The Chesapeake Monitoring Cooperative was formed for the Integration of Citizen-based and Nontraditional Monitoring into the Chesapeake Bay Program Partnership. Do you monitor water quality or benthic macroinvertebrates within the Chesapeake Bay Watershed? Join the Coop! The CMC aims to unite monitoring groups and individuals in the watershed, provide technical support, and build a user friendly database that will facilitate the use of monitoring data by federal, state, and local government.
