The Drywood Creek Sub-watershed contains a lot of open space, several lakes, and many wetlands existing mainly in the western portion of the watershed. The main land use here is agricultural and pasture usage. Though no lake assessments have been made beyond the statewide Mercury TDML, the Drywood lakes would most likely be labeled as impaired in the future sampling data that suggest high nutrient levels. Due to a number of stressors that effect the water quality within this area, the Drywood Creek watershed could be contributing greatly to the impairments downstream on the main stem of the Pomme de Terre River.
Drywood Creek is listed as impaired for several parameters including E.Coli, Turbidity, low dissolved oxygen, and both fish and macroinvertebrate biology which are likely attributed to the watershed’s stressors such as Nitrates, altered hydrology, and low habitat scores.
