Stream Crossings

Repairing stream crossings in Maine is an investment in our communities, economy and way of life.

A proposed $5 million bond would help fund improvements of our road infrastructure (stream culverts). This will improve public safety by preparing for extreme flood events and benefit Maine’s wildlife by reconnecting fish and wildlife habitat. Many of our existing culverts are currently blocking fish passage. Stream connectivity is critically important to maintaining healthy fish and wildlife populations. With good stream connectivity, fish are free to move upstream or downstream. Improvements for fish also support the health of other wildlife in the ecosystem.

Many Maine culverts are old, ineffective, and put roads, public safety, and wildlife at risk.

  • Much of our water infrastructure, including the culverts that allow streams to pass under roads, were put in place during the World War II era or even earlier.
  • Old culverts can get blocked or fail entirely, creating a public safety hazard and cutting fish and wildlife habitats into separate, isolated segments.
  • Surveys show that up to 90% of culvert crossings make movement difficult or impossible for wildlife at least part of the year, while nearly 40% are severe barriers for wildlife movement.
  • Habitat fragmentation can result in the loss of species including highly-prized fish species like Eastern brook trout and Atlantic salmon.

Stream connectivity is critically important to maintaining healthy fish and wildlife populations.

  • With good stream connectivity, fish are free to move upstream or downstream – from the smallest stream to the ocean or lake – allowing fish to find the appropriate water type and temperature to spawn, grow and stay healthy throughout their lifecycles.
  • Maine’s identity and our economy depend on our natural resources. Business leaders know that our coast, rivers, streams, lakes and ponds provid
