Creeks are runnable only after significant rain fall (ie. flood stage). Hazards include, but are not limited to strainers, low water bridges (nasty pour-overs at some levels), and narrow passages with tight turns. Be cautious, and paddle with someone that is familiar with these creeks! It is advisable to wear nose-plugs and be aware that the water quality is poor. Cases of Leptospirosis have been reported from paddlers playing on these creeks.
