DEEP: Proposed and Existing Maps

  Revised Water Quality Classification Maps

The water quality classifications mapping is revised to show the surface water quality classes by goal only – AA, A, B, SA, SB.  The proposal eliminates the tiered, or slashed, classification symbols (i.e. C/B).  Those symbols were used to indicate what a water body’s existing condition may be by the first symbol, followed by the “/” symbol and then the water quality goal. The revisions to the mapping symbols do not change the water quality classification goals, designated uses or criteria, or the management goals of any water bodies in the state.


The revision to the mapping symbols are being proposed to clearly indicate the water quality management goal and avoid any confusion with an indication of a presumed existing water quality condition.  The change to show the surface water quality goal only aligns the mapping with the ground water quality classifications symbols which were previously revised to show ground water quality goals only.  Also the classification mapping did not always accurately indicate existing water conditions, and existing water quality conditions or threats are more accurately indicated by the department’s available water quality monitoring and assessment reports and mapping or other potential pollution source mapping by the department.
