Abstract

An ongoing debate centered around mining operations and tailings dam usage near the Minnesota mining range led to an investigation of potential environmental hazards near the cities of Hoyt Lakes and Embarrass. Topographic data from Satellite observations made available by USGS and HEC-RAS developed by US Engineer Corp are used to simulate the extent of mud flow from a hypothetical tailings dam break at the proposed mining site. Simulation results indicate significant flooding and pollution in the city of Embarrass, the lakes near The Legend at Giants Ridge, and the Embarrass River flowing southwest. Parts of the mud flow can also reach the...  more
