The United States Army Corp of Engineers (USACE) intends to award before 30 September 2026, a noncompetitive firm fixed price contract to the Confederated Tribes of Warm Springs (CTWSRO) as part of its joint requirement for management of historic properties affected by operations of the Federal Columbia River Power System. Qualified staff, including a Tribal cultural representative, will visit Memaloose Island monthly to document ongoing effects from FCRPS operations and maintenance and gather information that can assist in meeting long-term cultural resource management objectives. These actions include: Observing, documenting, and reporting on the physical dynamics of the erosional or depositional processes at monitored sites. Recording site conditions to provide information from which future changes such as sediment loss, topographic change, vegetation change, human and animal use impacts, soil disturbance, and vandalism can be quantitatively determined. Monitoring for looting, vandalism, and burial desecration at designated sites and ensuring the notification of proper authorities. Accurate documentation of the variation and diversity of potential impacts and causal factors at the site. Providing tribal insight about the religious and cultural significance of sites. Providing recommendations for treatment of monitored sites including recommendations regarding future monitoring frequency. This project requires technical expertise and access to unique and confidential information held only by the CTWSRO, a federally recognized tribe as identified in 84 Federal Register 1200. There are no known alternatives for these services that possess knowledge of the CTWSRO tribal history or could speak on their behalf.
