A device for detecting leaks in containers that are open to the effects of rain and/or evaporation comprising an outer cylinder or container partially submerged in a container or vessel to be measured, such as, a swimming pool, three adjustable legs attached to the bottom of the outer cylinder, an inner tube having a bottom edge fastened to the bottom, an outer, floating guide cap, and an inner floating indicating rod. The device is placed in a swimming pool and submerged to a selected level. The inside of the outer cylinder is filled to a particular level and the relationship of the floating indicator rod and the guide cap is recorded. Periodically, the level is checked to see if there is a change in the level due to a leak in the pool or container. The relationship of the floating indicator rod and the guide cap indicates a net leak in the pool or vessel being tested.

An improved evaporation pan assembly having at least three float assemblies attached to the outer side wall of a circular shaped evaporation pan located in 120 degrees increments. 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.
