I am a user of the Potomac and Shenandoah rivers and other smaller rivers in the area.  As a long time fly fisherman, canoe floater, and patron of the river I have witnessed the serious decline of the quality of these waters.  Runoff from new developments is a major contributor to this decline although there are other culprits as well.  I don't have many more years to enjoy these rivers but those who follow me will be denied the great pleasure given everyone by these wonders of nature if we don't act now to protect it.  I beseech you to listen to the citizens and not the developers and pass regulations to eliminate or greatly reduce the runoff problem.
