Description: The Little Susitna weir located at river mile 32.5 will not be operated in 2025. High water has caused substantial damage to the weir in recent years, so alternative assessments will be explored. The primary assessment for Chinook salmon will be aerial survey index counts, and a new sonar project will be tested for feasibility. The weir will be moved this summer to river mile 39.5, a site that is wider and shallower, which combined with improvements to the weir design should provide a more durable assessment. This new weir is planned to be operational for counting coho salmon in 2025 and those counts will be available on this page.
Sustainable Escapement Goal for Chinook:
