This graph show the historical lake levels for the last 60 years. We’re still trying to corroborate the all time high during hurricane Jeanne in 2004 because of some conflicting stories about how high the water was and the way data was taken then. However, note the dramatic changes. Johns Lake essentially functions like a reservoir or large retention pond. The trend is higher for the past decade but there has also been some very dry periods in 2001 & 2002 with just pockets of water here and there. This data does not include the current 2020 year with the level as of 10/7/20 at 97.40 NAVD.
