#10525 6 Oct 2016 Approved Notes:

Monitored from Sth end of jetty.  Strong outward flow meant tha the weighted rope and the Hach leads were not vertical, but on an angle.  So depth measure are not precise.

Bottom sample could not be collected due to strong flow.  Van Doorn not suitable under these conditions.
