  2. 2. Stream Crossings Where roads and railways cross rivers and streams Over 900 stream crossings have been identified in the Housatonic Watershed in Massachusetts
  3. 3. It’s not only fish that may havedifficulty moving through crossings
  4. 4. Wildlife can be impeded from using thecrossing due to a variety of culvert problems
  5. 5. Importance of Small Streams• Make up a large percentage of stream miles• Cumulatively provide more habitat than large rivers• Support species not found in larger streams and rivers• High productivity• Provide important spawning & nursery habitat for fish
  6. 6. Impacts of Sub-Standard Crossings• Habitat loss and degradation• Alteration of ecological processes• Road kill leading to population losses• Population fragmentation and isolation• Reduced access to vital habitats• Disruption of processes that maintain regional populations
  7. 7. Replacement• Replace culvert with: • 1. Bridge • 2. Oversized (1.2 bankfull width) culvert with river substrate
  8. 8. What can SAM do ?1. Alert us to any crossing concerns2. Obtain GPS coordinates for that location3. Take upstream and downstream pictures ofthe crossing (INLET and OUTLET)4.Send pictures and coordinates toadixon@hvatoday.org5.Keep building beautiful bridges that allowfree passage
