Description of Pilot Project
The Kootenai River White Sturgeon Recovery Team (SRT) identified spawning substrate as the alternative with the best opportunity for measurable success in the Shorty's Reach, given the limited time and funds available. The lack of appropriate spawning substrate is thought to be a primary factor responsible for sturgeon recruitment failure. Sturgeon consistently spawn in deep high-velocity parts of the river channel near Shorty's Island but shifting dunes of fine sediment in that reach cover and smother eggs. The USACE has considered several alternatives for providing suitable egg attachment substrates including rock, armor units, and pilings. The Recovery Team has identified rock as the most appropriate substrate based on a review of preferred spawning sites in other sturgeon populations. Rocks can provide the necessary attachment surfaces and clear interstitial spaces needed for embryo (fertilized egg) incubation and early larval rearing. Before a large-scale substrate introduction project is implemented, more information is needed to determine whether rock placement will produce the desired conditions. Critical questions include whether rock can be placed so that at least some protrudes above the soft river bottom substrate and whether interstitial spaces will remain free of sand. Therefore, weather-permitting, a pilot project will be implemented in the late fall/early winter of 2005/2006. | $1,500 | 0.33% | 10/16/2005 | 10/15/2006 |
| C | 15511 | 157 | Collect/Generate/Validate Field and Lab Data | Velocity and Turbulence Eductors Field Test | Explore whether mechanical devices can effectively increase local water velocity and turbulence at a scale likely to prove useful in sturgeon habitat restoration by field testing flow eductors under different habitat conditions.
An additional intent of this pilot project is to explore whether eductors might be used to increase velocity and turbulence over a significant area in a natural river setting. This project is focused solely on physical effects. Future studies of biological effects will be considered based on physical effects measured in this pilot study. Bathymetry mapping at potential eductor sites has already been completed by the USGS. | $31,000 | 6.90% | 11/15/2005 | 10/14/2006 |
| D | 15512 | 162 | Analyze/Interpret Data | Velocity and Turbulence Eductors Analyses | Eductors are portable tubes with attached nozzles and pumps which entrain and propel a directional stream of water. Although no quantitative turbulence characterization has been performed for white sturgeon spawning habitat use, preferred spawning conditions used by other white sturgeon populations include high water velocity and apparent turbulence. Velocities in the current spawning reach are near the low end of those reported for other sturgeon populations. Peak velocities are around 1.2 feet per second (fps) and more typically less than 1 fps. Preferred mean water column velocities for spawning by sturgeon in other areas are typically between 1 and 3 fps (Anders 1991; Parsley et al. 1994; Paragamian et al. 2001; Anders 2002; Golder Associates 2005). Eductors may: 1) increase water velocity and turbulence in current spawning areas, 2) attract spawners to adjacent areas of more suitable habitat, 3) help exclude egg predators, and 4) clean fine material from natural and engineered spawning substrates. Eductors are not proposed as a sturgeon recovery measure, but as a tool to help understand hydraulics associated with spawning and possibly incubation habitat requirements. | $10,000 | 2.23% | 11/01/2005 | 10/14/2006 |

Improve the characterization of riverbed stability and bedform movement in the white sturgeon spawning reach. Develop capability to continuously monitor suspended-sediment input into the Kootenai River white sturgeon spawning reach. Describe availability and movement of fluvial sediment through white sturgeon spawning habitat and identify where habitat substrate is currently aggrading, degrading, and stable. Video the riverbed at select spawning sites. Images of the river bottom will provide biologists a glimpse of the white sturgeon spawning habitat and provide some additional information for the design phase for spawning habitat enhancements. | $28,069 | 6.25% | 10/16/2005 | 10/15/2006 |

| J | 15518 | 157 | Collect/Generate/Validate Field and Lab Data | Riparian Habitat Hypothesis Lab Test | The Riparian Habitat Hypothesis attributes the widespread collapse of resident white sturgeon populations primarily to the loss of flooded riparian vegetation which might provide critical incubation and feeding conditions (Coutant 2004). Over 90% of this historical floodplain habitat in the Kootenai Valley has been lost to a combination of levee construction, Kootenay Lake elevation control, and Libby Dam discharge regulation. This hypothesis proposes that submerged riparian habitat during seasonal high water is needed for egg attachment and early development. Floodplain habitat effects on sturgeon are likely very complex and it is unclear whether significant functions include egg attachment and early life history. Additional studies could shed some light on the role of flooded riparian habitat in the sturgeon life cycle and related habitat restoration measures that might prove beneficial | $40,000 | 8.91% | 10/16/2005 | 10/15/2006 |
