Water — clear, pure, bountiful — life blood of all things. And here in Montana we boast the headwaters of the nation. Within the purview of HHAA, the Missouri River arises from Prickly Pear and Little Prickly Pear Creeks, while the Columbia River emanates from the Little and Big Blackfoot Rivers. Rare waters providing home to native bull trout and west-slope cutthroat trout, but also arctic grayling, rainbow trout and brown trout. Our efforts focus on maintaining the health of these aquatic systems.
