CLIPA White Paper - Lake Maintenance Plan

Alternative Considerations for Dredging Spoils

Alternative considerations for the use of future lake maintenance dredging spoils and/or Budd Inlet dredging spoils are:
  • Transport spoils to Percival Cove to create wetland viewing areas, pathways and parklands by strategically placing dredging spoils within the cove area. (This option is preferred over placing the dredging spoils within the Middle basin area.)
  • Transfer spoils to Budd Inlet west bay shoreline for boardwalk and park development by the City of Olympia for its West Bay Waterfront Park plan.
  • Transfer spoils to create a shoreline boardwalk and park-strip area along the extreme west side of the Budd Inlet lagoon located just north of the new 4th Avenue bridge. Currently, the steep bank ends abruptly into the lagoon water’s edge without an upland “land-bridge” for cross access. A bulkhead and sediment backfill could be used to extend the future park-strip and boardwalk to benefit the City of Olympia’s interest.
  • Create a park and water’s edge “launching area” into the lagoon for access to Budd Inlet by canoes, kayaks, and similarly-sized boats. A drive access to this area could be created from the north end of Deschutes Parkway under the 4th Avenue and 5th Avenue bridges on the west side.
  • Transport spoils to Budd Inlet for loading onto barges and disposal at a deep-water disposal site.
  • Consider creating an “up-river” dredging pocket area for periodic easy access maintenance dredging to capture and remove sediment prior to entry into the lake system. These dredging spoils could be dewatered at the dredging site for later truck hauling to landfills, quarry reclamation, landscape use, etc.

    A possible location is within the Olympia brewery and City of Tumwater properties.
    The DeschutesRiver flows through south of the brewery and north of the Tumwater Valley golf course.
    Large brushy riverfront acreage exists at this location.

We recommend that the issues of Capitol Lake water quality such as fecal coliform, dissolved oxygen, temperature, pH, and turbidity may be better addressed with the up-river sediment management approach.
 
We also recommend that the current purple loosestrife eradication program be aggressively continued to its extinction within the Capitol Lake system.
