Searching for the name of a map

I was searching a map that was part of CS GO official maps pool or an operation a few years ago. It was set in a warehouse/jungle with a canal system underneath it.

I remember that either T or CT spawned outside and could enter the tunnel at spawn with the tunnel being in a "hole" that was reachable via a ladder or stairs.

There also was a part where you walked through a small river or something. I don't know what it is called and I couldn't recognise the map when searching through CS GO wikis. Maybe someone knows it :)
