#11917 23 Mar 2018 Approved Notes:

Tide was low and water was running quickly. It was not practical to use the Van Dorn for bottom depth analysis. Early attempts resulted in Van Dorn wrapped around pylon and seaweed at end of pier made alternative site problematic.

Measurements recorded form southern end of jetty.  Current too strong for use of the van Doorn.

Water level below bottom of gauge board.  Estimate -0.6m
