Major Findings for Sampleshed 1RP

* Steeper slopes - This sampleshed contains virtually all of the steeper land in the watershed ( 99% of overall watershed acreage with over 12% sloping land) (slope map).

* Large TSS and TP load - Represents 16% of the watershed acreage, but 74% of the TSS load and 46% of the TP load.

* Erosion - Streambank and gully erosion, and erosion from cultivated and non-cultivated highly erodible areas (map) are the primary sources of TSS and TP in this sampleshed.
