Why the level can change

General factors for natural lakes like this

These are common influences for this type of lake. They do not identify the cause of a specific current change unless an operator update confirms it.

  • Rainfall & runoff

    Rain on the lake and watershed runoff can raise natural lake levels over time.

  • Inflows & outflows

    Tributaries, connecting waterways, and outlets move water into and out of the lake.

  • Evaporation & seasonal weather

    Warm, dry, and windy periods can increase evaporation and contribute to seasonal level change.

  • Ice, wind & seiches

    On larger natural lakes, wind setup, seiches, and ice conditions can temporarily change local water-surface elevation.
