Item Definitions for Sole Source Aquifers
IMPORTANT: You must reselect AQ_STATUS NE 'X' and AQ_CLASS NE 'X' in order
to see the true aquifers. There are some polygons in the coverage
that are not aquifers. You must unselect them.

Data assembled by Randy Deardorf ca. 1995; another aquifer added by Ray Peterson 2003. We believe Randy digitized the boundaries of the aquifers.

Loaded boundaries of new Troutdale Aquifer System, Vancouver, WA These are based mostly on 1:24,000 scale digital geologic map, from Washington DNR.
Snapped some boundaries of Spokane-Rathdrum and Eastern Snake River Plain Aquifers to Idaho 10-digit HUC boundaries where coincident

OEA-095
Snapped shoreline boundaries of Central Pierce County, Vashon-Maury, North Florence Dunal, Cedar Valley and Whidbey, Guemes, Marrowstone, and Camano Islands to USGS 1:24000 scale hydrography shoreline data. Snapped partial boundary of Newberg area aquifer, along Pilchuck River, to USGS 1:24000 scale hydrography stream data. Also adjusted Cedar Valley aquifer boundaries, where appropriate, to coincide with alluvial floodplain boundaries as evidenced on Washington DNR digital geologic map and also by using 10m digital elevation model data. The Cedar Valley source area boundary was adjusted to conform to 8-digit Washington hydrologic unit map boundaries, where appropriate.
