Background reading: Lake Pontchartrain on Wikipedia
Set in Louisiana, Lake Pontchartrain is a 454,427-acre natural lake. At its deepest it reaches roughly 10 ft.
We read the level from USGS gauge 301200090072400, listed as L Pontchartrain at Crossover 4 near Mandeville, LA. Wind and weather come from the National Weather Service grid cell over the lake, so the numbers describe open water rather than the nearest airport.
On a lake this size the wind has miles of open water to work with, so a 15 kt breeze can stack up a steep chop in the main basin while sheltered coves stay flat.
The go or no-go calls above are a starting point, not a guarantee. Read how we score conditions, and always check local rules and posted warnings before you launch.
