Waterbodies that remain on the Planning List have potential impairments,<br />

but need further evaluation. A waterbody listed on the Verified List<br />

as impaired for a specific parameter may also be listed on the Planning List<br />

for a different parameter(s). They include<br />

Blackwater Creek<br />

Blackwater Swamp<br />
