CBP partners include federal and state agencies, local governments, non- profit organizations and academic institutions. The CBP has a number of goal teams, advisory committees and workgroups to facilitate its partners’ coordinated efforts (Figure 1). The Water Quality Goal Implementation Team (WQGIT) works to evaluate, focus and accelerate the implementation of practices, policies and programs that will restore water quality in the Chesapeake Bay and its tributaries. Those involved in the WQGIT and its numerous workgroups are among the individuals most deeply involved with implementation, tracking and reporting of best
