Impaired Waters and General Water Quality Reports

The Integrated Water Quality Monitoring and Assessment Report (including 305b and 303d)

The impaired waters list ("303d list") is now combined with the broader "305b" water quality assessment report to fulfill reporting requirements of the Environmental Protection Agency (U.S.E.P.A.) and the Maine State Legislature.

Draft Integrated Report. See Draft Integrated report for any draft report that may be available.

MAP 1 depicts the statewide distribution of 303(d) listed Maine phosphorus-based TMDL lakes (n = 31) within major drainage systems, classified by temporal groupings (Past EPA approved A & B, Current and Future studies). MAP 2 is a subset of MAP 1, and depicts the 21 (68%) phosphorus-based TMDL lakes which occurr in south-central Maine, including their names.
EPA's TMDL Program (off-site)

4/18/2000. A National Wildlife Federation publication, "Pollution Paralysis II, Code Red for Watersheds" looked at TMDLs and efforts to address NPS (non point source) pollution. It summarized results for each state and nationally, and gave each state a letter grade indicating how well it was cleaning up its waterways. Grades given were A, B,C, D and F. No state in the lower 48 received an "A" ("Good"). Only 6 of the lower 48 received a "B" ("Improving"). Maine got a "B". See http://www.nwf.org/watersheds/paralysis/index.html
