CLIPA White Paper - Lake Maintenance Plan

Lower Budd Inlet Marine Dredge

A dredging operation within the lower Budd Inlet and Percival Landing boat basin is also recommended during the first phase dredging scenario, beginning in the first year of the second biennium (2013-2015). The funding request reflects this activity.
 
This dredging task could be accomplished with various types of dredging equipment and barges, with dredging spoils to be relocated along the western shoreline of lower Budd Inlet for park/boardwalk development. The dredge spoils also could be sent off for deep water disposal (e.g., Anderson Island, or Commencement Bay).
(See Figure 4 – Budd Inlet Boat Basin Dredge - Image)
 
  • Dredging within the lower Budd Inlet, including the western section and the boat marinas, must be done to relieve shallow waters that ultimately interfere with navigation. This accumulated sedimentation was created by recent years of sediment drop-out of increased materials transferred from Capitol Lake through the dam during the twice per day drain-downs.
  • Dredging of the resultant “mud flats” from this accumulating sedimentation directly north of the dam and west of the Olympia Yacht Club must be dredged to re-open the “flow-channel” into the northern inlet.
    (See Figure 4 – Budd Inlet Boat Basin Dredge - Image)

    This mud flat area created by lack of State maintenance to Capitol Lake is resulting in a blockage of the natural northerly current flow of water being drained from Capitol Lake each day, and redirects the current and sediment easterly and directly into and through the Olympia Yacht Club moorings.

    The eddying effect also results in accumulating sediment being deposited into the water-dependent areas including Percival Landing, Martin Marina, One Tree Marina, Fiddlehead Marina, Percival Plaza, and the Port of Olympia. The unintended consequences result in impeding navigation and accumulating sediment deposition under a water-dependent use (the marina moorings).
