Dwight, I agree the decreased clarity is likely due to an algae bloom from the week of increased light penetration...If the decreased clarity is in fact due to a bloom, should there be a concern of a near certain die-off of the algae and consumption of oxygen now that the pond is snow covered and has reduced sunlight again?
In previous winters it hasn't been a problem though that is no gaurantee.
I think that these winter blooms are pretty weak since the water is still very clear. The clarity is still at least 96 inches.
