Fish species in Union Lake

Union Lake is a lake in Trinity County, California and covers about 0.1 acres, reaches about 4.2 feet at its deepest point and holds roughly 0.1 acre-feet.

Union Lake is small water, so a careful lap around the bank can show most of the useful cover. With little deep water in Union Lake, weeds, wind, and water color can matter more than depth alone.

Fish and Baits

Fish listed for Union Lake include Brook Trout, and Rainbow Trout.

While looking for rainbow trout on Union Lake, cast a small spoon, inline spinner, light jig, or fly through cool water.

How to Read the Water

Make one shallow pass and one deeper pass on the same shoreline; that shows whether fish are tight to cover or using the first break; start beside the first useful break, then look for a second bite before leaving.

Season by Season

Early in the year, protected water and the first warm afternoon can be the best clues; as the water heats up, check deeper edges without assuming every fish is on the bottom; cooling fall water often makes points and firm banks useful again; search one cove before changing areas, then pause longer when cold water slows the bite.

A Simple Tackle Plan

A light spinning rod, thin line, a few small spoons, inline spinners, and jigs cover the listed trout; carry one slightly heavier setup when other fish or windy water call for more control; check both sides of the point; follow the outside weed line, then repeat the first clean pattern.

Record the wind, water color, depth beside the useful cover, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce; try deeper shade during summer afternoons, then use a smaller lure in clear water.
