The time has come to seriously address the reality of excessive sediment seeping into our waterways. As the population continues to grow strongly, and in some areas explosively, the old rules and regulations are just not strong enough to prevent an inevitable increase in harmful sediment. Many harmful chemicals (such as potassium) enter our waterways attached to tiny particles of sediment. I own a river outfitting business on the Shenandoah River in Warren County, Virginia. I have observed the river on a daily basis for seven months every year for the past 35 years. It is my observation the algae blooms on the river are increasingly more pronounced and sustained over the past decade. Also, consistant mud deposition at all our landings after high water is much more of a problem now than in the past, creating a stinking mess that I now have to devote manpower and resources to at least make tolerable. The choices are stark. Either we strengthen our control of sedimentation, or we go backwards. The status quo will not do. We at Downriver Canoe Company therefore support the recommendations made by the Shenandoah Riverkeeper and Potomac Riverkeeper to strengthen and update the Construction General Permit regulations.
