The Pollutant Load Reduction Model is part of a multi-stakeholder effort to provide technical tools for project planners, funders, implementers, and regulators to work collaboratively to minimize the deleterious effects of urban storm water on the remarkable clarity of Lake Tahoe, a keystone in the ecological and economic health of the Lake Tahoe Basin.  This product would not be possible without the generous participation of several Basin regulatory and project implementing entities. This specific product is authorized pursuant to Section 234 of the Water Resources Development Act of 1996 (PL 104-303) which provides for coordinated interagency efforts in the pursuit of water quality and watershed planning.
