Commentsnative mussels, otter family, osprey and nest. We were here to do the 1 year post-herbicide plant sampling. No sign of M. spicatum, the only plant evident was Egeria (and P. zosteriformis at far north end), Egeria was mostly black - though many were green in the middle of the stem. Some had green shoots. The lake is very muddy colored.
