Reservoir Levels Weather Hydrology

Foster Lake is a reservoir located near the city of Foster in Oregon. The lake was created in 1968 as a result of the construction of a dam on the South Santiam River. The reservoir is regularly used for irrigation, and also supports recreational activities such as fishing, boating, and camping. The hydrology of Foster Lake is influenced by its location in the Cascade Mountains and its proximity to snowpack providers. The South Santiam River is the primary surface flow into the lake, and snowmelt from the nearby mountains contributes to the lake's water level in the spring and early summer. The lake and surrounding area also support agricultural activities, with farms and ranches located nearby. Overall, Foster Lake is an important resource for the local community, providing water for irrigation and supporting a variety of recreational and agricultural uses.
