Precipitation was above normal at all three index stations. Newark reported 6.79 inches, which is 215 percent of normal. Atlantic City reported 6.38 inches, which is 223 percent of normal. Trenton reported 5.02 inches, which is 192 percent of normal.

Combined storage in the thirteen major water supply reservoirs as of October 31 was 55.4 billion gallons, which is 68.9 percent of capacity. The storage was 8.2 billion gallons more than one month ago and 15.4 billion gallons more 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.
