| Abstract |
On the basis of water quality problems associated with nutrients, Big Millpond, in the Chincoteague Bay watershed (02-13-01-06), was identified on Marylands 1998 list of WQLSs as being impaired. Subsequent analysis associated with the nutrient TMDL evaluation revealed an excessive sedimentation problem. This document proposes to establish Total Maximum Daily Loads (TMDLs) for the nutrient phosphorus and sediments entering Big Millpond. Big Millpond is an impoundment located near Welbourne in Worcester County, Maryland. The impoundment lies on Swans Gut Creek, draining to Chincoteague Bay. Swans Gut Creek lies in the Chincoteague Bay Drainage Basin, in the Lower Eastern Shore of Maryland. Big Millpond is an artificial impoundment owned by Worcester County. Its main purpose is for recreation. Big Millpond is impacted by a high sediment load, resulting in excessive sedimentation of the reservoir and loss of reservoir volume. This threatens the ability of the water body to maintain and support fishing, and propagation of fish and other aquatic life. The reservoir also experiences occasional nuisance algal blooms, due to over enrichment by nutrients, which interfere with recreational uses. The death and decay of excessive algae can cause violations of the water quality standard for dissolved oxygen (DO), causing a disruption of the lakes ecosystem balance and cause fish kills. Analysis suggests that phosphorus is the limiting nutrient for the production of algae in freshwater lake systems such as Big Millpond. Due to the propensity of phosphorus to bind to sediments, the overall strategy is to simultaneously address the water quality problems associated with phosphorus and sediments. |
