This report summarizes the water quality monitoring data and observations gathered during the 2015 El
Dorado Trout Unlimited (EDTU) Cosumnes River Monitoring Program season. It also includes data
from the California Water Resources "Safe to Swim" report and river community observations. UC
Davis Cosumnes Preserve monitoring data will be included when it becomes available later this year.
EDTU has embarked on this long term monitoring program to provide data to support a watershed
scale assessment and restoration effort, which includes the entire watershed basin that drains water to
the Cosumnes River. EDTU is working with a Coalition of partners from a variety of regional
organizations, including non-profit/non-governmental organizations; local, state & federal agencies;
Tribal entities; communities; water districts; and private citizens who have an interest in collaborative,
effective stewardship of the Cosumnes River.
