Aquatic Organism Passage Program Reporting, Guidance, and Directives

Annual Reporting Requirements

Projects funded with Forest Service fish and wildlife funds, and/or with other fund sources are reported in the Wildlife, Fish, and Rare Plants database, which is available to the public at the USDA Forest Service Watershed, Fish, Wildlife, Air, and Rare Plants website.

Projects funded primarily through the Legacy Roads and Trails Restoration program (CMLG) are reported to the Forest Service Engineering Staff.

The status of AOP projects funded by the Safe Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), referred to as “HTAP” projects, for “highway transportation act projects”, are reported annually to the Federal Highways Administration (FHWA).

The implementation results of aquatic organism projects are reported under the Forest Service’s accountability system as:

  • Stream Miles Restored/Enhanced
  • Lake Acres Restored/Enhanced
  • Number of Structures replaced for AOP
