Collaborative watershed governance in lake tahoe: an institutional analysis

This paper examines the emergence of collaborative watershed management in Lake Tahoe by focusing on how institutions managing coordination and conflict have changed over time. It begins by describing the evolution of watershed governance and examines the extent to which the institutional arrangement demonstrates the eight design principles proposed by Elinor Ostrom for successful common pool resource (CPR) management. The paper then develops the concept of a complex environmental commons (CEC) to differentiate the situation of Lake Tahoe from the simpler CPR dilemmas frequently discussed in the CPR literature. We then propose five additional principles that contribute to collaborative management of a CEC.
