Watershed Lodge is set among spring-fed ponds on a 2,000-acre ranch in southern Montana, within the floodplain near the mouth of the Yellowstone River. The landscape—defined by seasonal water, expansive skies, and distant mountain ranges—has long been stewarded as a place to be preserved and experienced rather than altered. A grove of cottonwoods provides the site’s primary shelter, framing views toward the Crazy Mountains beyond.

Seasonal flooding from mountain snowmelt is both a defining condition and a design driver. The lodge is raised on a 30-inch porous plinth, lifting finished floors above the flood line while allowing rising waters to pass freely beneath and around the structure. Spring-fed ponds within the floodplain accept seasonal overflow and provide year-round water features during drought cycles. These ponds also support a geothermal system that conditions the house throughout the year, along with irrigation and non-potable water use.

The 3,000-square-foot lodge is composed of two interlocking volumes: a two-story glass wedge and a one-story wood-clad bar, together forming a T-shaped plan. Salvaged barn wood and local stone ground the building in its agricultural context, while broad roof overhangs, high-performance glazing, and radiant heating moderate energy use across seasons. A covered western walkway recalls the scale and utility of shed-lined streets in frontier towns.

Inside, rich yet restrained materials allow the surrounding landscape to remain the focus. A suspended fireplace anchors the open plan, mediating between entry and living spaces. Modern in form yet deeply responsive to place, the lodge is shaped by water, climate, and the enduring logic of the land.
