Notes

Sluggish dark brown outflow around mouth. Channel is against cliff but flow turns sharply east along beach face till it meets sand buildup from east a short distance from actual entrance & turns out to sea. A small sand bar continues to build up across the front of entrance from the cliff forcing the outflow to turn sharply between both areas.(about 4m. wide). Some waves from SW swell crossing over the small sandbar into the out flow the occasional one going up stream. Long shore drift also active

Many small fish around start of channel from estuary. ! dead Black Bream (stranded)
