About Sioux Harbor
38.92942° N, 90.34680° W Normally, this small harbor is well protected from flooding and storms. The owners are boaters; they are incredibly helpful & polite, and they treat everyone equally. This area has many sailboats and a lovely pump out station! The depth is well maintained, often around six feet in a pool. The charming town is peaceful, quiet, and home to friendly locals. The store and restaurant/bar are only a short stroll away. The docks are sturdy, well-maintained, and safe.
