Wide Hollow Creek historically supported a robust run of spawning coho salmon, as well as steelhead. It is likely that high numbers of spring chinook juveniles also reared in lower Wide Hollow Creek. Today, this channel is in extremely poor condition due to floodplain encroachment, routing of untreated storm water into the channel, irrigation, diking and channelization. Summer rearing in this channel is nil due to high temperatures. Sediment and other pollutants levels are also high. Wide Hollow Creek does not meet water quality standards for DDT, 4,4’-DDE, 4,4'-DDD, Dieldrin, Alpha-Endosulfan, Temperature, Dissolved Oxygen and Fecal Coliform. This project would address water quality and habitat problems through the following practices: 1. Install juvenile fish passage at the drop structure; 2. design and implement a storm water management plan for the drainage; 3. enhance rearing habitat by restoring riparian vegetation, relieving floodplain constrictions where possible, adding large woody debris and angular rock to the channel; and, 4. implement a public education and involvement program to involve landowners, school districts and interest groups in water quality monitoring, restoration and maintenance.

Specific measureable objectives
Fish density will be determined and water quality data will be collected pre- and post-project implementation throughout season of use. Changes in riparian canopy closure will also be measured.
Restoring riparian habitat, improving water quality and adding stream complexity will increase rearing productivity.
Underlying assumptions or critical constraints
The hydrograph will be similar to historic; water quality will remain adequate to support anadromous fish during season of use (i.e. discharge of toxic substances to the stream will not occur); a minimum of twenty percent of the landowners in the project area will participate
Fish density will be determined by mark and recapture methods. Three reaches will be sampled at three different times during the season of use (early fall through late spring). Equipment will include normal fish sampling tools.
Water quality will be monitored for the following parameters: D.O., temp., BOD, fecal coliform, phosphates and lead.
Changes in riparian canopy will be determined with a densiometer.
Brief schedule of activities
The project would be initiated with the mailing of fliers to landowners. Affected public agencies would also be contacted. Public meetings would be held to discuss stream functions, appropriate management and the goals of the project. Past habitat restoration/protection successes that the Yakama Indian Nation has undertaken would be displayed. Landowners would be solicited to voluntarily initiate riparian restoration/protection on their land. In-channel structures, such as large woody debris, would be placed at appropriate locations. Flood easements at critical locations would be purchased. Engineering studies would be completed to determine the best approach to address stormwater problems. A stormwater management plan would be written and the end of year one. In year two, further riparian restoration projects would be implemented. The action items identified in the stormwater plan would be implemented. Monitoring would occur in years three and four. Ultimately, field trips would be scheduled to display individual restoration projects.
Managers believe rearing habitat for juvenile fish is severely limited in the Yakima Basin. This project would redress rearing habitat function through increasing riparian canopy closure, improving stormwater treatment and increasing in-channel habitat complexity.
Rearing habitat for juvenile fish is severely limited in the Yakima Basin, so much so that fish managers believe rearing habitat restoration is one of most important actions to restore stock health.
Summary of expected outcome
Stormwater treatment will improve. Flood impacts would decrease. Native riparian vegetation density will increase. In turn, water quality will improve, in-channel habitat complexity will increase and stream banks will become more stable. Landowners will become more aware of anadromous fish needs and other reasons for effectively treating stormwater and preserving/restoring riparian vegetation. Ultimately, the project will be used as a local demonstration area to encourage additional landowners to protect and restore streams.
Dependencies/opportunities for cooperation
The stormwater plan would have oversite by affected public agencies. Individual restoration projects will be developed in consultation with the USDA - NRCS and the WDOE. Cost-share applications will be presented to the USDA - CFSA, the WDNR, the USFWS, and other agencies that administer funding programs. Hydraulics Permit Applications (HPA’s) will be required for all in-channel work requiring heavy equipment. These will be processed two months prior to anticipated work.
Invasive weedy species may out-compete native plantings. Flooding may remove large woody debris.
Monitoring of water quality revegetation success will be done for three years. Weed control and replanting will be done as necessary.
