As the paradigm shift from command-and-control statutes to collaborative partnerships increases, public administrators, policy makers, and watershed stakeholders will become more dependent on collaborative partnerships to solve complex environmental problems. This article explores watershed management partnerships and suggests a new typology of collaboration built on the variable of governance. The typology categorizes three types of watershed partnerships as interagency governance, cross-sector governance, and grassroots governance. Understanding the strengths and weaknesses of watershed partnerships through the lens of governance structure will enhance public administrator and policy makers’ abilities to provide the best approach for addressing a particular watershed goal.
