This is the final Erosion potential model.  Areas in red and orange and dark yellow impact the water quality through erosion more than the grey areas.  The northeast corner of the lake has very high impact and this is most likely due to the developed land use, steeper slopes, and its proximity to the lake.  Wetlands are the very light grey areas.  These actually absorb erosion before it reaches the lake.
   This model would be very useful for focusing remediation and erosion control efforts.  This may take the form of strengthening buffers around streams and cleared land as well as keeping roads well maintained.
