The purpose of the hearing, which will be held virtually, is to seek input from interested parties as the Commission considers declaring a “water supply emergency” if conditions worsen.
A special DRBC business meeting on the issue will be set on or after November 21.
“Many areas in the Delaware River Basin continue to experience significantly below-normal precipitation with resulting effects on streamflows, groundwater levels and reservoir storage,” said Tambini. “These conditions have already prompted the states of New Jersey, New York, Delaware and Pennsylvania to declare drought watches or warnings in most or all of the counties that lie within the Basin.”
Beginning in October, low flows in the Delaware River prompted the DRBC to direct releases of stored water from a federal reservoir, Beltzville (Carbon County., Pa.) to meet the minimum flow objective for the river at Trenton, N.J. “As of 8 a.m. today, approximately 1.12 billion gallons (BG) of water has been released from Beltzville Reservoir to meet the Trenton Flow Objective,” said Amy Shallcross, DRBC’s Water Resource Operations Manager. An additional source of water in the lower basin that is available for use to meet the Trenton Flow Objective is Blue Marsh Reservoir (Berks Co., Pa.).
Salt Front
The purpose of the Trenton Flow Objective is to control the “salt front” in the tidal Delaware River.
Freshwater is needed to keep salty or brackish water from advancing up the Delaware Bay during low-flow conditions and reaching drinking water intakes for Philadelphia and New Jersey communities, and industrial intakes along the river.
“The salt front is currently 17 river miles upstream from its normal location for this time of year despite the reservoir releases,” said Shallcross. “If more water is needed to address salt front management, we expect continued decreases in reservoir storage and additional drought risks.”
Unless precipitation trends change in the near term, initial drought management actions are reductions in flow objectives for the main stem Delaware River and out-of-basin diversions to conserve reservoir storage.
In a drought emergency, the drought plan gives the DRBC the authority to call for releases from additional reservoirs to increase river flow.
The Basinwide drought management plan is based on the amount of combined storage in the three New York City reservoirs, the largest in the Delaware River Basin.
As of 8:00 a.m. November 6, the combined storage in NYC’s Delaware River Basin reservoirs is currently 38 billion gallons above the level that initiates a drought watch.
The low storage is in part due to NYC’s Delaware Aqueduct Repair Project. NYC is not currently diverting water from the Delaware River Basin reservoirs while the repair is being made.
The public is encouraged to visit the NYC Department of Environmental Protection website for updates on the Delaware Aqueduct repair project.
Curb Water Use
The DRBC is also urging all water users to voluntarily curb water use in Basin communities where drought watches and warnings have been issued, maximize water efficiency and cooperate with all state-issued alerts.
“Over 14 million people rely on our shared waters, and while we may believe this resource is limitless the fact is that we never know when the next long-term drought might begin. Collectively we can work toward improving water efficiency every day, not only when we experience dry conditions,” added Tambini.
