Report of the River Master of the Delaware River for the period of December 1, 1980 to November 30, 1981
Water supply conditions at the beginning of the year were marginal in marked contrast to those for the preceeding nine years. Discharge of the Delaware River at Montague, New Jersey, was only 72% of median as compared to 68% in excess of median the previous year. In December, with reservoir storage again declining, further reductions in both diversions and releases were imposed. With consent of all the parties, reductions were effected on December 20 limiting New York City diversions to 560 mgd, New Jersey to 65 mgd, and the required discharge at Montague was targeted at 1550 cfs. To conserve supplies, additional reductions were imposed in January when the Delaware River basin Commission formally declared a drought. New York City 's limitations was set at 520 mgd and that for New Jersey at 62 mgd. Montague flows were targeted between 1100 cfs, depending upon the location of the salt front in the estuary. Water quality of the Delaware River and Estuary was monitored on a continuous basis at eight sites for most of the year and on a monthly basis at ten sites to accurately locate the salt front. Highest concentrations observed at the Benjamin Franklin Bridge site was 133 mg/l (milligram per liter) on February 2. (USGS)
