Lake Levels

This page shows live data from three sensors monitoring the level of North and South Lake Leelanau – one at the dam in Leland, one at the narrows, and another at the south end of the lake. Looking for long term lake level and temperature data?

A few notes on the graphs:

  • The court ordered levels are measured at the dam (the green line).
  • The ordered levels are: level raised to 589.21 feet after April 15th or last ice and lowered to 588.21 feet after November 15th.
  • Both the high and low targets are measured at the dam.
  • You can use your cursor on the graphs to show detailed information in the lower left.
