OBSERVATION & NOTES : What has changed since last time you monitered - More Oxygen Better EC. What stands out about the site today - Muddy apperance of water & losts of Algea in macro sample. Also lots of grass lash in macro sample aftera patch of bank had been mowed and sprayed. Large tree branch blocking one of the tunnels under the road. Phosphate - If using Lamotte Smart2 Colorimeter multiply by 0.326 to calculate mg/L - Poor.
