This information is being provided as a service for those who are interested in the river level in the City of Jefferson.  

Per DNR mandate, the City of Jefferson must maintain the river level between a minimum headwater of 782.0 and maximum headwater of 783.0.  (United States Geologic Service (USGS) Elevation).  There is a corresponding gauge on the Rock River Dam in the City of Jefferson used to measure the water level. 

Gate adjustment is determined by headwater elevation and flowage upstream.  For more information on upstream water levels and flow Click Here.
