Thanks I appreciate the reply. After re reading it I acually think I have a rough idea. The water from the enchanted lake is used as coolant, and looking through the instructions for the control rooms, a blue button floods a corresponding crystal room with gas coolant. I believe the tiny holes in the walls of the crystal room then automatically ventilate the gas coolant into the reactor it's connected to. After the reactor is used the silo cools, the gas coolant turns to liquid, and its subsequently flushed down into the caves.
Something like that? Although I doubt it will happen, if my players ask how the gas coolant from the lake is entering the crystal rooms when a blue button is pressed, I can explain it as coming from pipes and unseen machinery converting the lake water to gas within the walls of the crystal rooms.
The only thing that's unclear to me is some of the detail around the crystals. The cavernous parts of the crystal rooms have small uncharged crystals embedded in the walls (and a few that are egg sized). There are also oon scouts in the black crystal lab that have mining equipment, which led me to think they were responsible for mining the uncharged crystals. I have a player with a secondary skill as a jeweler and I'm almost certain he'll ask about the crystals, likely with the the intent to occupy the facility at the end of the adventure. Although if/when he learns about chalak these plans will probably change.
