Description

With construction of the Lock and Dam 4 dike, fresh water flows could only enter the Finger Lakes overland during high water.  This caused low dissolved oxygen conditions in the lakes at other times of the year, hampering fish productivity.  The Corps of Engineers installed a culvert through the dike in the 1960’s to provide flow to one of the lakes.  The other four lakes continued to experience periods of low dissolved oxygen during the summer and winter.
