Ebin G Fine park is the whitewater park. Easy raft access is off Canyon, right before it turns and climbs up the canyon proper. No ramp. 100+ yard carry.
I think you'd be fine in a bucket boat, but you might want an extra bucket.
East side of 30th st, river right is easiest take out, but it is a university lot that you shouldn't park in until after 5 pm. There is parking on the west side, bit it is a longer carry from the river.
