Union Valley Reservoir is a reservoir in El Dorado County, California and covers about 2,889.4 acres, reaches about 104.8 feet at its deepest point and holds roughly 266,369 acre-feet.
Union Valley Reservoir is big water, and a useful pattern in one arm may not carry to the far end of the lake. Deep water at Union Valley Reservoir gives fish room to move away from shore as summer heat and bright light build.
What Makes Union Valley Reservoir Different
This water is a high Sierra water-supply lake with kokanee, trout, smallmouth bass, granite points, timber, and broad open water; add vibration in stained water.
Find kokanee before setting a trolling depth, cast spoons for trout, and drag small plastics over granite for smallmouth; give low-light water a slower bottom pass.
How Union Valley Reservoir Fishes
The reservoir is part of the Upper American River hydroelectric system; compare shallow and deeper water. Water movement through that chain and cold snowmelt can change temperature quickly near inflows.
The main choice for the day is whether to follow kokanee schools and cold hydroelectric inflow while smallmouth use granite points. Make that decision before filling the deck with unrelated tackle; make the next cast parallel to the edge.
One shallow pass and one pass down the first break answer more than a long run; give low-light water a slower bottom pass. The comparison shows whether fish left the bank or simply stopped chasing fast lures; change retrieve speed before changing lures.
A small change in bottom can matter more than a dramatic shoreline; use a smaller lure in clear water. Feel for the first hard patch, channel lip, stump line, or clean weed edge and stay close to it; separate open-water fish from bank fish.
