Big Spring - Ozark National Scenic Riverways

Spring · Van Buren, Missouri
Camping nearby

The largest spring in Missouri and one of the largest in the world, Big Spring discharges an average of 286 million gallons of crystal-clear 58°F water daily into the Current River. Groundwater travels from sources up to 45 miles away, dissolving 70 tons of limestone per day. A wheelchair-accessible walkway leads directly to the spring. The former state park (1924-1969) offers a year-round campground, housekeeping cabins, a dining lodge, hiking trails, and summer campfire programs within the Ozark National Scenic Riverways.

About this map

Every pin is a live reading from a USGS real-time monitoring station, captured in a daily snapshot. Colours follow the site’s cold-water-safety thresholds and describe the water at that one sensor — usually a river or stream gauge, not a swim beach — so treat them as a guide to what the water is doing nearby, not a verdict on a specific spot. Readings are provisional and can be revised by the USGS. Your location only sorts this page: the coordinates appear in the address bar (rounded to about a mile) and are not saved to an account or our database.

Conditions are for general information only and can change quickly. Always judge the water in person and follow posted advisories and local guidance before swimming or paddling.
