The Pamunkey watershed (HUC 02080106) covers an area of approximately 1,009 square miles in Virginia. It is largely forested and includes portions of five counties. The watershed is primarily composed of two major rivers, the Pamunkey and the North Anna, and their tributaries. These rivers play a crucial role in supplying surface water to the region and supporting aquatic habitats. The watershed experiences a temperate climate with mild winters and hot summers. Snowpack is generally minimal but can occur during particularly cold winters. The surface water in the watershed is primarily used for drinking water, irrigation, and recreation. The water quality of the Pamunkey watershed has been compromised in recent years due to pollution from agricultural runoff, urban development, and industry. In particular, the watershed has seen an increase in sediment and nutrient pollution, leading to harmful algal blooms and degraded aquatic ecosystems. Overall, the Pamunkey watershed is an important resource for the region, but efforts are needed to protect and restore its water quality and habitat.
