Total Maximum Daily Loads (TMDLs) are required actions for polluted waters found on the Alaska 's 303(d) List of Impaired Waters. DEC lists these waters in Category 5 of the Alaska Integrated Water Quality Monitoring and Assessment Report, which encompasses the 303(d) list. The waterbodies shown here have an approved TMDL in place.

A TMDL, or other approved management mechanism, are required for a polluted waterbody to be removed from the 303(d) list. A waterbody can also be removed if there are assurances that pollution controls are in place, or will be in place that result in attainment of water quality standards. These 'assurances' include other pollution recovery plans such as a waterbody recovery plan, Memorandum of Understanding (MOU), Record of Decision (ROD) or a similar type of hazardous substance clean-up approved by DEC's Contaminated Sites Program. These waters are shown in Category 4b of the Integrated Report. There are also instances where there is no true plan but general assurances that controls are being implemented and only require some follow-up implementation or effectiveness monitoring (as opposed to in-stream monitoring).
