General Description: The first 3 km to Liena Bridge is grade 1. The remaining 13 km cuts through the middla of Standard Hill and is grade 3-4. There is a very difficult section of rapids about the middle of the trip where the river drops 40 m in 1 km (Grid ref. 378 036). Extreme caution must be taken as the walkout is very difficult. The first drop is easy Grade 4 before a steep sided gorge ends in a 3 m drop. Take a rope to assist with portages. These may take some hours but usually the main drop can be portaged on the right hand side from a small eddy. At lower water heghts there is usually a log in the main shoot of the drop which necessitates a portage. At medium water heights a portage on the left hand side across the rock shelf is feasible but make sure the eddy above this rock is reachable.
