Sixth Level Sub-watersheds as Basis for TMDL AssessmentsPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Pp. 485-489 in Total Maximum Daily Load (TMDL) Environmental Regulations: Proceedings of the March 11-13, 2002 Conference, (Fort Worth, Texas, USA) 701P0102.(doi:10.13031/2013.7600)Authors: Ranjan S. Muttiah, Gary Coutu, and Mark Gaber Keywords: TMDP spatial unit, Digital Raster Graphics (DRG), Digital Ortho Quarter Quads (DOQQ), elevation maps, National Instruction 170-304 It is argued that 6 th level sub-watersheds which range in size from 4-16,000 hectares (10-40,000 acres) is suitable for TMDL assessment of river segments. Our basis for doing so are the following: 1) the sub-watersheds are being consistently delineated nation-wide according to Federal Geographic Data Committee (FGDC) guidelines, 2) the sub-watersheds are appropriately matched for the widely recognized 1:24,000 scale local maps, and 3) sub-watersheds can be used to estimate relevant water and transport processes relevant to TMDLs.
