Why was the data set created?

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.

How was the data set created?

1. From what previous works were the data drawn?

2. How were the data generated, processed, and modified?

   Date: Unknown (process 1 of 1)

   See Open File Report 2006-1318, Chapter 2 - Methods, Boundary and Initial Conditions, Bed Sediment section, page 2-9, for sample processing description.

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

2. How accurate are the geographic locations?

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

3. How accurate are the heights or depths?

   Depth measurements were obtained using an echosounder. Depths are to 1.0 meters precision.

4. Where are the gaps in the data? What is missing?

   unspecified

5. How consistent are the relationships among the observations, including topology?

   unspecified

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
