Swimming and boating at Twin Lakes Reservoir

Low water changes a lake fast for boaters. Some ramps get shorter or close, docks may be moved, and rocks and sandbars that are usually well under the surface come within reach of a prop.

If you swim, pick a spot with an easy way out, and remember that drop-offs move as the level changes.

How we check values

Each reading is stored as published. We hold back values that jump faster than physically plausible and show the measurement time with every value.
