Morning Releases to Be Decreased for an Eight Hour Period November 2nd through 
  6th  
From 
  3am to noon (Mountain Standard Time) from November 2nd through 6th, releases 
  from Davis Dam will be decreased to approximately 4,800 cubic feet per second. 
  This decrease will allow Reclamation crews to dredge Laughlin Lagoon, located 
  in the river channel just south of the city of Laughlin, Nevada.
The 
  decrease in flow is expected to temporarily lower the level of the river below 
  Davis Dam as much as eight feet. Afternoon on each day, the releases will be 
  returned to approximately 15,000 cfs, and the river is expected to return to 
  its normal elevation of approximately 504 feet above sea level.
Water 
  craft users could be affected by these lake levels and should excerise extreme 
  caution when navigating the Colorado River below Davis Dam during this low water 
  period.
This 
  change to operations is not expected to affect the elevation of Lake Mohave 
  which is presently at 629.3.
Laughlin 
  Lagoon was created in 1958 by a Bureau of Reclamation river realignment, and 
  over the years, the area has degraded. Reclamation, in participation with several 
  local partners, is working to regain and maintain the quality of this backwater. 
  Under a $1.3 million program, Reclamation has installed culverts to improve 
  the quality of water flowing into the lagoon, and will dredge the area to provide 
  enchanced access for water recreationists.
