This research investigates the ecological impact of beaver dam analogs (BDAs) on gravel bed river floodplains, focusing on Trail Creek in Gunnison County, Colorado. Historically, there were significant reductions in North American beaver populations, altering floodplain dynamics including, but not limited to, reduced hydrologic connectivity, depleted summer baseflow, and lessened capacity to store carbon and metals. Recently, the importance of beaver dams for riparian water and nutrient retention, as well as other ecosystem benefits, have been recognized. This study aims to understand how BDAs can enhance summer and late season baseflow volumes and hydrologic connectivity while also assessing their role in trapping colloidal carbon and metals. The project will leverage already installed and planned BDAs, as well as natural beaver dams, to establish before-and-after datasets. The findings are expected to contribute valuable insights into low-tech process-based restoration techniques and improve our understanding of complex ecosystem interactions and adaptations to climate-induced changes in glaciated mountain landscapes.
