miss you, please stop and correct me at the next AGM.

I have been on the lake for seventy years, having come from England with my mom, who was a war bride. My father, Russell Clobridge, purchased our land in 1935 from his uncle Billy Robson for $16.00 and he threw in the back acreage for a bottle of my “Grandmother’s best” from the Tichborne Hotel.

In 1936, Dad and Levi Thompson erected the present day cottage on the point, overlooking the water. This cottage was later named Durley Chine after one of the many hotels in England Dad managed during the war. In 1946 when my mom and I arrived, I was 14 months old. However, this was not the first cottage I was taken to. No, my grandfather, Charles Clobridge, owned the cottage on Pigeon Island (currently owned by Ken and Lori Lavery). I obviously have only a few memories of the first 2 or 3 years. I do remember living in Tichborne in those early years, especially when Dad and Grandfather would hitch the team of horses up to a sled and set out to Eagle Lake to cut ice for the ice houses on the island and the one near our cottage. They cut large blocks of ice and covered them with sawdust. Yes, that was our refrigeration for the summer!

No, there was no electricity; coal oil lamps lit the cottage before we went to bed and mom had to cook on a lovely Finley cook stove…hot, especially in the summer. Our privy was a series of out houses, built far away from the cottage. Life on the lake was not especially easy for mom but we had fun!

In the 1950’s, when I was 5 years old, we moved to Chatham in southern Ontario. This did not inhibit us from going to the cottage all summer. Dad worked as a signal maintainer for the railroad and as an employee, his family could travel for free! We would leave Chatham at 4 PM and arrive at the Tichborne station at 4am the next day. Nowadays, the Tichborne station sign hangs on the front of our cottage when we are there. After walking up the tracks we would visit Grandma and Grandpa. The hotel they owned was demolished in the late 40s and replaced by a nice house. Grandma would have the breakfast on. When there was enough light we would walk over to the lake via a road that now leads to the Aird’s property. Here Dad kept a 14 foot flat bottom boat that had been built by Jim Kish on Fish Creek Rd. Dad would hit the metal gong just to alert people that we were at the landing, then row across the lake to retrieve his 1.5 hp Johnson outboard motor. After Dad cranked away on the motor and uttered a few choice words, the motor would start. He would come back to us, we would load the boat and head back over to the cottage. Then we would spend a couple of hours of unloading and settling in.

I would head to our point to sit and watch the boat activity. First, Tom Hampton would come along in his cedar strip with its 10 hp Johnson. As he passed by he would wave and yell “I’ll stop in on my way back!”. Not too long after that we would see Allan Cameron (Larry’s dad) in his cedar strip with a 10 hp Evinrude. As he passed he would display his famous smile and wave. He would also be stopping by. A little while later my prayers would be answered as I would hear the noise of oars coming up the lake. It would be Uncle Bun (Bernard Clobridge) in his green 14 ft skiff. He was a fantastic cook, so tonight’s supper would be fried chicken and roasted potatoes.

As the years passed, my brother, Stewart Clobridge and I continued the ritual of heading to the point to watch the boat activity. Then Bud Goodfellow came from the Parham end of the lake, with a larger cedar strip and a 16 hp motor.

Mom, Stew and I spent summer after summer at the cottage. Every other weekend my Dad would arrive via train. On a Friday I would lie awake listening to the trains. When I heard a train stop I knew my Dad was here. About a half hour later I could hear the motor and knew that Dad had arrived. I knew that we would have an exciting weekend of fishing.

This part of the story brings me to the late 50s and I will continue my story at a later date.

People, Aquatic Plants and Healthy Lakes – Excess Algae and Aquatic Vegetation Research Project Now Completed

Two years ago, a team from Carleton University, Rideau Valley Conservation Authority (RVCA), Mississippi Valley Conservation Authority (MVCA) and the Friends of the Tay River were funded by the Ontario Trillium Foundation to study the degree to which water quality in our regional lakes has changed over the past 150 years. This research project is now complete and a final report is in preparation.

One of the key components of the study was the analysis of sediment cores from lake bottoms of 20 lakes, 10 from RVCA and 10 from MVCA w a t e r s h e d s . Sediment cores provide a natural archive of past changes in the lake environment. Certain microscopic algae, the diatoms, which have a cell wall made of silica (glass-like), are well preserved in the lake bottom sediment. Since the many varieties of diatoms have varying preferences for nutrients and water temperature, analysis of the differing proportions of certain diatoms provide an excellent indicator of historical water quality.

Based on the proportion of diatom populations in the bottom and

top segments of sediment cores, 75 percent of the 20 lakes studied showed little to moderate change in the water quality over the 150 year time-frame. This correlates with low to moderate phosphate concentrations in this group of lakes. Analysis of the remaining five lakes revealed shifts in diatom populations indicating some nutrient enrichment and changes related to warming temperatures over the past 150 years. These results show the importance of conservation efforts to limit further changes so that local lakes remain healthy.

Eagle Lake was not included in the 20 selected lakes, but a sediment core was obtained in 2014 (Figure 1) and will eventually be analyzed as part of subsequent studies at Carleton University.

A second phase of the research project involved aquatic plant mapping, i.e., the measuring of submerged plant abundance—referred to as plant biovolume—at the shoreline of a lake. This is

accomplished by slowly motoring or canoeing along the shoreline while using an echosounder to record water depth and amounts of aquatic vegetation. The latter is eventually calculated as plant biovolume where aquatic plants growing halfway to the surface would have biovolume of 50 percent and those reaching to the surface a biovolume of 100 percent (Figure 2). Such a measure of aquatic plant abundance provides an indicator of the degree to which submerged plants become a nuisance for lake activities for swimming and boating.

Aquatic plant biovolume was recorded along the shoreline of Eagle Lake in September 2015. The density of shoreline aquatic plant growth is indicated by a colour scale (right) with blue indicating little or no aquatic plant biovolume and red indicating dense aquatic plant vegetation. The map of Eagle Lake shows limited vegetation for the majority of the shoreline (Figure 3). As might be expected of the shallowest zones of Eagle Lake, The Narrows and Curl’s Bay, increased vegetation is evident in these locations (Figure 3). A detailed comparative analysis of five shoreline zones at Eagle Lake indicated that The Narrows and Curl’s Bay (Region 2) have plant biovolume levels greater than 60 percent whereas the other four regions have biovolumes less than 40%. (Figure 4).

This summary of the research results is based on the more detailed report prepared by Dr. Jesse

Vermaire (Institute of Environmental Science, Carleton University) that is available on our website (www.elpoa.ca).

An additional product of the Ontario Trillium Foundation grant was the preparation of an educational booklet entitled “Algae and Aquatic Plant Educational Manual; People, Aquatic Plants and Healthy Lakes: Finding the Balance in Eastern Ontario Project”. This invaluable resource with information to assist in limiting algal blooms and excessive aquatic plant growth is available for download through a link on our website at www.elpoa.ca

Figure 2. Diagram explaining the concept of plant biovolume. The aquatic plant to the left reaching to the surface (dark horizontal line) has a biovolume of 100%. The plant to the right is half way to the surface (vertical line) and has a biovolume of 50%.

Figure 4. Analysis of aquatic plant biovolume by region at Eagle Lake. For the majority of the lake shoreline, plant biovolume is 20% or less, while regions 3, 4 and 5 have a small proportion in the 20 to 40% range. It is only region 2 (green bars) that has any significant plant biovolume not only in the 20 to 40% range, but also in the 40% or greater range.

Figure 3. A colour-coded aquatic vegetation map from the shoreline of Eagle Lake recorded in September 2015 as five regions (numbered between the short white lines). Judging from the coloured scale to the right, where blue represents little or no plant biovolume and red 75 to 100 percent biovolume, major regions of the shoreline at Eagle Lake have no aquatic plants (blue) with scattered regions with less than 50% biovolume (green). The only section of the lake with any significant plant biovolume is region 2, The Narrows and Curl’s Bay (yellow to red points).
