Stream Monitoring of Selected Sub-watersheds of Conesus Lake

North McMillan Long Point Control Watersheds Sutton Point

Graywood Sand Point Experimental Watersheds Cottonwood Southwest

Stream Monitoring Overview Discharge Water Chemistry Combine Discharge and Chemistry to get Mass Losses from each Watershed to Conesus Lake

Stream Monitoring Overview Discharge –Continually monitor stream level combined with velocity and cross-sectional area to calculate continuous discharge Water Chemistry –Phosphorus, Nitrogen, Suspended Solids, and Sodium –Non-event conditions - weekly –Event conditions - as they occur

Overview to date: 16 months of continuous discharge, weekly baseline sampling on 7 streams 21 events sampled automatically 714 Water samples delivered to the laboratory 4246 Water quality analyses completed Data continuously disseminated via web site

Year 1 Results August 2002 to August 2003

Initial attempts at BMP Evaluations September to December for each year

Conclusions Rating curves in place for the 7 streams Year 1 discharge and loading summarized Stream monitoring to continue The year 1 data is low – may be troublesome Begin to build tools to evaluate the impact of the implementation of BMP’s More data / time is needed to evaluate the success of the BMP’s
