    19 June 2006 Dye Trace of the Cave Farm Blind Valley Stream Sink (MN23:B0058)
    (2006-08) Costello, Daniel E; Alexander Jr., E. Calvin
    A qualitative fluorescent dye trace has established that water sinking in the Cave Farm Blind Valley resurges at Bly’s Spring on Bear Creek in Fillmore County, Minnesota. This trace establishes the resurgence point for the Cave Farm Blind Valley and a lower limit of > 1 kilometer per day on the groundwater flow velocity. This trace documents the potential impact of a break in the British Petroleum pipeline, which is directly below the blind valley, could have on the Spring Valley karst. The Spring Valley karst also may act as an underground flow path that pirates water from Deer Creek to Bear Creek.

    Springshed Mapping in Support of Watershed Management
    (Proceedings of the 10th Multidisciplinary Conference on Sinkholes and the Engineering and Environmental Impacts of Karst. © 2005 American Society of Civil Engineers. Published online: April 26, 2012, 2005-09-28) Green, Jeffrey A; Alexander, Scott C; Alexander Jr., E. Calvin
    Fillmore County has been the focal point of dye tracing efforts in Minnesota for several decades. In 1995, a 1:100,000, county-scale springshed map was published. At the county scale, we primarily delineated springsheds greater than 500 hectares. After that project was completed, dye-tracing efforts continued and focused on the South Branch Root River (SBRR) springshed in the western part of the county. At the scale of the SBRR springshed (about 20% of the county), we expanded the boundaries of the large springsheds but also located and refined the boundaries of springsheds that are less than 200 hectares. We found one previously unmapped small springshed (Meyers springshed), documented complex flow boundaries between a large springshed (11. Canfield) and an adjacent small springshed (26. Rainy), and expanded the boundaries of four other springsheds. The small springsheds present a new opportunity for karst watershed research, monitoring and management. The small springsheds are often dominated by one or a few land uses, which permit simpler, more evident identification of the causes of water quality degradation.
