Summary of November 2004 Monthly Hydrologic Conditions

Compiled in cooperation with the New Jersey Department of Environmental Protection
Provisional assessment of hydrologic conditions in New Jersey

The following pages are adapted for online release from a summary of hydrologic condions for the previous month.

November 2004

Precipitation was above normal at all three index stations. Newark reported 4.37 inches, which is 113 percent of normal. Atlantic City reported 4.42 inches, which is 136 percent of normal. Trenton reported 4.54 inches, which is 136 percent of normal.

Combined storage in the thirteen major water supply reservoirs as of November 30 was 76.2 billion gallons, which is 94.8 percent of capacity. The storage was 1.93 billion gallons more than one month ago and 3.29 billion gallons less than one year ago. The thirteen major water supply reservoirs are as follows: Lake Tappan, Woodcliff Lake, Oradell Reservoir, DeForest Lake, Splitrock Reservoir, Boonton Reservoir, Canistear Reservoir, Oak Ridge Reservoir, Clinton Reservoir, Charlottesburg Reservoir, Echo Lake, Wanaque Reservoir and Spruce Run Reservoir.

Streamflow was above normal at all three index stations. The monthly-mean discharge at South Branch Raritan River near High Bridge was 130 ft³/s, 107 percent of normal. The monthly-mean discharge of the Great Egg Harbor River at Folsom was 94.0 ft³/s, 122 percent of normal. The observed monthly mean discharge of the Delaware River at Trenton was 12,440 ft³/s, 113 percent of normal. The observed daily mean discharge of the Delaware River at Trenton on November 30 was 55,800 ft³/s.

Groundwater levels, as measured in water-table observation wells, were above normal, and increased from last month at all three index stations. Compared to one year ago, levels were lower at Readington School 11, slightly lower at Vocational School 2, and slightly higher at Morrell 1.

Water quality parameters collected from the Delaware River at Trenton were within recorded historical monthly extremes. Water temperature ranged from 5.9 to 13.1 degrees celsius. Dissolved oxygen ranged from 9.9 to 15.8 milligrams per liter. Specific conductance ranged from 80 to 219 microsiemens per centimeter at 25°C.
