EXAMINING NUTRIENT DYNAMICS IN WATERFOWL IMPOUNDMENTS IN COASTAL NORTH CAROLINA
Anthropogenic nutrient loads result in eutrophication of aquatic ecosystems, causing harmful algal blooms in surrounding water bodies. Lake Mattamuskeet (Hyde County, NC) is a large coastal lake that has recently experienced declines in submerged aquatic vegetation (SAV), an indicator of high nutrient conditions. Due to flat topography throughout the watershed, hydrology is altered using pumps to drain for agriculture or flood for waterfowl habitat. This project represents a larger effort to better understand the factors contributing to decline in water quality and SAV in the lake. To this end, high temporal resolution data (30 min) collected using UV-Visual spectrometers and multi-parameter sondes at a waterfowl impoundment and an agricultural field that is seasonally modified as a waterfowl impoundment part of the year. Specifically, water levels and water chemistry (e.g., nitrate, total suspended solids, total dissolved nitrogen, dissolved organic carbon) are monitored. Quantifying nutrient dynamics as hydrology is actively managed may ultimately contribute to developing best management practices that reduce nutrient exports and restore SAV of this aquatic ecosystem.
