For the 2008 Integrated Report Cycle, the total assessed waters size is greater than the total waters size for the EPA Waterbody Type Lakes, Reservoirs, and Ponds in Washington. This discrepancy was identified after the release of the data, and is likely due to the improvements in mapping state waters.
