Danvers supplies water to both Danvers and Middleton customers from sources from within Middleton, including Middleton Pond on Lake Street, the main reservoir; Emerson Brook, which is used to top off Middleton Pond; and two wells along the Ipswich River near the Danvers border.
The Danvers water restrictions are part of the towns’ water withdrawal permit, and were put in place when the state Department of Environmental Protection mandated regulations as part of the state’s Water Management Act. These regulations aim to protect river basins under stress from heavy use. Danvers is part of the highly stressed Ipswich River basin.
Danvers is also under a summer cap for water usage from May 1 to Oct. 1. This cap restricts Danvers to 3.8 million gallons per day, meaning conservation measures now could head off more stringent restrictions later this summer.
“It’s been about average for this time of the year,” Lee said of summer usage. “It hasn’t been unusually high demand.”
The mostly dry July has meant a steep drop in the flow of the Ipswich River, however.
When the river flow falls below 18.7 cubic feet per second at a gauge in South Middleton, water restrictions are triggered.
On July 12, the flow was 37 cubic feet per second, Lee said. On Friday, he said, it had dropped to 9.4 cubic feet per second. This low level also means Danvers cannot pump from its wells.

How to conserve water
Don’t water during the day, as up to half will be lost to evaporation.
Use rain barrels or cisterns to capture water for irrigation.
Let your lawn grow to at least 31/2 inches.
Make sure water flows to your plants and gardens, not down the driveway or into the street.
Don’t feed your lawn during a dry spell. Doing so forces grass to grow, increasing the requirement to water more.
Fix leaky toilets and taps.
Cover swimming pools to prevent water loss from evaporation.
