General Land Office Plats were downloaded from the BLM (http://landprx.pdxproxy.blm.gov/Online-Records.asp ) and were georeferenced to WA DNR Public Land Survey System (available at:<http://wagda.lib.washington.edu/data/plss.html>). The clipped versions (files with suffix ‘_clip’) were clipped to township boundaries for seamless mosaicing. The unclipped versions (files with no suffix) retain the original map collar and survey information.

Plat maps show streams, wetlands, and some land cover. They reliably reflect field data only along section boundaries and navigable channels. Within sections, the maps include many wet­lands with inde­terminate boundaries, and wetlands or smaller (non-navigable) channels that are drawn speculatively, sometimes in locations that are improbable or impossible. Familiarity with the instructions given to the field surveyors [see (White, C.A. 1991. A History of the Rectangular Survey System. U.S.Government Printing Office, Washington, D.C.) for compilation] is useful for map interpretation.
