Nutrient Load Summaries for Major Lakes and Estuaries of the Eastern United States, 2002

Categories: Chesapeake Bay,Environment,Maps/Geography,Natural Resources,Virginia Issues

Provides estimates of sources and stream transport of harmful nutrients to 255 major lakes and 64 estuaries in the eastern U.S. including major rivers of Virginia and the Chesapeake Bay tributaries.   From the U.S. Geological Survey


Land and Water Quality Protection in Hampton Roads: Phase II

Categories: Chesapeake Bay,Environment,Natural Resources,Virginia Issues

Provides guidance to local governments on best stormwater management practices for coastal areas, includes a review of two Hampton Roads localities to identify policy changes, and demonstrates the use of geographic information systems to improve the site design process.  From the Hampton Roads Planning District Commission


Land Subsidence and Relative Sea-Level Rise in the Southern Chesapeake Bay Region

Categories: Chesapeake Bay,Environment,Geology/Mining,Headlines,Virginia Issues

Discusses why the southern Chesapeake Bay region has the highest rate of sea-level rise on the Atlantic Coast.  Finds that extensive groundwater pumping in the region and the flexing of the earth’s crust in response to glacier formation and melting are major causes of land subsidence in the region.  From the U.S. Geological Survey


Quantifying Groundwater’s Role in Delaying Improvements to Chesapeake Bay Water Quality

Categories: Chesapeake Bay,Environment,Natural Resources,Virginia Issues

Describes a project to determine the time required for the effects of nitrogen-reducing best management practices to result in improvements in water quality of the Chesapeake Bay.  From the U.S. Geological Survey and Environmental Science & Technology Journal


Deriving Chesapeake Bay Water Quality Standards

Categories: Chesapeake Bay,Environment,Natural Resources

Reviews the derivation of the water quality criteria, criteria assessment protocols, designated use boundaries, and their refinements as listed in 6 addendum documents since 2003 and adopted into each jurisdiction’s water quality standards for developing the Chesapeake Bay Total Maximum Daily Load.  From the U.S. Geological Survey


NOAA, Partners Predict Possible Record-Setting Dead Zone for Gulf of Mexico

Categories: Chesapeake Bay,Environment,Natural Resources,Virginia Issues

Press release on size of dead zones (areas of low or no oxygen) in Gulf of Mexico and Chesapeake Bay in 2013.  From the National Oceanic and Atmospheric Administration


Total Nutrient and Sediment Loads, Trends, Yields, and Nontidal Water-Quality Indicators for Selected Nontidal Stations, Chesapeake Bay Watershed, 1985-2011

Categories: Chesapeake Bay,Environment,Natural Resources,Statistics,Virginia Issues

This report documents flow-adjusted trends in sediment and total nitrogen and phosphorus concentrations for 31 stations in 1985-2011 and for 32 in 2002-2011.  For 2006-2011 period, 65 stations are covered.  From the U.S. Geological Survey


A Regional Classification of the Effectiveness of Depressional Wetlands at Mitigating Nitrogen Transport to Surface Waters in the Northern Atlantic Coastal Plain

Categories: Chesapeake Bay,Environment,Natural Resources,Virginia Issues

Discusses the damage from excessive nitrogen in Chesapeake Bay and Pamlico Sound  and Atlantic coastal plain streams.  From the U.S. Geological Survey
