Short description | Collect time series information to examine migrational characteristics of wild ESA-listed Snake River spring/summer chinook salmon stocks. PIT tag wild chinook salmon parr annually; and subsequently monitor as smolts at stream traps and river dams. |

Year | Accomplishment |
1992 |
From 1992 to 1999, annually documented migrational timings of individual and combined populations of wild Snake River |
|
sp/sum. chinook salmon smolts at dams. In each year, migrational timings of these wild fish populations at traps and dams |
|
were used for real-time management of the hydropower system operations and water budget usage. |
1993 |
From 1993 to 1996, worked with Pacific Northwest National Laboratories to established water quality environmental monitoring in several streams where wild chinook salmon parr are PIT tagged for this project. |
1996 |
Took over all environmental monitoring in natal rearing areas of several streams where wild parr are tagged. |
1997 |
Established a database of environmental data from streams on the Internet. |
1998 |
Started examining relationships between movements of wild chinook salmon parr/smolts out of natal rearing areas (through stream traps) to several water quality parameters measured concomitantly by the environmental monitors. |
Objective | Task | Duration in FYs | Estimated 2001 cost | Subcontractor |
1. Assess the migrational characteristics of wild Snake River spring/summer chinook salmon smolts at lower Granite Dam. |
a. Mark with PIT tags wild chinook salmon parr in selected streams above Lower Granite Dam. |
|
$189,200 |
|
1.
|
b. In Spring 2002 intercept and automatically decode previously PIT-tagged smolts at Lower Granite Dam. |
|
$27,000 |
|
2. Determine migration timing differences between and within years for individual wild stocks and combined wild stocks at Lower Granite Dam. |
a. Analyze all collected data and provide quarterly and annual reports. Present information annually at professional meetings. |
|
$24,000 |
|
3. Determine relationships between environmental factors where wild parr reside and subsequent movements of parr/smolts through downstream traps and dams. |
a. Perform maintenance on environmental monitors and upload environmental data every four months. |
|
$41,400 |
|
3. |
b. Acquire data on wild juvenile chinook salmon movements out of natal rearing areas through stream traps that are located next to environmental monitors. |
|
$19,400 |
|
4. Determine the influence of seasonal climatic conditions and environmental factors within streams on wild chinook salmon parr/smolt movements out of natal rearing areas and to Lower Granite Dam. |
a. Analyze all collected data and provide quarterly reports. Present information annually at professional meetings. |
|
$24,000 |

This information was not provided on the original proposals, but was generated during the review process.
This project is not coordinated well with managers. Data could be collected in conjunction with other studies. Concerns with tagging populations on the verge of extinction. Data gathered may not be worth the risk to the populations. Information provided by the project has only been marginally useful. This project is viewed by NMFS as a requirement under the Biological Opinion.
