BACKGROUND <br />As part of mining operations conducted at the Tri County Gravel pit near Hotchkiss, CO, a dike <br />was constructed between the north fork of the Gunnison River and the mining operation. In 2005 <br />Tri County Gravel repaired the dike dividing the Tri County Gravel mining operation from the <br />north fork of the Gunnison River. This repair was necessary after a flood event in 2005 caused <br />the failure of the dike at both the upstream and downstream ends. The upstream dike repair was <br />conducted following the guidance of Crane & Associates in Delta, CO. The downstream dike <br />repair remains to be completed. <br />In December 2007, Huddleston-Berry Engineering & Testing drilled three holes across the area <br />of the upstream repair and gathered samples for testing. The data from these holes has been used <br />to create material cross-section of the dike for the purposes of this slope stability analysis. The <br />details of the Huddleston-Berry report can be found in Appendix A. <br />Tri County Dike Slope Stability Jan 08 2
