Water-Year
Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
USGS Water-Year Summary 2024
01125500 QUINEBAUG RIVER AT PUTNAM, CT
LOCATION - Lat 41°54'34.11", long 71°54'49.91" referenced to North American Datum of 1983, Windham County, CT, Hydrologic Unit 01100001, on right bank at Putnam, 0.15 mi downstream from Little River, 0.3 mi upstream from New York, New Haven and Hartford Railroad bridge, 2.8 mi downstream from French River, 3.0 mi downstream from West Thompson Dam, and 36 mi upstream from mouth.
DRAINAGE AREA - 328 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - Discharge: December 1929 to September 1969, October 1995 to current year. Monthly discharge only for October and November 1929, published in WSP 1301. Stage record only October 1974 to September 1995.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 216.76 ft above National Geodetic Vertical Datum of 1929. Prior to Aug. 1, 1958, at same site on left bank at same datum. Satellite telemetry at station.
REMARKS - Water Year 2018 - 2022: Records good except for periods of estimated discharge, which are fair.
Water Year 2014 - 2017: Records good except for periods of estimated daily discharges, which are poor.
Peak flows are affected by flood-control regulation at East Brimfield Lake, Westville Lake, West Thompson Lake, Hodges Village Reservoir, and Buffumville Lake since 1960. The natural flow regime is altered by regulation at East Brimfield Lake, Westville Lake, West Thompson Lake, Hodges Village Reservoir, Buffumville Lake, Lake Chaubunagungamaug, Quaddick Reservoir, and other small reservoirs in the basin.
EXTREMES FOR PERIOD OF RECORD - The maximum peak flow of 48,000 ft³/s was obtained from rating curve extended above 2,500 ft³/s on basis of computation of flow over dam at gage heights 17.28 and 19.45 ft and slope-area measurement of peak flow. The maximum peak stage of 26.50 ft. was from flood marks.
WATER-QUALITY RECORDS
PERIOD OF RECORD - Chemical analyses available for water years 1955, 1957-1960, 1962, 1970, 1972, January, 1999 to September, 2007.
