Restrictions on outdoor water usage in Danvers have been lifted. The town on Oct. 1 shifted to Level 1 of its water restriction policy. Under Level 1, which is typically in effect from Oct. 1 to April 30, there are no limits on water use. Following state regulations, the town moves to higher water restriction levels between May 1 and Oct. 1 when water flow on the Ipswich River drops below specified thresholds. The state adopted the regulations, which apply to all communities that draw water within stressed river basins, as a way to protect those rivers. The two wells and two reservoirs that Danvers uses for its water supply — which also serve Middleton — are all located in the vicinity of the Ipswich River.
