This report documents the distribution of submersed aquatic vegettation collected in the tidal Potomac River and transition zone of the Potomac Estuary during 1987. Maps illustrate the distribution of submersed aquatic plants and Hydrilla verticillata int he tidal Potomac River, based on shoreline surveys. Species of submersed aquatic plants found on vegetated transects in the transition zone of the Potomac Estuary are reported for each transect location. Regrowth of harvested Hydrilla is presented for four mechanically harvested sites. Data on the distance from shore and greatest depth of water in which aquatic plants grew on four transects and on Secchi depths throughout the study reach are reported. These data can be used to quantify changes in water clarity and plant distribution.
