I was fortunate to be asked to sub for a very pregnant Mrs. Walker on Target's field trip today to Sope Creek, part of the Chattahoochee River National Recreation Area. Our Park Ranger was Mr. Jerry Hightower, who first taught me about the Chattahoochee River Watershed over 10 years ago! The students were able to search through leaf litter to find macroinvertebrates, indicators of the health of Sibley Pond, and by extension Sope Creek and the Chattahoochee River. The more biodiversity, the healthier the water! It didn't look healthy today though, as much needed rain brought silt into the creek from the surrounding areas.
