Lake Winnipesaukee conditions: how to use this page

This page combines a matched USGS lake monitoring location with National Weather Service data near Lake Winnipesaukee in New Hampshire. A missing value does not mean the lake has no level or temperature information; it means the matched public sensor did not return a usable current reading through the source used by Lake Conditions Lab.

Water level and temperature can vary by gauge location, sensor depth, wind, inflow, dam operations and weather. Use these readings for trip planning, then follow posted notices, marina guidance and local authorities for on-water decisions.

The USGS monitoring record associated with this page lists a drainage area of approximately 363 square miles. This is station metadata, not the lake's surface area.
