In addition to the information on the condition of all waters in the state, tribal land, or territory, the 305(b) report should also provide information on which pollutants (chemicals, sediments, nutrients, metals, temperature, pH) and other stressors (altered flows, modification of the stream channel, introduction of exotic invasive species) are the most common causes of impairment to waterbodies and what are the most common sources of those stressors.

The report should also include a discussion of progress made toward meeting the CWA's goals since the time of the last 305(b) Report.
