The Recovery Program works cooperatively with water and power customers and landowners to improve fish habitat. Projects include constructing fish passages at diversion dams for endangered and other native fishes; screening diversion canals to keep fish from entering and becoming trapped, and acquiring and restoring floodplain habitat to serve primarily as fish nursery areas.
Some recovery measures benefit more than just the endangered fish. In some locations, river habitat improvements increase the regeneration of cottonwoods and willow trees along the river. Cottonwoods and willows are in important source of food and shelter for birds and mammals and provide a shady and pleasant place to enjoy the river.
