What these statuses mean
Use caution: Flow is well above normal for the date. Water is likely fast and strong, wading is likely unsafe, and floating generally calls for experienced boaters. Check local reports and consider waiting.
Blown out: Flow is among the highest this gauge records for the date. Expect fast, high, probably discolored water that may carry debris. Most anglers and boaters will want to wait for it to drop, so check local reports.
These are automated comparisons with each gauge's own history for the date, not safety ratings. Never use this page to decide that water is safe.
