Carrie Banks Riverways Adopt-A-Stream Program Massachusetts Department of Fish & Game River Health 101: Shoreline Survey Training for Stream Team Volunteers
A Stream Crossing is anywhere a road, railway, driveway, path, etc crosses a river or stream. The goal of the surveys is to determine what impact these crossings have on fish and wildlife
Imagine this is Brookie’s watershed that she covers in any given year. Moving around for spawning, feeding, visiting the neighbors, hiding from high flow events or seeking a cool spot to hang out in.
Brookie’s movements in the watershed would be restricted and she would be cut off to vital habitat areas she may need to utilize in her life time
Inlet or Outlet Drop Physical Barriers Debris Accumulation Excessive Velocities Absence of Bank Edge Areas Flow Contraction (Turbulence) Insufficient Water Depth Discontinuity of Channel Substrate
As a reminder of why we care so much about small streams!
It was replaced with a bottomless arch culvert with a 40-foot span across the river channel. The natural streambed mimics the substrates, flows, and depths of the surrounding stream. In addition, a low-flow channel is able to naturally form.

Stream Crossings Where roads and railways cross rivers and streams Over 900 stream crossings have been identified in the Housatonic Watershed in Massachusetts
It’s not only fish that may havedifficulty moving through crossings
Wildlife can be impeded from using thecrossing due to a variety of culvert problems
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
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
Replacement• Replace culvert with: • 1. Bridge • 2. Oversized (1.2 bankfull width) culvert with river substrate
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 firstname.lastname@example.org.Keep building beautiful bridges that allowfree passage
