Other Construction activities at John Martin Reservoir related to the <br />flood events: <br /> <br />Railroad Embankment: During a field inspection of the reservoir on May 6, John <br />Martin Project Office personnel discovered a slide on the Burlington Northern _ <br />Santa Fe railway embankment within the reservoir area. Railroad officials were <br />notified of this problem and on a subsequent inspection on May 11, it was noted <br />that the problem was getting worse. In response to this situation, railroad <br />officials placed a speed limit on all train traffic and took action to make the <br />necessary repairs. The railroad placed approximately 69 train cars of riprap at <br />this site to stabilize the slide and protect the embankment. <br /> <br />Fort Lyons Levee: On May 12th, sand boils were reported along a 1,200-foot <br />long section of the Fort Lyon VA Hospital levee. It was determined that the <br />situation posed no threat, but as a prudent precaution a contract was issued to <br />build a stabilizing berm on the hospital side of the levee. The berm was <br />constructed along the existing road embankment that had been placed by the <br />VA. The amount of fill required varied from 4 to 10 feet thick. This repair work <br />consisted of placing material to establish a working base, and placement of filter <br />material; then building an earthfilJ embankment 10 to 15 feet wide and 1,500 feet <br />long. A subsequent modification was issued to install manholes for the sub- <br />drains and additional material for a new wing dike south of the National <br />Cemetery . <br /> <br />South Wing Dam: Seepage was also noted along the toe of the south wing dam <br />on May 12th. It was determined that the seepage was passing through the rock <br />foundation under the embankment and that there was no threat to the integrity of <br />the dam. To manage the seepage, the Corps contracted to construct a seepage <br />control berm at the toe of this wing dam. This berm also serves to provide <br />access in this area for monitoring purposes. <br /> <br />4. Damages Prevented from Flood Control Operations. The Corps estimates <br />that there was $63 million in damages prevented due to flood control operations <br />in the basin. <br /> <br />5. Hydrographic Surveys. Hydrographic surveys of the sediment ranges at <br />Trinidad Lake and John Martin Reservoir were completed in June, 1999. New <br />elevation area-capacity tables for both projects were implemented on November <br />1,1999. <br /> <br />2 <br />
