The Forest System’s Aquatic Organism Passage (AOP) program is funded through the Safe, Accountable, Flexible, and Efficient Transportation Equity Act Legacy for Users (SAFETEA-LU) with HTAP (Highway Trust Funds for Aquatic Passage) funding. The Forest Service’s engineering division oversees this program currently funded at $10 million a year, to retrofit and replace road crossings that are barriers to fish and other aquatic organisms. In 2010, the $10 million HTAP program funded 62 projects that opened more than 270 miles of stream and river to fish passage, and supported important regional barrier assessments, training and monitoring. This presentation will review the accomplishments of the HTAP program, the valuable contribution of partners, and opportunities for this integral funding program to expand AOP across National Forest System lands.
