The shaded polygons in the map above represent Maryland’s 8-digit scale watersheds. The delineation breaks the state up into 138 watersheds whose boundaries generally represent drainage divides between 3rd order rivers or streams. These watersheds are identified via an 8-digit numeric code. The 8-digit scale is the most common management scale for watersheds across the state and therefore is the scale at which most of Maryland’s local TMDLs are developed. Watersheds in this map relate to TMDLs and WLAs in the applicable queries via an 8-digit watershed name identified in the location description.
