..REMARKS..
Passumpsic River Saint Johnsbury 44.42N -72.01W
Caledonia County VT NWS surveys
Jam is located at the confluence of the Passumpsic and
Moose Rivers in St. Johnsbury, and likely formed during
the ice breakup event of Dec 18-20, 2025. This is a
common location for jams to form as there are
significant shoals at this location. Water is finding a
way around the jam, but the quantity of jumbled and/or
rafted ice will need to be monitored during ice breakup
later this winter/spring.
None observed
Passumpsic River Lyndonville 44.55N -71.99W
Caledonia VT NWS surveys
This is a small jam centered around the Lily Pond Road
crossing of the E. Branch of the Passumpsic River in
Lyndon, VT. This is a common location for ice to jam up
due to the shallow nature of the channel at this
location, and in the past has served as source ice for
additional jamming downstream during breakup. Water is
finding a way around the jam currently, but conditions
will need to be monitored during breakup later this
winter/early spring.
None noted
Lamoille River East Georgia 44.68N -73.08W
Franklin County VT NWS surveys
This is a small ice jam on the Lamoille R. at the
entrance to Arrowhead Mountain Lake. Water is finding a
way around the jam at this point. This is a common
place for jams to form as the river current slows upon
entry into the upper lake waters. In general, the jams
at this location pose little threat to property, with
the only real issue here is possible minor flooding
along Arrowhead Lake Rd.
Salmon Whippleville 44.79N -74.25W
Franklin County NY NYS Watch Ctr.
Large ice jam on the Salmon River south of Malone, NY
near the hamlet of Whippleville. Specifically, this
along a bend in the river just north of the Kimpton
Bridge and is approximately 1/4 mile long. No flooding
is occurring, but county EM has brought in excavators
to help alleviate/clear ice and is concerned as this is
a large jam. Drones were also flown over the jam, but
not sure if imagery is available.
None at this time.
