Description: This dataset consists of a digital geospatial representation of all identified Tier II segments in the State of Maryland. Based on data collected between 1995-2015, this dataset currently contains information for 253 designated Tier II stream segments. Main segment breakpoints were determined using the 100,000:1 National Hydrography Dataset (NHD). The final designated Tier II segments are the merged sub segments that make up the 24,000:1 NHD meeting the 100,000:1 breakpoints. Tier II stream segments generally terminate at confluences, impoundment outfalls, and tidal boundaries. Last Update: 9/11/2016 Contact: Angel D.
