Branch Brook Stream Guage

The District recently received a $20K grant from the Maine Geological Survey to install a USGS stream gauge to monitor the flow rate on Branch Brook.  The gauge records continuous brook flow (cubic feet per second) and level information.

Since the gauge is upstream of the District’s Filtration Plant, a conversion must be done to determine the flow at our Plant.  To convert from cubic feet per second (cfs) to millions of gallons per day (mgd), multiply by 0.646.  For example, a 30 cfs recorded flow rate at the gauge equals 35.4 (30 x 1.18) cfs at the Plant which In turn equals 22.9 (35.4 x 0.646) mgd.
