Project Objectives:Project Objectives: 

1. Measure concentrations and estimate annual loading of plant nutrients, total suspended solids (sediments) and metals

2. Examine physical habitat conditions of the streams and conduct bioassessments utilizing benthic macroinvertebrate communities

3. Using GIS technology, examine and quantify land cover for the entire Sougahatchee Basin from 1993 and 2001 satellite

imagery and aerial photography

4. Using regression analysis, examine relationships between basin land cover, nutrient and sediment loading and biological condition of the streams

*EPA recommends 0.05 mg/L as the maximum concentration of total phosphorus for flowing streams entering a lake.

**0.1 mg/L = 1 ounce in 80,000 gallons of water
