Full Channel Width Fish Passage SolutionsFort Goff Bridge

Upstream and downstream of barrier outside of any resulting facility scour, take two measurements of established channel widths.

For example:

  • Upstream: 22 feet and 19 feet
  • Downstream: 24 feet and 23 feet
  • The average of the widths is 22 feet.
  • 1.5 (22) + 5 = 38 feet
  • A full-span solution would be 38 feet or greater. Anything less is a partial, hydraulic solution.
