The first phase of the study included the dredging of a hole near the lake outlet. The intent was to use this hole for enhanced nutrient removal either by subsequent dredging or bottom withdrawal. The second phase of the project involved development of innovative dredging equipment to remove organic rich sediments. This aspect was accomplished but land management of dredged sediments became too complex. The final phase, the bottom withdrawal project was successfully completed by collaboration between NWRI, UBC Civil Engineering, local residents and BC governments. The eutrophication of the lake was greatly reduced and the local citizens continue to maintain the bottom withdrawal themselves"--Management perspective. |
