Subj: New major flood stage level and updated impact statements
for the stream gauge at Waterbury, VT on the Winooski River.
Effective at approximately 0900 UTC Coordinated Universal Time on
Tuesday, October 17, 2023, the NWS in Burlington will lower the
major flood stage level from 428.0 feet to 425.0 feet for the
stream gauge at Waterbury, VT on the Winooski River. The levels
for minor and moderate flood stage (419.0 and 421.0 feet,
respectively) will remain unchanged. Those are shown below for
reference.
This change is a result of recent flood damage assessment surveys
performed in the region during which a re-evaluation of the local
floodplain within the stream gauge reach was coordinated with
local town officials. In addition to the new major flood stage
level, updated wording will be incorporated into impact statements
at moderate, major and record flood levels. Those are also shown
below for reference, which will provide added situational
awareness to local citizens and emergency responders during future
flooding events.
