These data are the basis for the paragraph that begins, "In general, Capitol Lake is dominated by silt-sized sediment." See Open File Report 2006-1318, Chapter 2 - Methods, Boundary and Initial Conditions, Bed Sediment section, page 2-9, for the entire paragraph with its full description of Capitol Lake's bed.

Station site locations were obtained using Differential Global Positioning System (DGPS). Locations are in Washington State Plane South units to 1.0 meters precision.
Depth measurements were obtained using an echosounder. Depths are to 1.0 meters precision.
