The Red Lake River State Water Trail is nearly 200 miles long, stretching from Lower Red Lake to the confluence of the Red River of the North in East Grand Forks. Residential development is extensive along the shoreline through the Thief River Falls Area, but below St. Hilaire the banks are densely wooded. Between St. Hilaire and Red Lake Falls the river drops 110 feet so class I-II rapids are present, flanked by steep eroded cliffs. Few portions of the river are suitable for motor use but the river is very popular for paddling and tubing. The St. Hilaire City Park includes a trailer access point as well as carry-in access.
This section of river is prone to flooding in spring, hence the cache name, but it should be safe from being washed away. The cache is good sized but well camoflaged, and is easily accessible by land, water, or ice. There is far more wildlife activity than muggle activity in the park but stealth might still be required!
Congrats to UpNorthTD on being FTF!
