In-District • Total District Acreage = 154,000 acres • Total Irrigated Acreage = 115,000 acres • Average Farm Size = 49 acres • Small Family Farms • Over 50 Types of Crops • Estimated Crop Value = $221M • Direct Agriculture Impact = 1/3 of
Merced Economy
• San Joaquin Valley Continues to be Among Hardest Hit Regions in Nation from Recession
• Especially True in Merced • Foreclosure and Unemployment Rates Within
Top 10 for Entire Country • More Than a Fourth of Our Residents Live
Below Poverty Level – Twice That of Rest of State
• Half Per Capita and Half Household Income as Rest of State

SED Analysis • Devastating Impact on Local
Economy • Approximately $23.5 Million Annual
Losses to Communities that Depend on Merced ID
• Could See Direct Loss of 160 Jobs • Indirect Loss Even Higher

Economic Impacts

District/Regional Economics • Loss of Revenue
• Reduced Surface Water Sales • Reduced Hydropower Revenue • Reduced Customer Base
• Impacts Operations and Maintenance • Stranded Capital Costs • Water Removed Has a Value
• Communities Required to Reinvest in a Different Water System
• Significant Cost to Salvage What is Left

Historical groundwater pumping 7,000 cfs to
100,000 + AF supplemented by private pumping
MID owns and operates 185 active wells in years of surface water shortage
Merced ID – A Conjunctive Use District
Groundwater Impacts
Conjunctive Use • Coordinated Use of Surface Water and
Groundwater • Actively Managing Underground Aquifer as
Reservoir/Bank • During Normal and Wet Years Surface Water is Applied
to Maximum Acreage Possible • Minimizes Need for Groundwater Pumping • Recharging, or “Banking,” Surface Water in the Aquifer • Withdrawals from “Bank” are Made During Years of
Limited Surface Water Supply

• Draft SED States • MID Capacity for Pumping Groundwater =

• Due to Dropping Groundwater Levels, Capacity = 100,000 AF
• Aquifer is Already Stressed and Proposed Action Will Drive More People to Aquifer, Further Reducing Yield

•Recreational Impacts at Lake McClure • Recreation Facilities Rendered High and
Dry • Recreation Driven in Large Part by Lake
Levels • Severely Limits Shoreline Access • Reduced Visitation
Average Annual Reduction in Cold Water Storage at End of June of 100,000 AF
Cold Water Pool Impacts
Higher Release Temperatures from New Exchequer Reservoir when Fall-Run Chinook Return to Spawn
Cold Water Pool Impacts
FERC Study Results (Current Conditions) • Spawning
• Spawning Timing As Expected • Egg Viability is High in Merced River
• Rearing • Habitat Availability Generally Exceeds 80% Through May • Fry, Pre-smolt And Smolt Abundance Consistent With
Escapement
• Outmigration • SURVIVING OUTMIGRATION IS WELL BELOW EXPECTED
UNDER EXISTING FLOWS AND TEMPERATURES
Merced River Chinook Salmon Impacts
• Spawning Impacts • Temperatures During Spawning Would Increase • Delay Spawning and Timing of Subsequent Life
Stages • Decrease Survival
• Rearing Impacts • Rearing Habitat Availability Will Not Increase
and Potentially Decrease With Warmer Temperatures
• Outmigration Impacts • Timing of Outmigration Will Be Delayed • Decreasing Survival Potential and Production
Merced River Chinook Salmon Impacts
•Draft Flow Objective Can Adversely Affect Viability of Merced River Chinook Salmon
•Conflicts with Stated Purpose •Request SWRCB Study and Disclose
These Impacts and Provide Rational on Why Benefits of Spring Releases Outweigh These Impacts
Merced River Chinook Salmon Impacts
Merced ID Voices Strong Opposition to Draft SED • Unravel Decades of Sustainable Regional
Conjunctive Use and Regional Water Supply Collaboration
• Results in Over-Drafting of Groundwater Basin • Cost Jobs, Economically Devastates an Already
Struggling Region and Destroys a Way of Life for Thousands of Small Family Farmers
• Presents Unilateral Demands Without Quantifying Benefit or Goal to be Achieved
31
Conclusion
Merced Irrigation District Requests • Pursue Comprehensive Solution
Consistent with Delta's Co-equal Goals • Prioritize Non-Flow Measures Before
Demanding Flow Increases that Threaten Economic Vitality of Already Distressed Counties, Cities, and Small Family Farms
32
Conclusion
