Future of Cascade and Lake Tapps Reservoir (June 2021)

On June 30, 2021, the Board of Directors held a workshop on the Future of Cascade and Lake Tapps Reservoir. The workshop evaluated alternative scenarios for Cascade’s long-term water supply and development of the Lake Tapps Reservoir. It also focused on the implementation of a Water Supply Development Fund (WSDF) to provide a financial structure to accumulate cash for a future major water supply project and reduce and smooth out rate impacts.
