| Comments | weather clear, breeze. Surface water temp 22 C. Collected frequency data. No divers available, but collected a few biomass samples in shallow water by snorkeling in areas with flowering rush. Also collected hydroacoustic data on plant growth. The flowering rush seemed reduces in the treatment area, but robust in other areas of the lake, starting to emerge in shallows (but still reduced over pre-treatment growth, especially at north launch area). It was a warm winter and spring, so growth is advanced for this time of year. |
