The Confederated Tribes of the Umatilla Indian Reservation (CTUIR), Department of Natural Resources Fisheries Program is currently requesting proposals for an in-stream design and construction oversight for restoration efforts within East Birch Creek. Proposals that present creativity, efficiency, and/or novel approaches are strongly encouraged. The implementation of this project will improve in-stream habitat for Endangered Species Act (ESA)- listed and non-ESA-listed fish species, while benefiting channel morphology and in-stream processes and protecting existing infrastructure. Additionally, this work will provide a basis on which to complete additional restoration efforts if they become necessary or feasible. The products from this effort will improve: base flow, shallow groundwater capacity, and capability of functional connection and interaction with the floodplain through hyporheic flow; channel form, sinuosity, complexity, geomorphic and hydrograph stability; the quality and diversity of in-stream and off-channel habitat for resident and anadromous fish; o stability and restoration of sediment routing processes; and, In-stream temperature, thus reducing channel dewatering, associated fish mortalities and improving passage.
These products are expected to reduce summer stream temperatures, improve overall channel stability and floodplain connectivity, water quality, and ultimately improve aquatic habitat conditions. Proposed actions are expected to specifically increase floodwater access to the e evolution of a more stable geomorphic streambed structure.
Please see DNR Fisheries Program page on the CTUIR website for complete RFP.
