Monroe Area Recharge Project
Solicitation # RFP-2026-0001
The Lower Loup Natural Resources District is seeking a qualified professional engineering consultant for the Monroe Area Recharge Project in southwestern Platte County, Nebraska. The project aims to design and implement a system to divert water from the Loup Power Canal into identified wetlands and drainages to facilitate groundwater recharge and baseflow retiming. The scope of work includes an existing conditions assessment, site identification and prioritization, conceptual and final design, permitting support, and the development of a final hydrologic modeling report and an operations and maintenance plan. All designs must adhere to Federal Energy Regulatory Commission requirements, including specific mandates for minimum flow in bypass reaches, run-of-canal operations, water temperature limits of 93 degrees Fahrenheit, and a maximum diversion of 2,000 cfs between March 1 and June 30. Proposals are due by 5:00 pm on October 2, 2026, and must consist of four hard copies and one digital version delivered to the district office in Ord, Nebraska. Selection will be based on technical qualifications, a proven track record with similar water retiming projects, the proposed approach, and cost effectiveness. Work is scheduled to commence by December 1, 2026, with a timeline to be mutually agreed upon following the award. The contract requires the consultant to be fully insured for general liability and workers compensation. Payment will be processed on a monthly basis, subject to a 10 percent retainage that will be released upon project completion.

Z--Mendota Pool Bypass and Reach 2B Improvements
Solicitation # 140R2026R0020
The Bureau of Reclamation, under the San Joaquin River Restoration Program and the San Joaquin River Restoration Settlement Act, is seeking industry input via Request for Information 140R2026R0020 for the Mendota Pool Bypass and Reach 2B Improvements. This large-scale civil works project in California is estimated to have a magnitude between 225 million and 300 million dollars. The primary objective is to construct channel and structural improvements to ensure a conveyance of at least 4,500 cfs from Reach 2B downstream to Reach 3. The project is divided into two phases: Phase 1 focuses on the Mendota Pool Bypass Channel to provide passage for Chinook salmon, including the construction of a control structure, fish ladder, and auxiliary water supply, with a goal of being operational by spring 2030. Phase 2 involves replacing intake locations in Reach 2B with a headworks structure, canal, and siphon or pipeline to maintain water delivery to the Columbia Mowry Delivery System. The government aims to begin construction on the channel and levee in 2027 and is currently evaluating the most effective delivery method, considering design-bid-build, design-build, or a hybrid approach. The project must comply with several environmental mandates, including the National Environmental Policy Act, the Clean Water Act, the Endangered Species Act, and the National Historic Preservation Act, and will require a Project Labor Agreement. As this is currently an RFI for market research and planning, the agency is soliciting feedback on risk allocation, constructability, and schedule estimates. Interested parties must execute a Federal Non-Disclosure Agreement to access detailed geotechnical reports, design drawings, and specifications. The primary point of contact for this effort is Stephanie Lindner.
