#5181 23 Feb 2011 Approved Notes: Strong downstream current.
Overcast, mild, light wind.
Lead too short to reach 1.8m ie 10cm above bottom sample.
Require Van Dorn for top and bottom samples

#5328 23 Mar 2011 Approved Notes: Conductivity (12.81mS/cm) - checked at ambient/room temperature.
Outward current was very strong.
Top-bottom sampling was not possible. Jetty -water distance too great to use sampling bottle on pole. Hence no turbidity or pH readings.
Probe leads also too short to make readings at deeper depths

#5421 18 Apr 2011 Approved Notes: Water too low to reach with bottle on pole at this site. Thus, turbdity and pH not recorded.

#5541 23 May 2011 Approved Notes: Top sample for turbidity and pH taken at shoreline adjacent to the jetty.
Sampling form jetty not possible with sampling bottle on pole. Bottom sampling not possible either.
Although low tide was some 20mins prior to monitoring, the current was still flowing out.
