Wild salmon are central to the culture, subsistence lifestyle, and ecosystem of the Tebughna people. Many salmon streams in our region are crossed by historical logging roads, industrial access trails, or public infrastructure. Undersized or failing culverts create velocity barriers, perch above water level, or block fish passage entirely. TTCD works with local landowners, Tribal partners, and agencies to restore aquatic connectivity.
Fish Passage & Culvert Replacements
TTCD identifies and prioritizes failing or restrictive stream crossings throughout the District. By replacing undersized culverts with engineered stream simulation structures and wide-span bridges, we restore natural stream width, channel gradient, and sediment transport so juvenile and adult salmon can move freely.
- 60.2 Stream Miles Opened: Reconnected upstream spawning and rearing habitat across multiple Cook Inlet watersheds.
- 13 Culvert Sites Replaced: Engineered fish-friendly crossings that withstand high flow events and ice breakup.
- 500+ Lake Acres Accessible: Restored access to essential overwintering and rearing lakes for Coho and Sockeye salmon.
Upcoming Projects
TTCD continues planning and engineering for high-priority fish passage barrier removals. Projects slated for 2025 include two critical culvert replacements on Roberts Creek to reopen additional upstream spawning habitat.
Watershed Monitoring & Anadromous Waters Catalog
TTCD conducts continuous water temperature logging, stream surveys, and juvenile salmon sampling across district streams. In 2024, TTCD added 18 nominations to the Alaska Department of Fish & Game (ADF&G) Anadromous Waters Catalog (AWC), ensuring regulatory protection for essential salmon habitat.

Salmon Population & Habitat Stewardship
Through community engagement, youth internships, and partnerships with Tribal elders, TTCD combines traditional Dena'ina ecological knowledge with modern scientific monitoring to steward wild salmon populations for future generations.
