The objective of the program is to monitor mid-summer water chemistry and algae concentrations in Little Bitterroot Lake and its tributary and outlet streams. Lake stratification is also evaluated by collecting water chemistry and algae data at depth near the lake center. The data is used to collect baseline data, evaluate existing trophic status of the lake, monitor trends from 1999 to present, evaluate effects of activities within the watershed (subdivisions, road building, logging and slash burning, harvesting of aquatic vegetation), and address any emerging trends or issues with water quality in the lake and surrounding watershed.
