Abstract:
This GIS layer contains bathymetric elevation bands (derived from bathymetric contours) of selected freshwater lakes in Washington State. The majority of the bathymetric contours were digitized from maps contained in a series of seven documents: Reconnissance Data on Lakes in Washington, Water-Supply Bulletin 43, Volume 1 through 7 by the United States Geological Survey in cooperation with the Washington State Department of Ecology. The exceptions are 1) Lake Chelan which was digitized in 2016 from the publiclication Morphometry of Lake Chelan (published in January 1987); 2) Lake Sammamish whose digital data was acquired from King County in 2013 and is derived from data collected during the publication of Development of a Three-Dimensional Hydrographic Model of Lake Sammamish (published in November 2008); and 3) Lake Crescent, whose digital bathymetric soundings were taken by a private party during 2013/2014 and provided to the Department of Ecology and were converted to contour lines in 2016.
Purpose:
Although both the importance and value of the Washington lakes are widely recognized, the quality and type of information currently available for most of the lakes are not adequate to provide the understanding needed for wise management of the lakes. Thus, the need to obtain additional information about lakes resulted in the initiation in 1970 of a cooperative program between the Washington Department of Ecology and the U.S., Geological Survey, whereby selected lakes in Washington would be investigated. In general, the study consists of a data-collection program designed to (1) document the present water quality and the overall status of the lakes, and (2) provide basic data pertaining to the physical, cultural, and water-quality characteristics of lakes in order to establish a base of reference that will allow periodic appraisals of future lake conditions. More than 750 lakes in all but four counties of the State were studied; these are equally distributed between western and eastern Washington. Most of the lakes investigated were 20 acres or larger in size and were selected because the constitute shorelines of the State covered under the Shoreline Management Act of 1971 (Washington State Department of Ecology, 1973). However, some of the lakes listed as constituiting shorelines of the State were not sampled; these included marshes with no open water or intermittent lakes which were dry at the time of visit.

Geospatial_Data_Presentation_Form: vector digital data
Other_Citation_Details:
These soundings are used to generate bathymetric lines, interpolated raster graphics, and 3D models of the lake bottom in an effort to determine the lake's depth and volume as well as to produce a comprehensive map of the entire lake bottom..The soundings were collected using an Apple iPad equipped with a GPS and a Garmin Echo 500c depth finder. Points were collected while performing a series of transects across and down the lake over several outings from August 2013 to April 2014. iPad GPS has an accuracy of approximately 2 meters. The Garmin Echo 500c depth finder had a vertical accuracy of 0.25-2.26%. These soundings are used to generate bathymetric lines, interpolated raster graphics, and 3D models of the lake bottom in an effort to determine the lake's depth and volume as well as to produce a comprehensive map of the entire lake bottom.
