Officials at one of New Jersey’s reservoirs say that the state could potentially face a drinking water crisis if the state does not get more rain soon.

Officials with the North Jersey Water Commission say that despite the recent blizzard and subsequent snowmelt, the levels at the reservoirs are dangerously low. They says that Wanaque and Monksville Reservoirs are at 45.6 percent combined. For perspective, when New Jersey was under a drought warning last year the levels were at 69 percent.

Officials say that a lack of rain this winter is the cause of the low levels.

The water commission has been pumping water from nearby rivers and lakes since November to compensate. But the levels of those bodies of waters are also low.

New Jersey is expected to see rain Thursday night into Friday. But officials say that while it will help, the state needs a stead amount of rain for a period of time to get the levels back to normal.
