50th and Not 50th are alright drains. They're not the longest or most exciting but they are fairly accessable by PT and make for a not bad day out. There isnt too much to say so Ill let the photos do the talking.
The best way to do these two drains is go through the inflow of Not 50th and then come out the outflow and walk 5m upstream and head in the outflow of 50th up to the inflow as these drains are right next to eachother.

50th is just 800m of 3m RCP with a cool inflow that always makes for some wicked photos.




The water at the outflow is about knee deep and eventually gets dry. From here the drain just continues as large featureless RCP until the inflow. Despite it being the middle of winter and freezing cold a bunch of the toads decided to slide down the steep ass ramp. It made for some real good videos.
