The purpose of the study was to quantify existing Lake Fork channel conditions to establish a baseline against which post-rehabilitation conditions can be compared."

The majority of the surveying occurred between August 2-6, 2010, with additional flood-plain surveying on May 24, 2011 and April 11, 2012. Topographical surveying of water-surface elevations includes conditions present during each day of surveying as well as preserved high-flow conditions (high-water marks) from Spring 2010 and 2011 that were identified from sediment deposition and debris lines. Eight monumented cross sections were established in the study reach for long-term channel monitoring."

     "text": "The Lake Fork of the Gunnison River has been an area of active channel modification since the 1950s (Lake Fork Valley Conservancy, 2010).  In the 1950s, increased rates of land use change within Lake City have resulted in the straightening and channelization of the Lake Fork to promote channel stability and development of riverfront properties. Sediment-retention structure failures (cribbing piles) on Henson Creek in the 1960s and 1970s have contributed large volumes of sediment into the fluvial system. In the late 1980s and early 1990s, the Colorado Department of Transportation (CDOT) built temporary berm structures along the river on the north side of town to protect the highway from channel migration until permanent structures could be completed. Areas downstream of the 8 \u00bd street bridge were also straightened by CDOT and U.S. Army Corps of Engineers in the 1980s."
