This webpage is intended to provide up-to-date information regarding releases from Alamo Dam, focusing primarily on water quality. The US Army Corps of Engineers has released a hydrograph of the planned release from Alamo Dam, showing releases from March 12-31, 2018. CAP plans to monitor changes in water quality in Lake Havasu and the CAP system throughout the release period from Alamo Dam and to communicate the following to customers as events unfold:

  • Notifications from USACE regarding Alamo Dam Operations
  • Links to real-time information related to Alamo Dam data and pertinent USGS streamflow information
  • Updates regarding CAP operations
  • Pertinent Colorado River or CAP Water Quality data

CAP’s water quality sampling from Lake Havasu and the CAP canal will be made available as soon as possible. Additionally, normal real-time water quality data from Lake Havasu (at the CAP intake) and two points along the CAP canal are displayed in a chart.
