Residents and businesses who get water from the Lamprey River watershed are being asked to conserve water until higher flows return. Warm weather and limited rainfall are causing low flow levels. The request covers the communities of Durham, Lee, Epping, Raymond, Candia, Deerfield, Northwood, Barrington, Freemont, Newfields and Newmarket, all of which can affect stream flows in the 50-mile Lamprey River.
