Flood Impacts & Photos Collapse

25 Comparable to the FEMA 0.2 percent flood level. Record flooding similar to the Flood of 1923. Transportation across the area will be severely impacted. Several portions of US Route 2 flooded and impassable between West Enfield and Milford.
23 Comparable to the FEMA 1 percent flood level.
22 Closure of Route 2 likely between Greenbush and Milford. Flooding on US Route 2 can occur along the confluences with the Sunkhaze Stream or Costigan Brook in Milford, and the Boonridge or Stevens Brook in Greenbush due to backwater effects.
21 Flooding on US Route 2 in Milford at the Greenfield Road to Bo's Lane. There will be an expansion of minor flood impacts from local streams caused by increasing backwater effects.
20 High flows on the Penobscot River cause backwater effects upon several streams and creeks resulting in lowland flooding between Greenbush and Milford. Properties along the Penobscot River could have impacts on outbuildings.
18 River is out of banks in several areas with high flows. Residents along the river should prepare for flooding if additional rises are expected.
16 River approaches bankfull.
