Kayaked in from Storm Ranch then traveled 4 miles S to middle of mile 89. Walked N and S from there. Kayakers should be aware of duck hunting along the river this time of year. River is breached near outlet of Floras Creek. No significant activity - beach was pretty clean. White foam - mostly just small wood pieces and a few shells in tideline. Northern Harrier, hunting over beach. Other birds seen were: Western Sandpipers, Buffleheads, Common Mergansers and gulls. Tracks of an adult fox with young on beach. 3-4 very large light bulbs washed up on beach. Low human impact (0).
