Unified Interior Regions

U.S. Geological Survey Director Charles G. Groat will join a roster of leading earth scientists from industry and academia in looking to the future at the symposium "Natural Resources and Hazards: Challenges for the Twenty-First Century,"...

All-time record low river flows into the Chesapeake Bay were recorded for May, according to hydrologists at the U.S. Geological Survey (USGS). Flow into the bay has been below average for the last 10 months. Average daily freshwater inflow to the Chesapeake Bay in May was about 29.1 billion gallons per day (bgd), which is about 46 percent of the long-term average (62.6 bgd).

During March, river flow into the Chesapeake Bay and flow in the Potomac River averaged about 70% of the long-term average flow rate, according to the U. S. Geological Survey (USGS). 

At the end of February 1998, streamflow in the Potomac River at Washington, DC, and total freshwater inflow to the Chesapeake Bay were the highest on record, at about 39.9 billion gallons per day (bgd) and 152.4 bgd, respectively, according to the U. S. Geological Survey (USGS).

From evidence of exotic nutria damage to wetlands to above average sea level rise, the Chesapeake Bay watershed is a complex and compelling scientific challenge. 

Four months of dry weather are having a strong effect on freshwater inflow to the Chesapeake Bay, according to hydrologists at the U.S. Geological Survey (USGS). 

Evidence found by a team of U.S. Geological Survey scientists suggesting that the temperature of the Chesapeake Bay has increased over the past 400 years will be presented by paleontologist Dr. Stacey Verardo at the Annual Meeting of the Geological Society of America scheduled for Oct. 25-29 in Toronto, Canada.

A large meteorite plummeted into the western Atlantic Ocean about 35 million years ago, creating the 120-km wide Chesapeake Bay impact crater [Geology (Boulder), 22 (8), p. 691-694].

Streamflow in the Potomac River near Washington, D.C., was below average during September, but in the just-completed 1998 water year (WY98) year-long streamflow was the second highest on record, according to hydrologists at the U.S. Geological Survey.

Many of the fish lesions in Chesapeake Bay may be caused by a fungal infection rather than Pfiesteria, a U.S. Geological Survey scientist reported recently at the International Symposium on Aquatic Animal Health Conference in Baltimore

The steady precipitation over the Potomac drainage basin for the first several months of 1998 has resulted in a record-high flow of about 90 billion gallons per day (bgd) for the year so far, about 8% higher than flow by this time in 1996, when Potomac River flow set a new all-time high record of about 83. bgd.
