The remaining water 1n Waneka Reservoir is used to irrigate about 190

acres of crops, including 48 acres of alfalfa, 48 acres of wheat or barley,

and 94 acres of corn. The present average water usage is approximately 2 1/2

Reservoir, Baseline Reservoir, and Marshall Reservoir as well as other direct

flow rights from the Lower Boulder Ditch, Coal Ridge Ditch, Leyner-Cottonwood
