The report is required by Congress by Section 305(b) of the Clean Water Act. This water quality assessment summarizes Vermont’s water quality conditions for 1998 and 1999 and includes updated water resources program information for rivers and streams, lakes and ponds, wetlands and groundwater. The report contains detailed water quality information from round 2 of the rotational assessment, including the Poultney/Mettawee River watersheds, the Ottauquechee/Black River watersheds and the Stevens/Wells/Waits/ Ompompanoosuc River watersheds. The report also includes updated cost/benefit information, monitoring, beach closures, among other information. The water quality assessment found that 78% of Vermont’s total assessed river and stream miles (5,261 miles assessed) fully support all water uses. Of 53,350 lake acres assessed, 22,940 acres (43% of lake acres assessed) fully support all uses. If the EPA guidelines regarding the fish consumption advisory were applied in their strictest sense, none of the state’s surface waters would fully support water uses. However, states have been advised to assess their waters without the advisory so other polluting sources would not be “masked” by the mercury advisory. Common pollutants found in the assessed waterbodies include silt, pathogens and nutrients, which come from eroding stream/lake banks, urban areas and agricultural lands. Additional causes of pollution occurring in certain of the state’s watersheds include thermal modifications, organic enrichment/low dissolved oxygen, flow alterations, habitat alterations metals, noxious aquatic plants, and exotic species. Sources of these pollutants include atmospheric deposition, natural sources, flow regulation and habitat alterations, among others. Many of Vermont’s lakes and rivers have been cleaned up by construction of approximately 150 municipal and industrial waste water treatment facilities. However, as you can see from the figures above, much work needs to be done to complete the clean-up job - primarily to reduce pollution from nonpoint, or dispersed sources. We are indeed fortunate to have many volunteer groups around the state to assist us in this important work. As of last count, there were active watershed or lay monitoring groups on approximately 26 rivers, 31 lakes and 36 Lake Champlain stations. Their work is truly needed and greatly appreciated. Your comments on the report or other comments or suggestions on ways to improve Vermont's water resources are always welcome. Please write to me or call me at the above phone number.
