A draft of a state report shows there are more portions of Alabama's lakes and streams that are dirty or polluted than four years ago.
The report found the number of Alabama's polluted or oxygen-deprived stream and lake segments grew from 181 to 210.
Tributaries and portions of the Cahaba River in Birmingham were added to the list.
States are required under the u.s. clean water act to identify lakes and streams not meeting water standards.
After a state lists a lake or stream, the state is required to develop a plan to clean it.
