Sportfishing Notes
Rainbow Trout
•Spinners, bait (powerbait &
nightcrawlers), and flies are all
productive tools. Fishing is
typically best April-June and
during the winter.
•At times the rainbows are so
aggressive they often deep
hook themselves while
attacking bait. Anglers who
encounter a deep hooked trout
are highly encouraged to keep
these fish. Trout hooked in
this fashion will not survive.
•More than 40,000 ten inch rainbow
trout are stocked annually to
accommodate the heavy angling
pressure. Trout are primarily
stocked in Sandpiper, Mallard, and
Coot Ponds. Trout are strategically
stocked in the spring and fall when
cooler water temperatures prevail
and to increase ice fishing
opportunities.
Left: The summary of the 2017 survey for Sandpiper Pond. This pond is primarily managed for 10-inch trout which are heavily stocked in the spring and late fall (ice angling). Roughly 20,000 catchable trout are stocked annually. Besides trout, good numbers of catfish and bass (up to 21”) were present. Bluegill and crappie are present but are rather small.
Sandpiper Pond.
Left: The summary of the 2016 survey for Mallard Pond. Mallard is primarily managed for 10-inch trout; heavily stocked in the spring and late fall (ice angling). Roughly 6,000 catchable trout are stocked annually. Trout stocking at the park typically does not occur between May 15 – September 15 because of warm water temperatures.
Pelican Pond – all fish were eliminated September, 2010 (94% carp). Later flood waters breached the pond destroying the aeration system and re-introducing common carp. Predators (pike, walleye, and saugeye) have been stocked to reduce the carp, suckers, and shad. These predator populations have started to take hold and large Northern Pike can be caught.

Bald Eagle Pond – No bait fishing, flies and lures only. Catch and release only for bass.

Bald Eagle Pond is managed as a trophy largemouth bass fishery. All bass must be returned to the water immediately. Bait fishing is not permitted in this pond. To help bass growth rates, this pond also receives thousands of bluegill. Anglers may keep species other than bass (general regulations apply), provided such fish are caught using artificial flies or lures.
Coot Pond has quality bass and receives trout during the spring and fall. Saugeye and walleye were stocked for the first time in June 2010 and during each subsequent year. Good number of channel catfish are in Coot Pond as well, providing for a diverse fishing opportunity. Rainbow trout are stocked seasonally into Coot with ice fishing being quite good.
Pintail Pond: Northern pike have beenstocked in Pintail to consume overabundantcarp, shad, and stunted bluegill.

Blue Heron – Now Open! Wakeless boating will be allowed. Previously stocked with black crappie, redear sunfish, channel catfish, saugeye, and largemouth bass.
Left: The summary of the 2017 survey for Blue Heron Reservoir (4 gillnets and boat electrofishing). Management will focus on angling for bass, crappie, and walleye. Crappie populations have not taken hold due to competition with prolific gizzard shad. However, this base level of bait fish provides walleye and largemouth bass with good resources to sustain healthy populations that provide good fishing opportunity.
