REMARKS - Records of discharge for the 2010, 2011, 2012, 2013 and 2014 water years are not published due to gates remaining open for extended periods of time. Discharge could not be determined during this condition. Flow can be regulated by four vertical lift gates, two on either side of control weir. New control weir constructed in 1991. Records of discharge for water years 1999-2005 represent only flow over the top of the weir. Daily value discharge during water years 1999-2005 are not provided when partial or full gate openings occurred. Records of discharge prior to water year 1999 include combinations of flow over the weir and gate flow. No distinctions in flow types prior to water year 1999 have been made. Zero flow occurs numerous days, during all water years.
