Map of the watershed (Water Intelligence Platform)

The map below, from the Water Intelligence Platform, displays all permitted withdrawal locations (groundwater- yellow, surface water- red, other-purple). These facilities withdrawal 100,000 gallons per day or more. It is important to note that almost all of the withdrawals are groundwater withdrawals. The assumption being made for ‘altered flow’ calculations is that groundwater withdrawals are removed from the stream (1-to-1), as if they were surface water withdrawals. Therefore, this is likely a poor representation of flow alteration.

Streamflow

Below is a monthly hydrograph (1960-2010) of the observed streamflow (cfs) at the Cohocton River gage near Campbell, NY. This USGS gage was used as the reference gage to estimate natural flows at the location of interest. A hydrograph of these estimated flows are displayed in the blue hydrograph below.

A monthly flow duration curve of natural and altered estimated flows is displayed below.
