innehaha Creek quickly becomes dangerous during high runoff events and when creek discharge at Gray's Bay dam is higher than 150 cubic feet per second (cfs). See current Minnehaha Creek discharge rates on our homepage. Risk of illness and pathogens also increases during rainfalls and for 72 hours after rain stops. See our Water Pathogens Advisory for more information. Avoid the creek during any unsafe conditions.
| DISCHARGE (CFS*) | CREEK CONDITION |
|---|
| Less than 75 cfs | Poor |
| 75 cfs - 150 cfs | Good |
| Greater than 150 cfs | Dangerous |
* Cubic Feet per Second
The flow--measured in cubic feet per second--of water being released from the dam can affect canoeing conditions. Other factors affect canoeing conditions and safety, so please be sure to use good judgment and common sense at all times.
