The Fish of Curecanti
The fishery of the Gunnison area has been changed by the three dams of the Wayne N. Aspinall Unit which form the reservoirs of Curecanti. Where once the fish of the Gunnison River fed upon the aquatic insects of the area, new fish species, which make their home in the reservoirs, feed upon plankton, small microscopic plants and animals.
Federal and state fish hatcheries stock over three million fish in the reservoirs each year.
RAINBOW TROUT Oncorhynchus mykiss
The colorful rainbow trout, named for the pink stripe along its side, is the most often caught fish of Curecanti. Rainbow trout, introduced into the Gunnison River in the 1880’s, are stocked quite heavily and can be caught in the river areas or in the reservoirs. River and shore fishing can be very productive, but in the late summer when waters are warm, the fish seek cooler areas. Then, trolling at slow speeds works best.
LAKE TROUT (Mackinaw) Salvelinus namaycush
The deep subsurface canyons of Blue Mesa Reservoir provide excellent habitat for the big lake trout or mackinaw. The “mac” can reach tremendous sizes - one monster weighed forty-six pounds! To catch one of these “big ones”, you must fish deep and in cold water
BROWN TROUT (German) Salmo trutta
The spotting pattern is composed of black spots and also red-orange spots surrounded by light blue.
BROOK TROUT Salvelinus fontinalis
Brook trout live in most of the streams which feed the reservoirs of the recreation area. Curecanti Creek, which feeds into Morrow Point Reservoir, can be one of the best spots for catching the “brookies”.
KOKANEE SALMON Oncorhynchus nerka
The salmon are stocked from the Roaring Judy Fish Hatchery north of Gunnison. When they are ready to spawn at the end of their third or fourth summer, they travel upriver to return to the hatchery. At this time, they no longer feed, and after they reproduce, they die.
In order to insure that a sufficient number of eggs are collected and fertilized, the snagging of kokanee salmon is only allowed during November and December. Between August 1 and October 31, all salmon caught east of the Lake City Bridge must be released.
YELLOW PERCH Perca flavescens
Slightly greenish with yellow sides and darker vertical stripes.
A light colored bottom feeding fish.
CUTTHROAT TROUT Oncorhynchus clarki
The only native trout found here, cutthroat's can be found in streams leading into the reservoirs. Similar in appearance to rainbow trout, the identifying feature of a cutthroat is a red “slash” mark under lower jaw.
Genetically a combination between a rainbow and cutthroat trout, cuttbows look like a mix between the two. While cuttbows typically aren't found in fish field guides because they are in interbreed, they can be found in Morrow Point and Crystal Reservoirs.

Did You Know?
The average precipitation at Curecanti is only 12" a year, which is why there are few trees around Blue Mesa Reservoir.
