Section 1. Administrative
| Proposal title | Lake Pend Oreille Invasive Fish |
| Proposal ID | 200706000 |
| Organization | Idaho Department of Fish & Game |
| Short description | Overall Project Goal: To insure that the recovery of native species (bull trout and westslope cutthroat trout) and sport-fish (kokanee) in Lake Pend Oreille is not jeopardized by the recent establishment of smallmouth bass and walleyes. |
| Information transfer | Results of the study will be written into 2 Master's theses, kept on file at the appropriate university library. Peer-reviewed publications may be submitted where appropriate, based on project findings. Annual reports will also be submitted to BPA as required by contract. A presentation on each projects results will be made at an American Fisheries Society Meeting. |

Section 5. Relationships to other projects
| Funding source | Related ID | Related title | Relationship |
|---|---|---|---|
| BPA | 199404700 | Lake Pend Oreille Fishery Recovery Project | The Lake Pend Oreille Fishery Recovery Project addresses the impacts of the federal hydropower system on kokanee and the effects to bull trout and rainbow trout in Lake Pend Oreille. The Lake Pend Oreille Invasive Fish project will directly benefit the recovery efforts being implemented and help determine if additional limiting factors (predation and competition from nonnative predators) are jeopardizing recovery efforts. These two projects will share office space and field equipment to help keep project cost down. |
| BPA | [no entry] | 200703800- Preserving/Enhancing Bull Trout and Westslope Cutthroat Trout within the Upper Pend Oreille Basin. | Both projects have similar goals of preserving native fish in the upper Pend Oreille area. One looks into the genetic aspects of preservation, the othe into the threats from exotic species. Both could use the same facility and could share manpower and equipment. |
Section 6. Biological objectives
| Biological objectives | Full description | Associated subbasin plan | Strategy |
|---|---|---|---|
| Minimize impacts of walleyes and smallmouth bass | By 2009 understand the negative impacts (i.e. location, timing, and extent) to bull trout, westslope cutthroat trout, and sport fish caused by smallmouth bass and walleyes, and make recommendations to minimize these impacts. | Intermountain | Province Level Objective 1C3 and strategy e and f under Subbasin Objective 1C1 of the Pend Oreille Subbasin Plan. |
Section 7. Work elements (coming back to this)
| Work element name | Work element title | Description | Start date | End date | Est budget |
|---|---|---|---|---|---|
| Produce Inventory or Assessment | Assess seasonal diets of smallmouth bass and walleyes in Lake Pend Oreille. | Smallmouth bass and walleyes will be collected during spring, summer, and fall using electrofishing and gillnetting. Particular emphasis will be placed on sampling between May and July near the mouths of Trestle Creek, Pack River, Granite Creek, Gold and North Gold Creeks because these are key tributary locations that contain emigrating bull trout, cutthroat trout, and kokanee (Trestle Creek and Granite Creek only). Additional sampling will also be done along the south shore of Scenic Bay between May and July when kokanee fry are emerging. Gut contents will be analyzed to identify prey items. Methods similar to those found in Vidergar (2000) will be used to evaluate changes or similarities in smallmouth bass diets identified in 1997 and 1998 from Lake Pend Oreille. Vidergar (2000) found that smallmouth bass (n=337) mostly consumed (73%) non-salmonid fish; however 18% of what they consumed was unidentified larval fish. | 3/1/2007 | 2/28/2009 | $137,900 |

| Produce Inventory or Assessment | Determine the relative abundance of smallmouth bass and walleyes in key areas of Lake Pend Oreille. | The relative abundance of smallmouth bass and walleyes will be determined by nighttime electrofishing and gillnetting. An effort will be made to pick up all sizes and species of fish. Electrofishing will be done with a 6 m Smith-Root SR-20EH electrofishing boat with boom-mounted anodes that is currently on the Lake Pend Oreille Fishery Recovery Project. Sampling will be conducted at key areas for native fish such as tributary mouths and the Clark Fork River delta. Sampling will also focus on areas important to kokanee such as spawning shoreline spawning sites. Gillnetting will also be used at important sites to capture fish too deep for the electrofishing gear. All fish will be measured to the nearest mm and selected game fish will also be weighed. We will retain representative samples of fish for aging using otoliths and scales (10 fish per10 mm size groups). The relative abundance of smallmouth bass and walleyes will be evaluated to determine key locations for future control efforts. | 3/1/2007 | 2/28/2009 | $140,000 |

| Produce Plan | Make recommendations on methods to minimize the impacts of smallmouth bass and walleyes on focal species. | If concentrations of smallmouth bass or walleyes are found at a specific location, and diet analysis shows the presence of focal species, then, recommendations will be made on how to focus control methods to the specific area. Catch rates and stomach contents will be recorded as a baseline for future comparison. For example, if a concentration of walleyes were documented at a certain stream mouth, one recommendation could be to use large-mesh gillnets during May to July to collect walleyes but avoid capturing small salmonids (< 150 mm). Recommendation will be made as to how, when, and where, control methods would be most effective. | 3/1/2008 | 2/28/2009 | $10,000 |

Section 9. Project future
|
FY 2010 estimated budget: $0 FY 2011 estimated budget: $0 |
Comments: Project ends in 2008 with no outyear money needed. |
Future O&M costs: Depending on project findings, Idaho Fish and Game will use the information from these projects in control efforts that may include regulation changes, netting, or other efforts to control these species. Findings may also serve as the basis for future proposals in 2009.
Termination date: FY 2009
Comments: Funding is requested for 2 years, so no funds would be needed in 2009.
Final deliverables: Theses, annual reports and presentations (if requested) will be given to BPA that include recommendations of methods to minimize impacts of smallmouth bass and walleyes on native and focal species.

ISRP PRELIMINARY REVIEW (Jun 2, 2006)
Recommendation: Not fundable
NPCC comments: The presence of walleye and smallmouth bass can hardly be anything but detrimental to co-occurring native salmonids. The fact that this conclusion is publicly voiced by IDFG in an article on the situation in the Coeur d'Alene newspaper (CDA Press, 12 April 2006), but not in the proposal, leads the ISRP to question the thoroughness of this proposal. It is clear that three years of study are not needed to assess the situation. Immediate management action to suppress walleye and bass is appropriate if not already too late.
ISRP FINAL REVIEW (Aug 31, 2006)
Recommendation: Not fundable
NPCC comments: The response is minimal. The proposal is inadequate and not justified. The ISRP maintains its preliminary recommendation of "Not fundable." ISRP comments (June 2006): The presence of walleye and smallmouth bass can hardly be anything but detrimental to co-occurring native salmonids. The fact that this conclusion is publicly voiced by IDFG in an article on the situation in the Coeur d'Alene newspaper (CDA Press, 12 April 2006), but not in the proposal, leads the ISRP to question the thoroughness of this proposal.
