Thesis (M.S., Water Resources) -- University of Idaho, 2016 | The 1972 Clean Water Act is the primary law for water quality protection in the United States. The Clean Water Act has been recognized as successful in limiting point source pollutants, yet the nonprofit protections are often criticized as ineffective. Nationally 42,457 waters are currently listed as impaired, mostly due to nonpoint pollution. Much of the criticism of nonpoint pollution protection focuses on the lack of mandatory regulation without study of current implementation to determine if management adjustments might also provide a solution. This thesis examines the implementation of the nonpoint source provisions of the CWA in Paradise Creek located in the Inland-Northwest of Idaho and Washington, illustrating that understanding of legacy effects, establishing a longer planning horizon, and resources to implement more extensive monitoring and adjustment of implementation accordingly, will lead to significant improvements in implementation.
