The primary human-caused impediments to fish passage on small anadromous streams in Southeast Alaska exist at road crossings where culverts and bridges have been improperly installed or damaged throughout time. Restoring fish passage at these crossings is desirable to maintain healthy anadromous fish populations. However, the possibility of restoring all these deficient structures is limited by the amount of restoration and mitigation funding available. This creates a need to prioritize these crossings to maximize the gain in habitat in light of limited monetary resources. To address this, the TWC with assistance from USFWS inventoried 37 culverts in the Haines, Borough. The accompanying map highlights the condition of the road crossing and the extent of anadromous fish.
