I have never heard of it. I did a google search and only found out about Wetaboo the indian princess, no reference to ships or wrecks.
A few years back we did the dive below. We were not impressed, good visibility, but nothing to see, a few old timbers. In fact in the whole hour underwater we saw one fish. Or as my dive buddy describes good visibility in a lake, you can see nothing from further away.
Blodgett's Landing, Lake Sunapee
Location: Four miles north of Newbury, N.H., on Route 103A. Watch for a sign marking the left-hand turn to the landing.
Special Features: The 90-foot steamship Edmund Burke burned to the waterline and sank here in the 1930's. Its remains lie in shallow water in front of the only cottage located between the road and the lake. Divers occasionally find anchors and fishing tackle at this site as well as old bottles from the settlement's early days.
Access: Walk across beach or down boat ramp.
Hazards: None.
Depth: To 25 feet near shore, to 100 feet further out in the lake.
Currents: None.
Parking: Small lot on the left at the bottom of the hill.
Restrictions: None.
