ET Weather Stations

SMWD has two weather stations connected to the California Irrigation Management Information System (CIMIS) which provides 24/7 monitoring of local weather. The District's budget-based tiered rate structure uses daily evapotranspiration (ETo) data based on accounts' billing cycles to calculate outdoor water budgets.
