I have never trapped any but have read a little about it. Are there any beaver dams in the creek? If there are otters will use the crossover on them and a 330 conibear on the downstream side of the dam at the bottom of the crossover is supposed to be a good set. You can also make dirtholes along the creek with a bedded 1 1/2 coilspring trap baited with fish. Good luck keeping the coons out of that though.
