Wet weather use on forest roads can be a significant source of turbidity and fine sediment in streams that in turn may be detrimental to aquatic organisms including salmonids. Regulations governing traffic use during wet weather in the Pacific Northwest have become increasingly restrictive with water quality in mind. Current methods of design for forest roads do not consider the environmental performance of roads and little research has been conducted on design methods to minimize sediment production from forest roads.
