Stream Restoration and the Importance of Understanding Groundwater and Surface Water Interactions

Document Type


Publication Date



Recent advances in stream restoration show that there is a growing need to more accurately monitor groundwater to determine changes in water fluxes, characterize groundwater and surface water interactions, and estimate changes in groundwater recharge and storage. This presentation will highlight two field sites. The first site is on the Middle Fork of the John Day River north of Galena, OR where there is stream re-routing and reclamation of mine tailings. Groundwater monitoring and modeling will be used to determine the effects of stream re-routing on nearby wetlands. The second site looks at the effects of water storage and flow from beaver mimicry structures placed along Blacktail and Basin Creeks in the Highland Mountains near Butte.
