The boy would go down to the lake with Doorknob, his Chihuahua. He'd stand by the water, hit reeds with a stick and tell them to speed up production. Like dad, Dorian had employees.

"The hypolimnion is the dense, bottom layer of water in a thermally-stratified lake. It is the layer that lies below the thermocline. (...) Being at depth, it is isolated from surface wind-mixing during summer, and usually receives insufficient irradiance (light) for photosynthesis to occur."
The thermocline is a shifting layer that separates the surface from the still, life- and oxygen-deprived water below.
Epilimnion, the top of a lake
Metalimnion, the middle layer (changes depth as the day rolls on)
