Berkeley Lake Aeration/Fountain/Bubblers

Anyone have any information on what’s going on at Berkeley Lake? They installed what looks like a boat ramp, then a pontoon boat arrived, now there are some machines creating bubbles across the lake. Water quality device? Oxygen machine for aquatic lizard people? Denver’s Bellagio Fountain? I can’t find anything online.

Seriously hope it’s for improving water quality. It would be so cool if the lake was clean enough for dogs to swim in. Or dare I dream of a day when it’s safe for humans to swim in.
