In its 11th year, Upper Missouri Waterkeeper secured a landmark litigation victory both halting the unlawful use of exempt wells and affirming the role of local government review for water resource impacts in subdivision development applications across the State of Montana. The organization also performed the largest-scale citizen-science water quality monitoring field season across the 9,000 square miles of the Jefferson sub-basin, focusing on collecting baseline data for temperature, dissolved oxygen, and nutrient parameters to better understand local water quality conditions amid a 40-year low in wild trout population numbers. The organization engaged over 100 volunteers in a variety of water restoration and advocacy projects, and reviewed and participated in over two-dozen government decisions concerning water resource management with a focus on improving protections for fishable, swimmable, drinkable water.

| IRS990/Desc | 0 | During this calendar year the organization secured a landmark litigation win in the Horse Creek Hills case, which concerned the lawfulness of the DNRC and County government in allowing sprawl development reliant on multiple exempt from review groundwater wells without any analysis of offsite impacts. The February 2024 case order put a stop to the DNRC's practice of allowing multiple exempt wells for new subdivision development, and also affirmed the critical and independent role of local government in assessing offsite water resource impacts, including affirming the legal value of local citizen input and public participation. Relatedly, the organization's Save Wild Trout campaign performed river monitoring across 36 locations on 5 rivers, developing a first-of-its-kind baseline of dissolved oxygen, temperature, and nutrient loading water quality data to inform river conservation efforts. This data can directly inform ongoing State efforts to understand the causes of unprecedented 40-year low recruitment in wild trout populations in SW Montana. The organization also successfully held the state water pollution control agency accountable to perform mandatory public participation in the design and authorization of new sewage infrastructure projects, including winning a preliminary injunction halting the spraying of sewage nearby a generational ranch owned by Waterkeeper members. |
