The lake is bordered by the Colville National Forest on one 

 side and Kaniksu National Forest on the other side in the northern 

 part. South of the National Forest area is the Colville Indian 

 Reservation on the west side and the Spokane Indian Reservation on 

 the east. Principal industries of the region are stock grazing, 

 wheat farming, diversified farming on a small scale, lumbering and 

 mining. 



The climate of Roosevelt Lake is influenced by the prevailing 

 westerly winds, which produce five to ten inches of precipitation in 

 the lower twenty miles of its watershed. This moisture supports a 

 growth of bvinch gr?».ss of the type charscteristic of plains grasslandp 



The remaining portion of the reservoir, with ten to thirty inches 

 of rainfall, is forested with yellow pine, Douglas fir. Western larch, 

 and Western white pine. Normal air temperatures are 32 E, in 

 January and 68° F., in July (Ooode, 1948),
