There are plans for a website, social media presence, letter, door to door information all in an effort to educate about the creek.
Yup, that'll fix it.
How about going upstream and talking to the guys who dump shit into the creek like the farmers of Oxford?
That's where the problem comes from predominantly...livestock runoff, improper nutrient management on the farm, and of course, the usage of risky pesticides and insecticides that runoff into the local fresh water supply.
Hanging some pictures up and leaving junk mail at peoples' door won't do anything. How about big fines for dumping...in the hundreds of thousands...and bigger fines for recidivists.
