On January 17, 
  2003, the Bureau of Reclamation will begin to decrease the elevation of Lake 
  Havasu to assist the Bureau of Land Management in their efforts to enhance recreation 
  sites around the lake.
Over the next 2 
  to 3 days, the lake will be lowered from its current elevation of 446.3 to elevation 
  445.5. The lake is expected to remain at this lower elevation through the end 
  of February. However, unforseen weather occurrences or other operational considerations 
  may result in short term fluctuations in elevation. The lake should return to 
  normal operating levels (approximately 445.8 feet msl) by early March.
All RIVER USERS 
  should remember that fluctuating river flows may conceal or create natural hazards 
  such as moving sandbars, gravel bars, unstable riverbanks, floating or submerged 
  debris, or other unfamiliar obstacles. Caution should be be exercised while 
  using the river between Davis Dam and the Mexican Border at San Luis, Arizona.
