This is one of those recently built greenfield drains that although its walkable, kinda sucks.
Entrance: 1.9m
Materials: Concrete
Shapes: Round
The inflow to froglocker is a bit of a tricky one, you have to lift and move the smaller grille piece while balancing on the dam wall. We did this in summer but I could imagine when the dam fills up and it gets wetter standing on here may be harder.
The big room is a pretty nice space to be in. The bigger 2.1m pipe leads downstream to the flooded outflow. The other pipe leading upstream heads to a grille room.
The grille is a short walk from the big room and has two 1.2m RCP pipes that sprawl out before shrinking. I think you can open one of the grilles here but I didnt have a good look.
This small patch of dirt looks like its just dirt, but it is actually a knee deep pit of silty clay ridden mud! I found that out on my own coming here, it is deceptively sloshy. The outflow to this drain seems to be sunk 1m or so below the actual drain so its flooded and filled with trash, much like other greenfield drains around the newer suburbs. LCD and the Williams landing drains are good examples of the same problem, but much cleaner.
