Gross Reservoir Popular Fish - Brown Trout

Brown Trout

Currently, fishing for brown trout in Gross Reservoir, CO is delivering some nice catches. These hearty fighters migrate around the lake in search of baitfish and comfortable water temperatures, preferably in the 50 to 62 degree range. In spring brown trout, along with the baitfish, move to the shallows which warms first. As the days get warmer in summer they move deeper, again following schools of bait. As Fall and Winter arrive, browns tend to stay in deeper water. When these trout move deep, it is typically in the 20- to 45-foot range. Nightcrawlers are always a good bait for brown trout. In-line spinners, bait-colored crankbaits and small spoons are other options. Experiment with depth and retrieve speed. When the lake freezes over, try your luck at ice fishing.

In winter, once the ice is safe, try ice fishing for kokanee.
