- Efforts to reduce nutrients and sediments reaching the tidal Potomac River led to significant water quality improvements in the river between 1990 and 2007, according to a study published by researchers from the U.S. Geological Survey (or USGS) and England’s National Oceanography Centre. The September 7 USGS news release on the study states tha t “[s]ince 1990, the area covered by [submerged aquatic vegetation, or SAV] in the lower Potomac has doubled [to 8441 acres], the area covered by native SAV has increased ten-fold [to 3081 acres], the diversity of plant species has increased, and the proportion of exotic species [especially Hydrilla] to native species has declined as nutrients have declined.” The study covered a 50-mile stretch of the tidal Potomac below Washington, D.C. News source: Potomac River: Ten-fold Increase in Native Submerged Vegetation Reflects Improved Water Quality, U.S. Geological Survey News Release, 9/7/10. More information: The report, “Long-term reductions in anthropogenic nutrients link to improvements in Chesapeake Bay habitat,” was published in the September 7 issue of the Proceedings of the National Academy of Sciences and is available online at http://www.pnas.org/cgi/doi/10.1073/pnas.1003590107.
- On September 8, Old Dominion Electric Cooperative, or ODEC, announced that it is postponing for 18-24 months any action toward acquiring air permits for its proposed coal-fired power plant in Surry County. In a news release, ODEC attributed the postponement to a decrease in demand for electricity as a result of the recent economic recession. Prior to the postponement, ODEC was in the process of seeking several dozen state and federal permits needed for the Surry site. The cooperative also has the option of using a site in Sussex County. ODEC has already received local land-use permits, although some local residents have filed a lawsuit challenging those permits. ODEC’s news release said that the cooperative will continue to work with local property owners to secure the rights-of-way for a water pipeline from the James River to serve the proposed plant. The $4-6 billion plant would have a capacity of 1500 megawatts, making it Virginia’s largest coal-fired power plant.

- And our last news item this week focuses on Virginia’s lingering drought. As of the September 14 National Drought Monitor, more than two-thirds of Virginia was “abnormally dry,” while most of the eastern third of the state was in “severe drought” and parts of Frederick and Shenandoah counties were in “extreme drought.” At least 65 percent of Virginia has been abnormally dry since late June, and the severe drought area has persisted since early August. Low stream flows are one result: As of September 16, seven-day average stream flows were below normal at 66 percent of U.S. Geological Survey gaging stations in Virginia. The low rainfall and low-water conditions are causing agricultural impacts and water-use restrictions. The September 17 Richmond Times-Dispatch reported that 46 localities have requested agricultural disaster assistance, while nine localities have imposed mandatory water-use restrictions and 17 localities have implemented voluntary restrictions. Unfortunately, things may get worse: As of September 16, the seasonal drought outlook from the National Weather Service’s Climate Prediction Center forecast that drought conditions would persist or intensify in most of eastern Virginia through December, with slight improvement forecast for some areas. News sources: State's drought could quickly become much worse, Richmond Times-Dispatch, 9/17/10; U.S. Geological Survey’s WaterWatch Web site, 9/17/10; National Weather Service’s Climate Prediction Center, Seasonal Drought Outlook for September 16, 2010. More information: The National Drought Monitor’s weekly assessment has five categories of increasingly worse drought: D0 = abnormally dry; D1 = moderate drought; D2 = severe drought; D3 = extreme drought; and D4 = exceptional drought.
WATER SOUNDS AND MUSIC
This week we feature a mystery sound: The Belted Kingfisher
[7-25-14 note: Please see Episode 224, week of 7-28-14, for an episode on the Belted Kingfisher.]
Besides being found in the Virginia Water Radio logo, Belted Kingfishers are found commonly throughout North America around streams, rivers, ponds, lakes, and estuaries. This bird is known for its habit of hovering above water and then diving to capture fish. Kingfishers burrow into banks beside a water body to make their nest, and their rattling call is used to defend their territory. This week's recording recording was provided by Lang Elliott of NatureSound Studio. Information on Belted Kingfishers was taken from A Guide to Field Identification of Birds of North America, by Chandler S. Robbins et al., St. Martin’s Press, 2001 edition; and the Cornell Lab of Ornithology’s Bird Guide Web page at http://www.allaboutbirds.org/guide/search.
