Green Water Blues
The sun rises over a field west of Hoffland Dairy near Clayton, Mi. The Rice Lake Drain, a tributary of Bear Creek, which flows into Raisin River and eventually Lake Erie, is thick with green algae and duckweed. Stationed in the field is the traveling irrigator that Hoffland Dairy uses to pump liquid manure from their lagoons to these fields. Scientists point ot the runoff from the liquid manure for the algae-producing phosphorus pouring into the lake.
