Management implications

Specific measureable objectives
Determine stock status of native salmonid populations upstream of Hellís Canyon Dam, focusing efforts in drainages where data is lacking.

Determine factors responsible for the decline of weak stocks.

Develop and implement recovery plans that will remove threats from weak stocks, thus allowing natural rebuilding of those stocks.

Testable hypothesis
Native salmonid populations have not been impacted by human activities.

Underlying assumptions or critical constraints
We are assuming that hydropower developments are a major threat to the existence of native salmonids. We are also assuming that declines in native salmonid populations can be reversed.

A combination of snorkeling and electrofishing will be used to estimate population sizes, age structures, and fish assemblage structure. Habitat surveys will follow the guidelines of Platts et al. 1983 and 1987. Multivariate statistics will be used to relate habitat variables and condition to population size and structure. The focus of the project will be native salmonid populations (bull trout, cutthroat trout, and redband trout) in the Snake River and tributaries upstream of Hellís Canyon Dam.

Brief schedule of activities
1997 - Develop a detailed experimental design and work plan with the cooperators. Conduct a literature search to determine where data is lacking. Begin implementing field work.

1998-2001 - Implementation of the project with field work and data analysis.

Biological need
In order to better manage our fisheries, we need to know the stock status, populations trend, causes of declining populations or threats to long term existence before corrective action or mitigation can occur. Most of Idahoís native salmonid populations are weak. This project will investigate avenues for recovery. In order to strengthen these populations we need to know the underlying causes for their declines.

Critical uncertainties
Factors limiting population sizes in a wide variety of streams and habitats.

Summary of expected outcome
The expected outcome is that we will have on the ground activities that will reduce or eliminate threats to the existence of native salmonids in the upper Snake River basin. These activities may include (but are not limited to) habitat improvement, changes in hydropower operations, diversion screening, protective fishing regulations et al.

Dependencies/opportunities for cooperation
This is a multi-agency project that will be coordinated with and responsibilities shared among IDFG, the Sho-Ban tribes, Sho-Pai tribes, ODFW, and the Burns - Paiute tribe.

We will not be able to identify the limiting factors.

Monitoring activity
Snorkeling and electrofishing will be used to monitor populations responses to mitigation/management efforts. Periodic (once every 2 or 3 years) habitat surveys will be conducted to monitor changes in physical habitat.
