What’s New

  • Request for Proposals & Qualifications for the Hydrologic Assessment of Reservoir Brook, Meredith, NH
  • CALL TO ACTION! – Powder Mill Fish Hatchery Discharge Permit Merrymeeting Lake outlets into Merrymeeting River which flows through New Durham into Lake Winnipesaukee at Alton Bay. Merrymeeting Lake provides the Powder Mill State Fish Hatchery (PMSFH) with 7 million gallons of fresh water per day. The water leaving Merrymeeting Lake has an average phosphorus concentration of 5 µg/L while the PMSFH withdraws and discharges a near-constant water load containing phosphorus levels approximately 12 times higher than the outflow concentration from Merrymeeting Lake. PMSFH has been operating on an expired USEPA discharge permit since 2016 and NH Fish & Game has requested a new discharge permit. The EPA has given October 1 as their estimated time to publish a draft permit in the Federal Register. To learn more about this issue and see how you can help, click here.

Help Keep Winni Blue – Put a Sock In It!

1 qt decal
Proper boat maintenance protects our lake.  Oil and fuel can leak from your engine and collect in the bilge compartment.  When the bilge is activated, these chemicals are discharged into the lake.

Bilge socks, which absorb the excess oil and gas, are an inexpensive way to prevent these substances from polluting our water.

Install a bilge sock into your engine’s compartment at the beginning of the boating season, and remove and dispose of it during the winterization process of your vessel.  You can request your marina to do it, or do it yourself.  You should check the bilge compartment on a regular basis to be sure the sock is properly secured.

  • Use proper care when fueling your boat – do not top off your tank.
  • Do not wash your boat in the lake – only at an approved wash station, or away from the lake.
  • Use nontoxic, and chlorine and phosphate free cleaners.
  • Use Pump Out Stations – it is illegal to discharge untreated sewage into the lake.
  • Clean, drain, and dry your boat when trailering to help prevent the spread of invasive species from one waterbody to another.
