The Northwest Power Planning Council approved the Hood River and Pelton ladder master plans in 1992. The program implemented in the Hood River subbasin was initially called the Hood River Production Program (HRPP) and was designed to improve natural production of summer and winter steelhead and re establish spring chinook salmon in the subbasin. ODFW began funding the wild winter steelhead component of the program in December, 1991 along with the collection of pre implementation data on life history and production information. BPA began funding the monitoring and evaluation component of HRPP in August of 1992 and began preparing the programs EIS in 1995; which is planned for completion by the spring of 1996. The HRPP includes the development of hatchery facilities in the subbasin. A road to the proposed Powerdale Dam hatchery collection facility is approximately 90% complete and acclimation sites are in the process of being developed for use in 1996. The Powerdale Dam collection facility is currently under construction and is planned for completion in the fall of 1996. Modifications to the programs rearing facilities in Pelton ladder were completed in the fall of 1995. The HRPP is a coordinated effort between ODFW and CTWS.
Biological results achieved
A monitoring and evaluation program was begun in December of 1991 to collect the life history and production information needed to evaluate the HRPP and develop guidelines which will provide the greatest degree of protection to the native stocks of fish. We are currently collecting information on natural production, smolt to adult survival, escapement, harvest, life history, and several morphological and meristic parameters needed to characterize wild and hatchery stocks of summer and winter steelhead and natural and hatchery stocks of spring chinook salmon. Data collected to date has more accurately defined 1) the spatial distribution of spawning and rearing populations of anadromous salmonids; 2) the current status of indigenous populations of summer and winter steelhead; 3) potential impacts the historical subbasin hatchery program may have had on indigenous populations of fish; and 4) the status of presently available anadromous salmonid habitat in the subbasin. Information has been used to refine our approach for releasing hatchery smolts into the subbasin. Current data showing critically low escapements and natural smolt production also indicate the need to implement this program in a timely manner.

We are currently in the process of collecting baseline information which will be used to evaluate the HRPP. Preliminary information gathered from the monitoring and evaluation studies has been used to modify and refine guidelines for implementing the HRPP and has shown the necessity for implementing the HRPP in a timely manner. Radio telemetry work has shown that the East and Middle forks of the Hood River are primarily utilized by winter steelhead and that the West Fork of the Hood River is primarily utilized by summer steelhead and spring chinook salmon. This information has been used to identify where hatchery smolts will be released in the subbasin. The low post release survival rate observed for hatchery summer and winter steelhead smolt releases has shown the need to develop acclimation facilities for improving survival subsequent to release. Critically low and declining escapements of summer and winter steelhead, and the low estimates of wild steelhead smolt production, indicate the need to quickly implement the HRPP. ODFW's implementation of the native winter steelhead hatchery brood stock collection program, at a reduced level, has provided the basis for developing hatchery guidelines that will be used for fully implementing the native winter steelhead program under the HRPP. Habitat data is currently being evaluated to identify opportunities for increasing natural production in selected areas of the drainage. Data collected on streamflows in the East Fork of the Hood River indicate the need to take a more proactive approach towards enforcing existing water rights with the goal of providing a greater degree of protection for indigenous populations of fish.
Specific measureable objectives
The monitoring and evaluation studies are designed to provide the information needed to effectively implement the HRPP. Four broad categories of information will be collected to evaluate whether or not the HRPP is achieving its stated goals and objectives. Our management plan proposes collecting pre and post treatment data on smolt to adult survival, natural production (smolts), spawner escapements, various morphometric and meristic characteristics, juvenile rearing distribution, and temporal and spatial distribution of adult holding and spawning. Estimates of the inbasin post release survival rate and the smolt to adult survival rate will be used to evaluate the supplementation program and to develop methodologies for optimizing survival of the production releases. Estimates of subbasin smolt production will be monitored to evaluate whether or not we are increasing natural production. Estimates of spawner escapement will be used to determine whether or not we can achieve juvenile rearing capacity. A comparison of life history information and morphological and meristic characteristics of wild and hatchery stocks will be used to determine if 1) the genetic makeup of hatchery broodstock significantly deviates from the indigenous population and 2) the genetic makeup of indigenous populations has been impacted as a result of the HRPP. Information on the distribution of rearing juveniles and the temporal and spatial distribution of adult holding and spawning will be used to minimize the interaction between wild and hatchery fish.

Underlying assumptions or critical constraints
The proposed approach for implementing the HRPP is dependent on our ability to achieve objectives which were developed based on various assumptions about selected population parameters and environmental and physical constraints unique to the subbasin. Limited empirical information on various factors that could effect program success make it difficult to accurately assess our ability to achieve program goals in the timeframe defined in the HRPP's Environmental Impact Statement (EIS). The following are the programs primary critical constraints:
1) Summer and winter steelhead escapements are currently at critically low levels, and are declining, which would delay our ability to fully implement the HRPP.
2) Inclimate weather during the spring may restrict access to acclimation sites; restricting our ability to acclimate and volitionally release hatchery production groups.
3) Extremely high streamflows have been recorded during the fall in the Hood River subbasin. High streamflows are known to impact the egg to fry survival rate for spring chinook salmon. Depending upon the annual occurrence, and severity of, fall freshets it may be difficult to fully achieve program goals for the spring chinook salmon component of the HRPP.
The HRPP will primarily be evaluated using the following techniques:
1) Scoop traps will be operated at sites located in each major fork of the Hood River and in the mainstem Hood River to estimate numbers of wild anadromous salmonid smolt and fingerling production leaving each fork and leaving the Hood River subbasin and to estimate the numbers of hatchery smolts leaving the subbasin (ie. in basin post release survival). Numbers of smolts and fingerlings passing each scoop trap will be estimated using the Peterson mark and recapture methodology. Pre and post implementation estimates of wild smolt production will be compared to determine if natural production has increased.
2) An adult collection facility will be operated at Powerdale Dam to monitor spawner escapement. All fish must pass through the collection facility to pass above Powerdale Dam and the sport fishery primarily occurs below Powerdale Dam. Spawner escapement will be monitored to determine if the HRPP's spawner escapement goal is achieved.
3) A creel will be conducted below Powerdale Dam in order to estimate harvest and escapement to the Hood River subbasin (ie. spawner escapement plus harvest). Standard pressure counts will be conducted two weekdays and one weekend day each week. Daily harvest will be estimated using the area under the curve methodology. Harvest and subbasin escapement will be monitored to determine if the HRPP's goals are being met for each of these parameters.
4) Selected life history patterns and morphometric and meristic characteristics will be monitored for wild and hatchery summer and winter steelhead to evaluate the HRPP's impact on the wild populations and to evaluate how closely the hatchery population resembles the wild population based on the selected parameters. Wild and hatchery components of the adult steelhead run will be sampled at Powerdale Dam to estimate mean fork length and weight, freshwater and ocean age patterns, sex ratio, and run timing. Estimates for wild and hatchery adults will be compared to determine if the two components of the run are dissimilar. Estimates will be monitored through time to determine if the selected parameters have change for the wild run as a result of hatchery supplementation.
5) Wild and hatchery smolt steelhead will be coded wire tagged (CWT'd) to monitor smolt to adult survival rates, adult straying, harvest in the mainstem Columbia River, and hatchery rearing strategies. Wild steelhead smolts will be CWT'd at scoop traps located at selected sites in the Hood River subbasin and hatchery smolts will be CWT'd at Oak Springs Hatchery (ie. summer and winter steelhead) and Round Butte Hatchery (ie. spring chinook salmon). Tags will be recovered in Columbia River Basin fisheries and from a creel conducted in the Hood River subbasin.
Brief schedule of activities
Tasks planned for 1997 include monitoring 1) smolt production, 2) harvest, 3) jack and adult escapement to Powerdale Dam, and 4) juvenile rearing densities at selected index sites in the subbasin. Radio telemetry work conducted to determine spatial distribution of adult holding and spawning will be completed in FY 95. Further radio telemetry work may be implemented in 4 6 years. Two additional tasks being considered for future implementation include 1) developing gauging stations for monitoring streamflow at selected sites in the subbasin and 2) estimating smolt production from Neal Creek which is a major tributary to the mainstem Hood River. The gauging stations would be developed to monitor streamflow in relation to the minimum instream flows established at selected locations in the subbasin. We are proposing to develop a sampling site in Neal Creek because the sampling site established in the mainstem Hood River does not capture smolts migrating from Neal Creek.
The primary goal of the HRPP is to restore wild runs of summer and winter steelhead and to re introduce spring chinook salmon in the Hood River subbasin. The historical hatchery supplementation program utilized Skamania stock summer steelhead, Big Creek stock winter steelhead, and Carson stock spring chinook salmon. The HRPP would utilize wild stocks of summer and winter steelhead to develop hatchery broodstock with the primary goal of developing a hatchery fish that is more genetically similar to the indigenous populations. Deschutes stock hatchery spring chinook salmon would be used by the HRPP because it is felt that this stock is the most suitable stock available for developing the hatchery spring chinook salmon program in the Hood River subbasin. We are also proposing to collect hatchery broodstock from throughout the run, not gradeout juvenile fish in the hatchery production groups, and rear spring chinook salmon in Pelton ladder. This combination of actions is designed to produce a high quality hatchery smolt that is genetically similar to the wild population. Because of current funding constraints, it is doubtful that this more biologically sound approach could be implemented by ODFW without funding from BPA.
Critical uncertainties associated with the HRPP primarily center around our ability to implement a program that will have minimal impact on the wild population. Areas of primary concern include the following:
1) Hatchery broodstock is collected from throughout the entire run and juvenile hatchery production is not graded out prior to release. This combination of actions increases the potential that juveniles will not be at a typical smolt size at time of release and that the percentage of hatchery juveniles that residualize will be higher as a consequence. The extent to which residualism occurs will increase the potential for interaction between wild and hatchery juveniles and will reduce the post release survival rate.
2) Modifications are being made to the Powerdale Dam fish ladder as part of the overall development of the hatchery collection facilities. It is assumed that the modified ladder will not delay or impede passage of jack and adult salmonids above the dam. Further changes to the ladder may be necessary if passage is a problem.
3) The historical hatchery summer and winter steelhead program was implemented using out of basin stocks. The early run Big Creek stock of winter steelhead used as hatchery broodstock is not thought to have had a genetic impact on the native population because the Big Creek stock appears to spawn much earlier than the native population. The similarity in run timing between the wild Hood River stock of summer steelhead and the early run timing of the Skamania stock of hatchery summer steelhead used in the historical hatchery program indicates that some introgression of Skamania stock genes may have occurred in the wild population. This is based on the belief that wild Hood River stock summer steelhead, historically, had a much later run timing. The degree to which there was interaction between the wild and Skamania stocks of summer steelhead will influence the timeframe required to develop a hatchery stock similar to the native Hood River stock.
Summary of expected outcome
The HRPP's primarily goals and objectives include the following:
1) Improve wild summer and winter steelhead escapements and re introduce spring chinook salmon,
2) ensure that hatchery broodstock is genetically similar to the wild runs by developing hatchery broodstock from wild Hood River stock fish escaping to Powerdale Dam,
3) complete construction of hatchery collection facilities at Powerdale Dam and the isolation, incubation, and rearing facilities at Oak Springs Hatchery; adult holding and spawning facilities at Parkdale; and rearing facilities at Pelton ladder,
4) develop temporary acclimation facilities in each major fork of the Hood River subbasin,
5) develop biologically based guidelines for implementing the HRPP based on data collected from the monitoring and evaluation studies,
6) identify and implement habitat improvement projects that will enhance project benefits, and
7) increase harvest opportunities in both tribal and non tribal fisheries.
Dependencies/opportunities for cooperation
The HRPP is composed of five separate contracts that could impact the program if one or more contracts are not fully funded according to schedule. The five contracts primarily provide funding for three broad categories of activities. These include engineering, implementation, and monitoring and evaluation studies. Funding for the engineering component of the HRPP provides for the design and construction of facilities at Powerdale Dam, Parkdale, and Oak Springs Hatchery that are required to fully implement the HRPP. Funding for implementation provides for broodstock collection, holding and spawning, rearing, and marking and tagging. Funding for monitoring and evaluation studies provides for the evaluation of the HRPP and any interaction the hatchery program may be having on wild populations of fish. Inadequate, or loss of, funding for any component will jeopardize our ability to achieve project goals according to the timeframe established in the EIS. This is particularly crucial for construction work proposed for FY 97. The proposed adult holding and acclimation facilities at Parkdale are required to begin implementing the summer steelhead and spring chinook programs. Completion of hatchery facilities at Oak Springs Hatchery also needs to coincide with completion of the Parkdale facilities before we can begin implementing the summer steelhead program. The winter steelhead program could be implemented without the Parkdale facilities but at a much lower level than proposed for full implementation of the HRPP. The HRPP also relies heavily on the close cooperation of the USFS, PacifiCorp, CTWS, ODFW, Hood River Watershed Council, Farmers Irrigation District, East Fork Irrigation District, Middle Fork Irrigation District, and Longview Fibre. These various entities have supported project goals by way of 1) facilitating or allowing access to public and private lands, 2) providing consent to develop facilities on private lands, and 3) assisting in the implementation of project related tasks. Continued cooperation among these entities is crucial to achieving project goals.
There should be few risks associated with implementing the HRPP given the proposed scenario for implementing the program. Social and political risks should be minimal based on the strong support we have received to date from PacifiCorp, the various irrigation cooperatives, and local area sportfishers. The utilities, irrigation cooperatives, and Longview Fibre have also provided access to their property either for purposes of monitoring and evaluation or the development of facilities needed to implement the HRPP. Cooperation in this area has been crucial to implementing the HRPP because of the limited access available in the Hood River subbasin. There may be some biological risks associated with the HRPP but hatchery guidelines are being developed to minimize those risks. Guidelines will be based on information collected from an ongoing monitoring and evaluation program. Our primary goal is to minimize the impact on wild populations of summer and winter steelhead. There are no biological risks associated with spring chinook salmon program because the native population has been extirpated. Guidelines established for implementing the HRPP are designed to minimize biological risks associated with the summer and winter steelhead programs by 1) developing the hatchery broodstock from adults collected from throughout the wild run to the Hood River subbasin, 2) not grading out smaller juveniles in the production groups, 3) limiting production releases of each race to those forks where the population is principally located, and 4) releasing production groups at the lower end of the distribution of the population. The combined effect of these, and other, actions should minimize the impact the supplementation program has on the wild populations of steelhead.
We propose evaluating the HRPP primarily by implementing tasks designed to collect information on smolt production, subbasin and spawner escapements, and survival. Scoop traps will be operated at various locations in the subbasin to monitor subbasin wild smolt production and for estimating inbasin post release survival of hatchery production releases. Wild smolt production will be monitored to evaluate if the HRPP is achieving it's goal of increasing natural production. In basin post release survival of hatchery smolts will be monitored to evaluate the acclimation facilities. Spawner escapements will be monitored based on escapements to the adult collection facility at Powerdale Dam. Subbasin escapement will be monitored based on estimates of harvest below Powerdale Dam plus escapement to Powerdale Dam. A creel survey will be conducted below Powerdale Dam to estimate harvest. Wild and hatchery steelhead smolts will be coded wire tagged to estimate smolt to adult survival rates and to evaluate the straying rate for hatchery adults.
