Monthly Surface-Water Conditions

Streamflows in October 2009 were generally designated as above normal (the monthly average streamflow is between the 76th and 90th percent of the monthly average streamflows for this same month) in Massachusetts and Rhode Island. The exceptions were south central (Chicopee and Thames River Basins) and southwest (Farmington River Basin) Massachusetts, where monthly average streamflows were normal (the monthly average streamflow is between the 25th and 75th percent of the monthly average streamflows for this same month).
This assessment is based on the USGS WaterWatch Current water resources conditions map of monthly-average streamflow for the month of year for 60 near real-time streamflow-gaging stations with 30 or more years of record in Massachusetts (figure 1) and 15 near-real-time streamflow-gaging stations with 30 or more years of record in Rhode Island (figure 2). General surface-water conditions in Massachusetts and Rhode Island by State-designated drought regions are shown in the table 1 and table 2. Surface-water conditions for individual streamflow-gaging stations may differ from conditions shown for a region in tables 1 and 2.

Duration hydrographs that show general streamflow trends over the past two years for selected streamflow-gaging stations with 20 or more years of record are shown in each of the six Massachusetts Executive Office of Energy and Environmental Affairs (MA EOEEA) and Massachusetts Emergency Management Agency (MEMA) Drought Regions. Each region includes one to five streamflow-gaging stations.

Duration hydrographs that show general streamflow trends over the past two years for selected streamflow-gaging stations with 20 or more years of record are shown in five of seven Rhode Island Water Resources Board (RIWRB) Drought Regions. Each of the five regions includes one to four streamflow-gaging stations. No streamflow-gaging stations are operated in the Eastern and New Shoreham regions.
