What common everyday item owes it origin—in part at least—to the following men, all active from the mid-1800s to the early 1900s: James Maxwell, Heinrich Hertz, Nikola Tesla, Alexander Popov, and Guglielmo Marconi? All of these men, along with other scientists and engineers, contributed to the invention or development of the radio. From Robert Peary’s 1909 message upon reaching the North Pole, to the World War II messages from Franklin Roosevelt and Winston Churchill, to the daily talk shows that enliven and influence politics and culture in 2010, radio has been an indispensible part of modern communications. The Virginia Water Resources Research Center is trying to use this old, reliable technology—matched with some 21st Century enhancements—to give Virginia citizens another way to stay informed about our state’s water resources. -

1 NOMINATION. Richmond Highway Corridor ATTACHMENT A. Revise and strengthen land use and transportation recommendations of the Plan for Richmond Highway Corridor to reduce stormwater runoff, be consistent with county watershed plans, and support the Policy Plan’s environmental objective 2, policy k. 1. Revise and update the description of the Richmond Highway Corridor Area to reflect current knowledge about environmental impacts, esp. on water quality. To the following existing paragraph (p. 25), The northern part of Richmond Highway is located in the Belle Haven and Little Hunting Creek watersheds, while the southern segment is in the Dogue Creek watershed and is affected by the floodplains and stream valleys of Dogue Creek. The entire corridor is located in the Coastal Plain geologic province and thus lies in a zone of extensive slippage-prone swelling clays and sensitive aquifer recharge. add Development in the Richmond Corridor has degraded all three of these watersheds by increasing stormwater runoff from impervious surfaces and decreasing aquifer recharge. 2. Add a land use recommendation to p. 27: Offer incentives for development and redevelopment projects to reduce imperviousness and achieve better control over stormwater runoff in the Richmond Highway Corridor. Possible incentives to be created were recommended by the Little Hunting Creek Watershed Plan and are described in Attachment B. It is recommended that an overlay district, as suggested by the watershed plan, be created to implement these changes in the Richmond Highway Corridor as soon as possible, without waiting for county-wide changes in policy. The urgency is due to the inadequacy of stormwater controls in the Richmond Highway Corridor and consequent damage to three watersheds, the Potomac River, and the Chesapeake Bay. -

Middle Potomac River Watershed Assessment: Potomac River Sustainable Flow and Water Resources Analysis. Final Report. 107 pp. and 11 appendices. Cover photograph: Great Falls on the Potomac River as seen from Virginia. Jim Palmer (ICPRB) Middle Potomac River Watershed Assessment Abstract The Middle Potomac River Watershed Assessment (MPRWA) was a collaborative effort to assess the relationship between streamflow alteration and ecological response in the Potomac River and its tributaries in a study area defined as the Middle Potomac. The assessment is comprised of five distinct components: (1) a large river environmental flow needs assessment, (2) a stream and small rivers environmental flow needs assessment, (3) a projection of future water uses, (4) a stakeholder engagement process, and (5) development of a concept or scope for a strategic comprehensive plan for watershed management. This information can be used to balance and mitigate water use conflicts and prevent ecological degradation. To assess flow needs in the Potomac watershed, the Ecologically Sustainable Water Management (ESWM) approach was used for large rivers and the Ecological Limits of Hydrologic Alteration (ELOHA) framework was adapted for streams and small rivers. In the large rivers included in this study, based on currently available information, there has been no discernible adverse ecological impact on focal species due to human modification of flows. -

A Second Bird Survey at Washington, D. C
34 THE WILSON BULLETIN-NO. 103 The nests were made of sycamore down without lining. One of the eggs is somewhat larger than the other, which is often the case with sets of humming birds’ eggs, and is usually explained on the theory that the smaller egg will hatch into a male bird and the larger one into a female. Sometime ag.o I had the good fortune to find a nest of the Ruby-throated Hummingbird on an apple tree branch near my home at Willoughby. The nest contained two fresh eggs. While looking around I noticed a second nest a few feet away, and upon examining it found that it was a last year’s one. Both nests had probably been made by the same pair of birds, for aside from the discoloration and weathering of the old nest, the two were identical in size, shape and gen- eral appearance. This, coupled with the fact that they were located within a few feet of each other, makes it almost cer- tain that they were built by the same pair of birds. These are interesting examples of the wonderful instinct which guides even the tiniest of birds over thousands of miles of territory to their favorite summer nesting haunts. In the case of the Black-chinned Hummingbird, however, it is quite possible that the builders of the double nest, owing to the mild climate of Southern California, had never strayed very far away from the place it was found.
