aggravate these erosive conditions through soil disturbance. Increased 

 water yields or alteration of runoff flow timing (from forestry practices) 

 may initiate channel instability and high sediment loads. 



Prevention and mitigation measures must be applied on a basin -wide basis 

 to effectively deal with non-point pollution in the Clearwater River 

 drainage. The most comprehensive measures include: 1) restriction of 

 silvicultural (and other) activities that could further impact existing 

 problem areas; 2) conduct basin-wide inventories to assess physical 

 limitations and natural hazards of the watershed and identify water 

 resource needs; 3) coordination of silvicultural (and other) activities 

 among various land managers in accordance with watershed limitations, 

 particularly in drainages already impacted; 4) pursue watershed rehabili- 

 tation and protection measures (i.e., reforestation, road reclamation, 

 streambank stabilization); 5) promote or require use of BMP's in 

 silvicultural activities.
