Current status from this report
Discharge or advisory reported not linked to a mapped water: Official advisory in effect. Current rule period ends Nov 20, 2026, 2:41 AM CST. This is not a water-quality test.
Why this status: Discharge or advisory reported: official advisory.
Why we use this rule: An official advisory is listed. We show it while the authority keeps it in place; an old or missing update does not mean the advisory was lifted.
A report is not a test of the water. See how we assign statuses.
