Where we work and where is the Lower Gunnison Watershed? Our watershed is located in western Colorado’s Gunnison and Delta counties. It includes the towns of Somerset, Paonia, Hotchkiss, Crawford, Cedaredge, Eckert, Orchard City, and City of Delta.
In the Lower Gunnison Basin average annual precipitation is only 19 inches, with most regions getting from 12-18 inches. The driest part of the basin is in Peach Valley east of Delta, with less than 8 inches of precipitation annually. The mountain areas are the wettest with the Grand Mesa and West Elk Mountains receiving more than 40 inches annually – mostly in the form of snow.
The watershed provides habitat for a variety of aquatic species, including native fish species such as the Colorado River cutthroat trout, flannelmouth sucker, bluehead sucker, roundtail chub, mottled sculpin, and speckled dace. Our watersheds provide world-class fishing and rafting, with 67 miles managed for Colorado River Cutthroat trout conservation. Species of concern that live within these watersheds include: the northern leopard frog, peregrine falcon, whooping crane, southwest willow flycatcher, bald eagle, greater sandhill crane, western yellow-billed cuckoo, and the river otter. A thorough report on wildlife is available at the Colorado National Heritage Program.
The Lower Gunnison Watershed includes the North Fork, Smith Fork, Surface Creek and Lower Gunnison River below the Aspinall Unit (Blue Mesa, Crystal and Morrow Point dams). River flows can be highly variable depending on snowmelt. Agriculture is the dominant water use in the basin, accounting for as much as 98% of water withdrawals. The Gunnison River is home to a world-renowned trout fishery.
