• ORGANIZE A VISUAL ASSESSMENT OF YOUR WATERSHED! Learn about the work of the Ridley Creek EAC and then motivate your EAC to organize a visual stream assessment in your watershed. The EAC of Ridley Creek recruited over 70 volunteers to conduct a visual assessment of the overall health and functioning of their stream. The results included valuable information on vegetative buffer width, stream bank stability, fish habitat and surrounding land use. Using this online assessment tool, your EAC can also garner information on the water quality in your watershed. Visit this site to see results and their meanings in interactive maps presented with cutting edge Scalable Vector Technology (SVT). Return to Other Presentations.
