Dillon Reservoir is a prime location for summer or winter fishing. The lake is home to Brown Trout, Rainbow Trout, Kokanee Salmon, and Arctic Char. With 26 miles of shoreline, finding a nice secluded spot to cast is not a problem.
A brief history of fishing conditions on Dillon Reservoir The Mysis shrimp was introduced into Dillon Reservoir in 1970 as a food source to fatten trout and salmon. But the small nocturnal crustaceans missed the trout’s daytime feeding patterns and began eating all of the zooplankton — leaving salmon and trout hungry and small.
The Arctic char was introduced to the reservoir in 1990 to see if they would feed on the shrimp — the main part of their diet. Colorado Parks and Wildlife manages the fishery; Arctic char was stocked in Dillon in 1990, 1992, 1996, 1998, and 2008 to 2011. The reservoir is the only public fishery in the lower 48 states outside of Maine where anglers have a chance of landing the prized fish.
The fishing ecosystem at Dillon Reservoir has been steadily improving since the early 90’s thanks in part to the introduction of Arctic Char by the Colorado Division of Wildlife. Typically found only in Arctic waters, this cold-water fish — a species of trout — has helped turn the reservoir into an angler’s paradise.
