Stream channel morphology drives the health of riparian and floodplain ecosystems while impacting groundwater connectivity especially in high divide regions. This talk will overview the significance of beaver dam analogue (BDA) installations in the upper stretches of Blacktail and Basin Creek watersheds south of Butte. Monitoring was designed to look at spatial and temporal relationships of groundwater storage, fluxes and surface water balances. The data collected provides an insight into groundwater-surface water interactions along control and treatment reaches and the implications to ecosystems of this low-impact restoration technique.
