摘要

On Wednesday morning, October 11, 2000, a breach in the 72-acre Big Branch slurry impoundment caused the release of approximately 250 million gallons of coal slurry, a substance consisting of coal fines, other particles and water, into the Coldwater Fork and Wolf Creek Watersheds, through two mine portals ultimately affecting more than 100 miles of stream. Arguably, the most severly impacted section of stream was Coldwater Fork downstream of the portal. During the cleanups, approximately one mile of Coldwater Fork was relocated, resulting in an incised trapezoidal channel over much of the stream. While portions of the stream, particularly sections with good floodplain access, have recovered, other reaches are characterized by headcuts and a lack of riffle-pool sequences. Working for the Martin County Coal Corporation (MCCC), Fuller, Mossbarger, Scott and May, Inc. (FMSM) performed an assessment of the Upper Middle Fork of Coldwater Fork, and prepared a design and directed construction for nearly 6,000 feet of stream restoration.
