Orphan Boy And Orphan Girl: Historical Information On Groundwater And Flooded Workings, Emelina Doucette
Orphan Boy And Orphan Girl: Historical Information On Groundwater And Flooded Workings, Emelina Doucette
Graduate Theses & Non-Theses
Groundwater has historically, and still is, a concern within the mining industry due to the relationships between potential environmental and safety impacts. Montana Technological University uses a once operating silver mine, the Orphan Boy, to provide students with hands-on experience and is known as the Underground Mine Education Center (UMEC). The UMEC, and neighboring Orphan Girl mine located at the World Museum of Mining, have experienced increasing water levels the past few years. A compilation of known information pertaining to the Orphan Girl and Orphan Boy groundwater connections is presented using historical groundwater and mine data, stope books, hydrographs, and …

Hydrologic Response Of Headwater Streams Restored With Beaver Dam Analogue Structures, Evan Norman
Graduate Theses & Non-Theses
In the semiarid and arid western United States, it is important to understand the potential effects of stream restoration on surface-water and groundwater. In this study, we evaluate the seasonal and annual hydrologic impacts of beaver-dam analogue (BDA) restoration in the Blacktail Creek (BTC) Watershed south of Butte, Montana. We monitored surface water flow, groundwater levels, temperature, and specific conductance primarily using a control-treatment study design. In treated reaches, groundwater levels were closer to the ground surface and showed less seasonal fluctuation. Changes in overall streamflow in the control reaches had stream losses and gains varying from -21.0 to 19.9 …
