Allied Biological came Thursday June 19th and did a survey and treated with copper sulfate.
Text from the report (attached):
Truesdale Lake looks very good at this time. Unicellular algae only reducing water clarity to 5.5 feet. “Brown blobs” of filamentous algae were observed at the lake surface or suspended in the water column in a few scattered areas of the lake. No submersed plant growth observed during this visit. Water samples collected on 6/16/14 for algae ID and enumeration. Overall counts are low. Report is attached for review.
