MDMR & NOAA Argue for Fish Passage Performance Standards
It is not enough to simply build a fish passage structure. It has to be effective at moving fish across a barrier. For example, the fish ladder at the Brunswick dam was built almost 50 years ago and even though hundreds of thousands of fish arrive at its base, only a tiny fraction pass above the dam. Experts from MDMR and NOAA have studied necessary performance standards for fish passage and have recently published the following recommendations.
