This report summarizes data on the distribution and abundance of submersed aquatic vegetation collected in the tidal Potomac River and Estuary during 1986. Plant species were identified and dry weight determined for selected sites sampled in spring and fall. The percentage of each plant species was determined in areas of high plant density in the fall. Water quality characteristics measured include temperature, specific conductance, dissolved oxygen, pH, and transparency as indicated by Secchi depth. Maps were made of the distribution of submersed aquatic vegetation based on transect samples and a complete shoreline survey.
