The question of Capital Lake was addressed directly and indirectly last week.
An article about Lakefair stated that the festival had become separated from the lake, which is rapidly becoming an alluvial plain infested by the snails.
The siltation rate was stated to be about 47,000 cubic years per year. The indirect reference was at the Port Commissioners’ July 22 meeting, where plans for port dredging this fall said that 45,000 cubic yards would be removed. An interesting similarity in the amounts.
The problem is visible at low tide, exposing the mud bank on the western half of the area north of the Olympia Yacht Club. The mud bank was not nearly as large when I moved to Olympia in 1990.
Obviously, dredging must be done, above or below the Fourth Avenue Dam, to deal with the river’s continued deposits.
The best scheme would be to remove the dam and do cooperative scheduled dredging paid for by all affected agencies to maintain good river flow, kill the snails and keep the port and yacht basin open. The lake would then be usable at higher tides and use of the estuary by salmon would once again be unimpeded.
