The Omaha District has collected water quality data at Corps projects in the District since the late 1970's. The data have been assessed and summarized in water quality reports prepared by the District.  The data collected are stored in the U.S. Environmental Protection Agency's national STORET and WQX water quality database. The data can be accessed and downloaded online from the STORET/WQX website at www.epa.gov/storet. 

Recent water quality data collected by the District may not have been entered into STORET/WQX and can be obtained by contacing the District.

State environmental agencies responsible for surface water quality management routinely collect surface water quality data within their State. Water quality data have been collected by the States at Corps projects in the District. This information may be stored and accessible through the U.S. Environmental Protection Agency's STORET/WQX database. State water quality agency websites may publish water quality information on their web sites. The State of Nebraska, during the recreation season, publishes weekly bacteria and cyanobacteria toxin levels at District reservoirs with swimming beaches.

Local Watershed Management Authorities have been established to protect and improve water quality at the three Colorado Tributary Projects in the District:  Bear Creek, Chatfield, and Cherry Creek Reservoirs.  Each of these Watershed Authorities has adopted local water quality regulations and water quality management plans to protect and manage water quality at the respective reservoirs.  As part of these water quality management plans, the Watershed Authorities are implementing comprehensive water quality monitoring programs.  For efficiency purposes, the Corps ceased its water quality monitoring activities at the three Colorado Tributary Projects in 2002, and now defers to the respective Watershed Authorities for assessment of water quality conditions at Bear Creek, Chatfield, and Cherry Creek Reservoirs.  Persons interested in water quality conditions at the three Colorado tributary projects can visit the websites maintained by the following groups:

• Bear Creek Watershed Association (http://www.bearcreekwatershed.org/)
• Chatfield Watershed Authority(http://www.chatfieldwatershedauthority.org/)
• Cherry Creek Basin Watershed Authority (http://www.cherrycreekbasin.org/cc_home.asp)
