Lake safety Issues

Boating Safety

Please observe all rules and regulations as required by NH State law.  Deering Lake is enjoyed by swimmers, kayakers, canoeists, fisherman, and boaters.  All motorized watercraft must maintain headway speed when within 150 feet of shore, other boaters, and non-motorized watercraft. Ski crafts are prohibited on Deering Lake.

Objective: To create an environment of safe and courteous use of the lake that will ensure maximum enjoyment of the lake for all, boaters and non boaters. All persons using the lake are asked to be respectful of the rights of others and adhere to common sense rules of courtesy when on or near the lake.


  • Watercraft should not be operated in a reckless or negligent manner or under the influence of drugs or alcohol.
  • Boats should not be operated at speeds in excess of 40 mph and common sense rules of etiquette should be applied at any speed.
  • Swim floats and moorings must be kept within 50 feet of shore.
  • Skiers should not be launched from, nor be returned to, any beach, raft or docking area.
  • Any activity requiring the use of motor boats at high speeds, including skiing and tubing should be limited to periods after 8 a.m. and before 7 p.m.
  • Motorized boat users are asked to always be conscious of damage that may be caused by their wake either to shoreline or other boaters.
  • Clearance between watercraft, people, docks and moorings should be maintained at a minimum of 100 feet or more.
  • Non motorized boats have the right of way at all times, but all boaters should be aware of other boats and the paths they may take; always try to avoid an unsafe condition.
  • From sunset until sunrise watercraft must use running lights, lanterns or flashlights.
  • "Cover boats" should accompany all persons swimming more than 100 feet from shore.
  • Scuba divers should dive only with a partner and marker buoy.
  • Rules of etiquette for slalom course usage as practiced by the USA Water Ski Association require that skiers approaching a slalom course wait outside the course, at minimum wake, until those using the course have indicated that they are leaving the course.
  • Boats and trailers used in other lakes shall be thoroughly cleaned (propellers, bottoms, bait wells, etc.) before launching into the lake to avoid transference of harmful plants and marine life into the lake.
  • Never release plants, fish or animals into Friends Lake unless they came out of that lake.
  • Do not feed ducks. Ducks cause swimmers itch.
  • Boat drivers under age 18 are required by law to have completed a boating safety course and obtained a State Certificate. (Boating Safety Course).
  • Dumping of any waste, litter, garbage, fuel, oil or sewage into any lake is unlawful.

We ask that all residents, guests and renters adhere to the above guidelines and rules to create an atmosphere of safe and friendly usage of the lake for all concerned.

About Milfoil

These species are not native to our state and is very difficult to control once it becomes fully established. Milfoil reproduces through fragmentation whereby plant fragments break off from the parent plant through wind or boat action, grow roots, and settle in a new location. Milfoil spreads rapidly and displaces beneficial native plant life. It makes swimming difficult and can devalue waterfront property. Where this species grows in its native environment, insects and fish may feed on this plant at such a rate as to control its growth. Milfoil has no natural predators to keep its population in check. Under optimum temperature, light and nutrient conditions, milfoil may grow up to an inch per day. How Did Exotic Milfoil Become Established in This State? It was most likely a "stowaway" fragment attached to a boat or trailer that came to this region. Milfoil can live out of water for many hours if it remains moist.
