| Abstract/Description or Keywords | The Pemberton Valley Dyking District (PVDD) has been addressing flood protection issues and maintaining flood protection works in the Pemberton Valley since its inception on January 31, 1947. In 2002, Kerr Wood Leidal Associates Ltd. (KWL) produced the “Engineering Study for Lillooet River Corridor” (KWL, 2002), which included: a review of previous engineering studies and works from 1946 to 2002; an analysis of fluvial geomorphology for the Lillooet River corridor; an analysis of historical climate and hydrology for the Pemberton Valley and estimates of peak flows and lake levels at various return periods; development of a one-dimensional hydraulic model (Mike11) for the Lillooet River and flood profile estimates for the valley; an assessment of the existing flood protection network; recommendations for upgrades to flood protection; initial recommendations for gravel management in the Lillooet River; and recommendations for implementation of further flood protection works. Technical Memorandum – Lillooet Lake Lowering Analysis December 3, 2010 2 One question that has been raised periodically throughout the operation of PVDD is whether lowering of water levels in Lillooet Lake would have a significant, positive impact to the flood profile in Pemberton. The purpose of this analysis is to address this question through a brief hydraulic modelling exercise and through a review of existing information. |
