Lake Winnipesaukee Steamer Wreck Valuables

Lost Treasure NH • Belknap County County
Description
Belknap County legend of passenger steamers and cargo boats lost on Lake Winnipesaukee with valuables still in the depths — a lake-wreck tradition centered on the Laconia and Weirs Beach shipping era.
Historical Notes
Lake Winnipesaukee served nineteenth-century steamboat tourism and lumber shipping across Belknap County. Compiled New Hampshire guides credit multiple wrecks with recoverable coins, cargo, and passenger valuables on the lake bottom. Modern scuba surveys document sunken hulls; treasure lore persists around Weirs Beach and the Broads.
Status / Verification legend — Legendary or approximate
