CPCB faciltated and created databases for the Nutrient Criteria Workgroup, also called the "US EPA Region 7 Regional Technical Assistance Group", which works together to establish nutrient criteria for lakes, streams, and wetlands of the US EPA Region 7 and the Central Plains Region.

The Region 7 Lake Nutrient Criteria document is completed and available below. During the lake meetings, the RTAG developed a list of reference lakes located in USEPA Region 7.
