It has dropped 0.04 m over the past 24 hours. With the water still dropping, the shoreline keeps moving out. In the last month it has stayed between 45.14 m and 46.01 m.

Many reservoirs are drawn down through summer and fall; most of the refill comes later, with winter rain or spring snowmelt.

A receding shoreline opens up beaches but also uncovers hazards: stumps, rocks and soft mud that are usually well under water.

Wear a life jacket on the water. Most boating deaths involve people who were not wearing one.
