Watershed Assessment Reports (305(b) Reports) and
Lists of Waters Requiring TMDLs (303(d) Lists)
Section 305(b) of the Federal Clean Water Act requires that states and
other entities prepare a Watershed Assessment Report to the EPA on April
1 of every even numbered year. EPA is required to summarize those reports
and prepare a report to Congress. State 305(b) reports are considered
a primary source (though not the sole source) of information used when
each state compiles its required list of waters needing TMDLs to reach
their standards that is also submitted to the EPA on April 1 of even numbered
years. The list is commonly referred to as the 303(d) list.
