Beaver Lake in Derry, New Hampshire operates under specific speed restrictions that impact paddling conditions. State regulations limit boat speeds to 10 mph except between 1:00 p.m. and 7:00 p.m. daily, when speeds up to 30 mph are permitted. All water skiing must follow a counterclockwise direction. Personal watercraft (skicraft) have been banned on the lake since October 7, 1999.

Yellow perch and pickerel thrive in the lake's waters, offering opportunities for paddlers who enjoy fishing. The lake maintains sufficient depth and water quality to sustain these game fish populations.

The lake is subject to mixed use, with both motorized and non-motorized vessels sharing the water. Paddlers should be particularly aware of increased boat traffic and higher speeds during the afternoon hours when speed restrictions are lifted. Morning hours, before 1:00 p.m., typically offer calmer conditions more suitable for paddling due to the enforced speed limits.

Due to the dual-speed regulation system and the mixing of motorized and non-motorized craft, paddlers should maintain awareness of other vessels and consider wearing high-visibility clothing. The established counterclockwise traffic pattern for water skiing may help paddlers anticipate and avoid conflicts with powered craft.
