An anchor assembly is included having a steel pole driven into the bed sediment. An open ring guide or a hollow, open-ended tube is attached to one of the three float assemblies and is intended to slip over the driven pole extending out of the water. Using this design, the floating evaporation pan may move freely around the anchor assembly due to wind, changes in stage, currents, etc., but still will maintain the pan in a level position upon the water body surface. | |
