  • Notice - The USGS Water Resources Mission Area's priority is to maintain the safety and well-being of our communities, including providing critical situational awareness in times of flooding in all 50 U.S. states and additional territories. Our hydrologic monitoring stations continue to send data in near real-time to NWISWeb, and we are continuing critical water monitoring activities to protect life and property on a case-by-case basis. The health and safety of the public and our employees are our highest priorities, and we continue to follow guidance from the White House, the CDC, and state and local authorities.

USGS 01104430 HOBBS BK BELOW CAMBRIDGE RES NR KENDALL GREEN, MA

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

LOCATION--Middlesex County, Hydrologic Unit 01090001, on right bank, 50 ft downstream of culvert at Winter Street, 300 ft downstream of gate house outlet from Cambridge Reservoir, and 1.3 mi north of Kendal Green.
DRAINAGE AREA--6.86 mi2.
PERIOD OF RECORD--July 1997 to current year.
GAGE--Data Collection Platform, water-temperature and specific conductance monitor, air temperature monitor, and a heated tipping-bucket precipitation gage equipped with a wind shield. Elevation of gage is 150 ft above sea level (from topographic map). Telephone telemeter at station. Datum of gage is referenced to the City of Cambridge datum, subtract 10.84 feet to elevations to adjust to National Geodetic Vertical Datum of 1929. Dissolved chloride and sodium concentrations estimated from specific conductance measurements using the regression technique described in Smith 2013.
REMARKS--Flow affected by regulation of dam 300 ft upstream at outflow of Cambridge Reservoir.
COOPERATION BY--Cambridge Water Department

Daily and unit values precipitation data are calibrated and quality assured prior to publication by the Massachusetts-Rhode Island Water Science Center. Data are available upon request.
