After finding the Bark River covered with duckweed, we decided we would try putting in on the Rock River in Jefferson and paddle the short distance upstream into the Crawfish River. However, there was a sign at the old landing on the Rock River in Jefferson that read “For Emergency Personnel Only.” Apparently the public now has to use a different landing 1/2 mile further downstream where big boats more likely to be present, and also we felt it would be too far to paddle upstream to get to the Crawfish. Therefore, we got back in the car and proceeded to Aztalan State Park. Temperature 80° light wind.
Flow Crawfish River at Milford gauge 05426000: 189 cfs. (median ~110 cfs) We later found we had made notes in the margin of Paddling Southern Wisconsin that we “should not do the Crawfish if the flow at Milford is <310 cfs," notes we had made after an Aztalan to Jefferson paddle several years ago. However, we didn't have the book with us, or we might have just called it a day. The trip: In at 4:45 PM, upstream one hour to I 94, out 6:30 PM. Shallow, near-grounding once, glanced off rocks near landing. Wildlife: kingfishers, herons, turtles, plover, swallows, cranes in flight, jumping fish.
