- A new oyster report released by the Chesapeake Bay Foundation in early July found that research suggests that oyster populations, especially in the southern Bay, may be developing resistance to diseases that have decimated oyster numbers in recent decades. For example, the annual average percentage of native oysters dying from the oyster disease MSX in Virginia’s York River decreased from 50 percent in 2000 to five percent currently, while occurrence of MSX in the lower James River decreased from about 80 percent in 1995 to about 24 percent in 2009. In Maryland’s Bay waters, oyster mortality from diseases decreased from 29 percent in the 1984-2004 period to 17 percent in the 2005-2009 period. Other key conclusions and assertions of the report are 1) that poaching, or illegal harvesting, is a common problem in Bay oyster sanctuaries; 2) oyster sanctuaries can provide significant economic return by enhancing reproduction of commercially valuable fish; 3) reconstructed reefs continue to be needed as oyster-attachment areas; 4) wa ter pollution is a significant obstacle to oyster recovery; and 5) oyster aquaculture offers greater potential for economic growth than does wild-oyster harvesting.

- Over the July 4th weekend, over 1,147 gallons of diesel fuel spilled from an Ammars, Inc., store in Bluefield, entered Beaver Creek, and eventually reached the Bluestone River, which flows across the state line into West Virginia. State agencies in Virginia and West Virginia were involved in efforts to contain the spill and in subsequent clean-up efforts, which are being conducted by consulting firm Marshall Miller. As of July 14, the extent of aquatic-life impacts were still being assessed. News Sources: Diesel spill tops 1,100 gallons - Bluefield (W. Va.) Daily Telegraph, 7/14/10, and Crews continue work to control diesel spill, Bluefield (W. Va.) Daily Telegraph, 7/7/10.
- As of the July 13 assessment by the National Drought Monitor, 86 percent of Virginia was rated as “abnormally dry,” and 37 percent of the state was rated as being in “moderate drought.” On July 14, the Virginia Department of Environmental Quality, or DEQ, issued a statewide drought watch. The DEQ’s news release announcing the watch said that, “Despite recent rain in portions of the Commonwealth, the potential exists for drought impacts to intensify if hot, dry conditions redevelop.” The state is recommending that localities, public water supplies, and self-supplied water users take the following steps: minimize non-essential water use; review or develop local water-conservation and drought-contingency plans, and take conservation or water-use restriction actions consistent with those plans; distribute water-conservation information to citizens; continue monitoring the condition of public waterworks and self-supplied water systems; and aggressively pursue leak-detection and leak-repair programs. News Sources: Virginia issues statewide drought watch, Virginia Department of Environmental Quality News Release, 7/14/10; and the U.S. Drought Monitor, http://drought.unl.edu/dm/monitor.html.

- And our last news item this week: In July, the Virginia Department of Transportation awarded a $424,000 grant to Mathews County for work to stabilize and protect its historic New Point Comfort island lighthouse. Since 1805, the lighthouse on the quarter-acre island has provided guidance to ships traveling Mobjack Bay, which separates the Middle Peninsula counties of Mathews and Gloucester. The new grant, coupled with a previous $149,000 grant and a 20-percent local match, will fund construction of a 12-foot high, 46-foot wide, and 300-foot long stone wall around the island. Construction is expected to begin in 2011. Meanwhile, a $10,000 donation by two descendants of Elzy Burroughs, the lighthouse’s original stonemason, has started a long-term fund for maintenance of the lighthouse.

This week we featured a new mystery sound: The rail clatter and warning horn of a train recorded from the Potomac River.
Many railroad lines developed along river courses, where cities and other commercial centers had originally located to take advantage of river-based transportation and commerce. Virginia examples include active railroad lines along parts of the Clinch, James, Roanoke, and Shenandoah rivers, as well as former lines now converted to recreational trails, such as the 57-mile long New River Trail State Park. For one example of the development of different transportation means along a river course, see “Scottsville Transportation” at the Web site of The Scottsville Museum, http://scottsvillemuseum.com/transportation/home.html. Information about the history of transportation along the Potomac River is available at the National Park Service’s Chesapeake and Ohio Canal Web site, at http://www.nps.gov/choh/index.htm. Information about New River Trail State Park is available at http://www.dcr.virginia.gov/state_parks/new.shtml.
