The Cataract River is a seldomly run river, with the best sections of river being SCA land and inaccessible (upstream of the broughton pass weir) .The accessible section (below the weir), has some good rapids in it, of grade 3 standard with one grade 4, however the river is heavily overgrown with small trees / shrubs and some sections are inpassible and difficult portages through heavy scrub is necessary. The standard increases significantly in high flows (Above 0.4m on the gauge). About 500m from the start there is a portage at normal low flows (0.2 - 0.3m). About 3km from the start, there is a 3m fall right across the river onto rocks - which should be portaged. Many problems with trees / shrubs will be encountered downstream. The river in this section flows through an impressive gorge. At the end of the gorge, where the Cataract River joins the Nepean, turn left and paddle 1km upstream to Douglas Park Bridge. A big flood needs to go through to clear out the rapids to make the river worth running again. There are a handful of clean small rapids, but genearly this is not worth doing as other better rivers nearby will be running if the Cataract is up.
