Dry-Redwater Regional Water Authorization Act

This bill authorizes the construction of the Dry-Redwater Regional Water Authority System to provide water for municipal, rural, and industrial use in five Montana counties and one North Dakota county. It allows the federal government to fund up to 75% of the project's planning, design, and construction costs, with the federal share covering facilities like water storage, treatment, and transmission pipelines. The legislation also enables the water system to receive electricity from the Pick-Sloan Program at a firm power rate, provided the system operates on a not-for-profit basis. Finally, the bill authorizes $602 million in federal funding for the project between fiscal years 2027 and 2037, with provisions to adjust the amount based on construction cost fluctuations.
