This is a picture of a section of the Ocmulgee River in Macon. We tested the amount of clams in different parts of the river. We also measured river depth from a starting point at the top of the hill. Each pin color means something:
Maroon: 0 clams found
Yellow: 1-4 clams found
Green: 5-9 clams found
Orange: clams found, but most or all were dead
Red: elevations of the river from the top of the hill above the river all the way across to the other bank.
The white line is the path of the measurements. The opaque polygon shows where there is now a high growth of bamboo on the sandbar.
