Pond Boss Forums INTRO Questions & Observations Thermal control a new frontier in fisheries?

So would it make sense on a pond to use floating white plastic or wood to block the sun? Note that it would also knock down unwanted weeds, as well as cooling the lake, especially in that area.

there are limits, of course. Such a structure would block air mixing with the water, which could be a problem depending. Spawning beds need sunlight, too! But maybe we should be thinking harder about managing sunlight & heat, rather than just accepting the summer doldrums.
