Cooperators: City of Harmony Fire Department, Earth Systems Class ‐ Fillmore Central High School, Kwik Trip of Harmony.A dye trace was conducted in an area in the City of Harmony, Minnesota from May 6, 2008 to June 13, 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 Buggywhip, Hart, and the Big Spring 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.enDye TracingDye TraceKarstSpringsSinkholeFluorescentDyeSpringshedSinking StreamPseudokarstReport
