Unified Interior Regions

No, not another meteor disaster movie, but something left a big impression in the Chesapeake Bay.

Has the Potomac River been looking a little dry lately? Hydrologists -- i.e. water specialists--with the U.S. Geological Survey (USGS) will measure the potentially serious effects of the intense heat and lack of rain using a variety of instruments that you probably won’t find in your garage. USGS will measure water levels in the Potomac River -- Washington’s sole source of tap water.

As the Mid-Atlantic region continued to experience prolonged dry weather, flow into the Chesapeake Bay and from its three main tributaries dropped to record low volumes for the month of June, according to U.S. Geological Survey hydrologists.

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.
