Amphibian survey in Cavanaugh Pond

King County ecologists were up to their hip waders in Cavanaugh Pond recently as they surveyed amphibian eggs to document what species are present as part of the Riverbend Levee Setback and Floodplain Restoration Project.

Cavanaugh Pond and the area that was the former Riverbend Mobile Home Park will be reconnected to the Cedar River to restore approximately 40 acres of floodplain, which will reduce flood risks and improve the quality and quantity of salmon habitat.

Efforts to document current species prior to construction allows the project team to plan for protection and relocation efforts, if needed. Construction to restore floodplain is anticipated to begin next summer.
