    Ahrensfeld Creek and Borson Northeast Dye Trace Report 2007-2010 Winona County, MN
    (2017) Green, Jeffrey A; Alexander Jr., E. Calvin; Alexander, Scott C; Luhmann, Andrew J; Runkel, Anthony C; Peters, Andrew J
    Southeastern Minnesota’s karst lands support numerous trout streams. These trout streams are formed by springs discharging from Paleozoic bedrock. Dye tracing has been the tool of choice for mapping the springsheds (karst groundwater basins) that feed these springs. Previous work was focused on the Galena limestone karst. In order to accelerate springshed mapping, a two-year study was funded by the Minnesota Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources (LCCMR). Across southeastern Minnesota, numerous springs discharge from the Cambrian St. Lawrence formation. The St. Lawrence is considered to be a confining unit under the Minnesota well code. A dye trace was initiated when a stream sink was discovered in the upper St. Lawrence Formation. The sampling points included springs, stream crossings, and a municipal well that may be at risk for surface contamination. Dye was recovered at one spring in less than two weeks and at two other springs in less than three weeks. This translates into travel times of 200-300 meters/day. The springs all discharge from the lower St. Lawrence Formation. The St. Lawrence contains beds of dolostone; the dye trace demonstrates that there is a karst conduit flow component in this formation. This is evidence that these springs are significantly more susceptible to degradation than previously thought.

    Crystal Creek, Fillmore County Dye Tracing 2010
    (2010) Green, Jeffrey A; Kuehner, Kevin; Luhmann, Andrew J; Alexander Jr., E. Calvin
    Dye tracing was conducted at sinkholes in and around the Crystal Creek watershed in Bristol & Carimona Townships in Fillmore County. These traces were done as part of a cooperative effort between DNR, MDA and Fillmore County. The county and the MDA are working with landowners in the Crystal Creek watershed to study land management impacts on water resources. This area is underlain by Ordovician Galena limestone and is characterized by surface karst features. The predominant karst features are sinkholes and springs. The traces were done to begin to delineate the ground water basins (springsheds)that feed the springs that are the water sources for Crystal Creek. In karst areas like the Crystal Creek watershed, it is common for the ground water watershed to have different boundaries than the surface water watershed.

    Dye Trace Report Gorman Creek Trace: March 2011 Wabasha County, Minnesota
    (2017-02) Green, Jeffrey A; Luhmann, Andrew; Alexander, Scott C; Wheeler, Betty J; Alexander Jr., E. Calvin
    The karst lands of southeast Minnesota contain more than one hundred trout streams that receive perennial discharge from Paleozoic bedrock springs. Several of the Paleozoic bedrock aquifers that provide discharge to these streams are dominated by conduit-flow. Field investigations into the flow characteristics of these aquifers have been conducted using fluorescent dyes to map groundwater springsheds and characterize groundwater flow velocities for use in water resource protection. Gorman Creek is one of these designated trout streams. The creek is located roughly 14 kilometers (8.5 mi.) northeast of Plainview, Minnesota in Wabasha County (Figure 1). This trace was completed to add to delineated springsheds of the region as part of the Environmental and Natural Resources Trust Fund (ENRTF) Springshed Mapping project.

    Dye Trace Report Harmony, Minnesota Area Traces: October 2007, June 2009, and November 2010 Fillmore County, Minnesota
    (2016-06) Green, Jeffrey A; Peters, Andrew J; Luhmann, Andrew J; Alexander, Scott C; Wheeler, Betty J; Alexander Jr., E. Calvin
    Dye traces were conducted in the area of Harmony, MN in southern Fillmore County as part of the Environmental and Natural Resources Trust Fund (ENRTF) Springshed Mapping project. The traces described in this report were conducted to improve the delineation of the springsheds in the Harmony area. This report covers traces completed in October 2007, June 2009, and November 2010. Tracing had been completed in the vicinity previously for the ENRTF-Springshed project in the spring of 2008 (Green et al., 2008) and fall of 2008 (Green et al., 2009); as part of the ENRTF-Hydraulic Impacts of Quarries and Pits project from 2002-2004 (Green et al, 2003); in 1997 (Alexander et al, 1997); during the Fillmore County Geologic Atlas Project in 1993 and 1994 (Alexander et al, 1995); and for earlier work summarized in Alexander and others (1995) and by Kingston (1943).

    Dye Trace Report on Campbell Valley Creek Houston and Winona Counties, Minnesota 2012-2013
    (2016-12-13) Barry, John D; Green, Jeffrey A; Ustipak, Kelsi R; Wheeler, Betty J; Alexander Jr., E. Calvin
    The karst lands of southeast Minnesota contain more than one hundred trout streams that receive perennial discharge from Paleozoic bedrock springs. Several of the Paleozoic bedrock units that provide discharge are karst aquifers. Field investigations into the flow characteristics of these formations have been conducted using fluorescent dyes to map groundwater springsheds and characterize groundwater flow velocities for use in water resource protection. Campbell Valley Creek is one of these designated trout streams. The creek is located roughly 64 kilometers (40 mi.) southeast of Rochester, Minnesota in southern Winona and northern Houston counties (Figure 1). Two dye traces were conducted to add to delineated springsheds of the region as part of the Environmental and Natural Resources Trust Fund (ENRTF) Springshed Mapping project.

    Dye Tracing Within the St. Lawrence Confining Unit in Southeastern Minnesota

    Forestville North Dye Trace: September 5, 2008 to November 12, 2008
    (2008) Green, Jeffrey A; Peters, Andrew J; Luhmann, Andrew J; Alexander Jr., E. Calvin; Alexander, Scott C
    A dye trace was conducted in an area near Forestville State Park in Minnesota from September 5, 2008 to November 12, 2008 (Figure 1). Numerous dye traces have been completed in this area in the past and this effort was made in order to better delineate the springsheds in this area due to the close proximity of numerous State of Minnesota designated trout streams. Achieving a better understanding of the connection of these sinkholes receiving surface water flow and their connectivity to springs that provide a cold water source for the designated trout streams in the area was the goal of this trace. However, the goal of this trace was two‐fold, one sinkhole that received dye, Minnesota Karst Feature Database number 23:D2474, had previously been studied and was shown to be connected to cold water sources for two trout streams. The previous dye trace was completed during wet, spring conditions and this trace was completed during a much drier time in the late fall. Completing the trace during these differing conditions may help to better understand the seasonal changes of the subsurface flow of groundwater.

    Frego Creek Dye Trace: March 11, 2008 to June 16, 2008
    (2008) Green, Jeffrey A; Peters, Andrew J; Luhmann, Andrew J; Alexander Jr., E. Calvin; Alexander, Scott C
    A dye trace was conducted in an area near the city of Canton, Minnesota from March 11, 2008 to June 16, 2008. Dye traces have been completed in this area in the past and this effort was made to further refine delineation the springsheds in this area due to the close proximity of Frego Creek, a Minnesota designated trout stream. Much of the city of Canton’s stormwater flows to sinkholes throughout the city limits and some just outside of city limits. Achieving a better understanding of the connection of these sinkholes receiving this stormwater flow and their connectivity to springs that provide a cold water source for Frego Creek was the goal of this trace.
