Presentation #1: Understanding Phosphorus Loading in Riparian Areas
Land use in the riparian area can have a disproportionate impact on surface water quality because there is only a small amount of land between where precipitation falls and the lake. Water quality monitoring and sediment core analysis can help us understand and quantify increased phosphorus loading from shoreland development. This data can help resource managers confidently use runoff coefficients from various land use to estimate phosphorus loads to various types of lakes.

Presentation #2: Modeling Phosphorus Reduction from Small Projects on Riparian Properties
Lake organizations are often looking for ways to compare the relative cost and benefits of different shoreland improvement projects. Quantifying the nutrient reductions that might be achieved from installing raingardens or restoring shoreland buffers is one way to help explain why these are important projects for the group to take on. This presentation will walk through some examples of how you can develop reasonable estimates of phosphorus reductions in the riparian areas.
