Estimated depth 0.7m in wetland - below the bottom of the markers, extremely low, not flowing out. Monash Freeway works have not reinstated the creek yet. However, recent flooding was over the creek banks - apparently the wetlands have both drained and dropped well below the outlet in a very short period. Only reason I can think of is that the wetland is draining out of the inlet pipe back into the very low creek.

THe pH was 6.5 using PR, so retested with CPR and got 6.8.
