Memorial Day weekend opens the boating season on most U.S. lakes. Nobody can tell you today what the level will be on May 31, 2027, so this page shows two real numbers instead: each lake’s level on Memorial Day 2026 (May 25, 2026) and its level now, from the same official gauges as our lake pages. It is rebuilt every day, so check back the week before the holiday, and open a lake page for the boating forecast.
