Waterfall · Burney, California
Camping nearby

President Theodore Roosevelt called it "the eighth wonder of the world" — Burney Falls is a stunning 129-foot waterfall fed by underground springs that produce 100 million gallons of water daily, maintaining its flow even in the driest months. Located in the 910-acre McArthur-Burney Falls Memorial State Park, the falls were designated a National Natural Landmark in 1954. The park offers camping, cabin rentals, boating and kayaking on Lake Britton, swimming, fishing, and 5 miles of streamside trails.

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.
