Manage irrigation development of the Clear Lake aquifer. Water level trends are reviewed annually to assess impacts to wetlands, lakes, and other water users. Water levels have been monitored since the early 1980’s and show declines caused by the 1980’s drought and recovery since the mid-1990’s. Current results show little or no impacts to wetlands and lakes. Water levels decline during the irrigation season but recover by the next spring. Results of a GWIP project produced a numeric model that will assist the SCCD evaluate any potential new permits in the South Medicine Lake area.
