New Jersey Drinking Water Supply Indicators

With below average rainfall remaining the dominant weather pattern, which has impacted streamflow, groundwater, and water supply reservoirs, the NJDEP has declared a statewide Drought Watch. 

New Jerseyans are asked to follow water conservation practices.

Droughts and Climate Change

As outlined in the recently adopted 2024 New Jersey Statewide Water Supply Plan, New Jersey is experiencing the impacts of climate change on water supply. Recent years have shown a trend of increasingly intense rainfall events followed by periods of little or no rain. With the increased uncertainty posed by these weather patterns, it can become challenging for water supply managers to ensure the availability of water resources during dry periods.

October 21st Drinking Water Supply Update

Approximately .25 - 4.11" of rain were observed during the last week. Our region's 90 day Precipitation was downgraded to Extremely dry, and our 90 day stream flow is Severely dry. Our Unconfirmed groundwater has been downgraded to "Emergency" level.

The DEP continues to closely monitor drought indicators – which include precipitation, stream flows, reservoir levels, ground water levels, and water demand – and will continue to inform the public, local governments, and water systems of future actions to mitigate the risk of more severe conditions. Municipalities or water utilities may require additional restrictions depending upon local water supply conditions.
