at Johnson's Shut-Ins State Park
The following flag system is designed to inform visitors of the water level that is flowing through the shut-ins and access to the area for swimming/wading activities. The water level is monitored by a river gauge. River flow is measured by cubic feet per second (cfs).
Red Flag (75 cfs and higher)
River Flow At High Hazard Level: Shut-ins access gates are closed.
Yellow Flag (26 - 74 cfs)
River Flow At Medium Hazard Level: Shut-ins access gates are open.
Green Flag (25 cfs and lower)
River Flow At Low Hazard: Shut-ins access gates are open.
