Florida spring

Spring Creek Rise Main

Spring Creek Rise Main is a first-magnitude submarine spring known for its clear, 72-degree water and a flow of about 2,000 cubic feet per second (1.3 billion gallons per day). Set in Spring Creek near the Gulf of America, its 100x35-foot basin—up to 100 feet deep—offers a unique spot for scuba diving, surrounded by marsh islands and oyster bars. Accessible only by boat from Spring Creek ramps off CR 365, it’s in a public waterway but requires navigation skills. Summer weekends draw divers—arrive early for calm. For quiet, visit weekdays in spring (April-May) or fall (September-October), mornings ideal. Water clarity is typically vivid but can cloud with tidal and river influences. Check —stable, low salinity levels around 1-2 ppt enhance visibility, clearest from late fall to early spring during dry periods.
