The quality of the water we drink can potentially impact our health. The USGS has several programs and cooperative projects that characterize the quality of selected rivers and aquifers used as sources of drinking water to community water systems in the United States.

USGS streamgage 13210810, Fifteen Mile Creek near Middleton, Idaho, is one of 10 streamgages the USGS has installed on Treasure Valley drains in cooperation with the Idaho Department of Water Resources. Data from these streamgages will be incorporated into a groundwater-flow model of the Treasure Valley aquifer system.
