Water use in Rochester, Dover may be harming river

The cities of Rochester and Dover are withdrawing too much water from the Isinglass River and not properly putting enough back in, state environmental officials say.

Dover avoids withdrawals during periods the state identifies as having low flows, but Rochester has diverted water during such times. One local official says the city is willing to work with the state, but isn't convinced the withdrawals are a problem.

The state in recent years on the Seacoast has recorded withdrawals above standards from the Isinglass, Exeter and Lamprey rivers. Withdrawals from the Isinglass were above standards during all of 2003 and 2004, while the others were above primarily in summer months.

Excessive withdrawals could lead to low river flows resulting in water shortages and environmental harm.
