North Carolina Small Ponds Under 10 Acres, 2022
Ponds are impoundments that have been used for flood control, water supply, irrigation, and recreation. They constitute modifications to the stream network that fragment the aquatic habitat by limiting river network connectivity necessary for fish passage. A dataset was developed to quantify small ponds as proxy measures of barriers to flow in stream networks across the State of North Carolina. The USGS used a combination of the 2016 National Land Cover Dataset (NLCD) and the National Hydrography Dataset (NHD) Plus High Resolution to identify 105,560 small ponds that are less than 10 acres in size. The features are more refined than larger scale assessments such as those in the NHDPlus High Resolution and provide a starting point for determining mitigation strategies.
