Land Use Planning Impacts on Near Shore Pollution Loading in the Great Lakes

Great Lake Summary: Huron

There are 17 subbasins in the Lake Huron drainage basin. To view reports for the individual subbasins, select an area below:


Shoreline

Lake Huron's shoreline was analyzed using i-Tree Hydro to determine the impact of current vegetative and impervious surfaces on annual runoff quality and quantity. For more information on how each subbasin was simulated with i-Tree Hydro, refer to any subbasin page.

Nutrient Loading

The i-Tree Buffer model is built upon the framework of Endreny and Wood (2003) and creates maps of watershed runoff likelihood and buffering likelihood values. This analysis used publicly available GIS inputs, annual rainfall data, and local (White et al., 2015) values for nonpoint source (NPS) loading of nutrients

For more information on how each subbasin was simulated with i-Tree Buffer, refer to any subbasin page.
