About the report

This study monitored turbidity, water chemistry, macroinvertebrate and fish community structure and condition factors of two fish species in 1996 for two months before the creek crossing was opened to tourist traffic early in the Dry season (24 June) and for 4 months afterwards. A modified BACIP experimental design was used, which included paired sites in both Jim Jim Creek (upstream and downstream of the road crossing) and Twin Falls Creek (a control stream, with analogous but undisturbed upstream and downstream sites).
