The Lily River put-in is no longer used as commonly as the Hwy 52 west put-in, just downstream from the blue suspension bridge. (Lily River enters on the left, just 0.2 mile downstream.)
The character of the Wolf River changes south of Lily. Upstream you'll find a marshy, winding and mostly quietwater river. Downstream, the Wolf become the classic boulder garden river for which it has become known.
There are two Class II rapids and a few Class I riffle rapids in this short, 3.5 mile stretch. At about 2.5 miles you'll reach _Big Slough Gundy_, a low Class II rapid in a wide stretch of river. Less than a mile later, _Little Slough Gundy_ is a Class II rapid through a beautiful narrow stretch, with a couple of small ledge drops.
The recommended take out is at Wolf Road, just after Little Slough Gundy, on river left.
For those continuing on for the 'full reach', the remainder of the distance to Hollister Road (the normal put-in for the next section) is flatwater and light (class I) rapids.
For those interested in history, logging era timber is commonly seen on this stretch. Those willing to put in the time can find timber company brands burned into the ends of eight-footers that haven't rotted away.
