Aquatic Plant Survey

2025 Survey Results

On 24th of July 2025, 337 points were observed and sampled for aquatic vegetation. The weather was conducive for the survey with sunny skies, temperatures reaching 78 degrees and little wind. Water temperatures were 75.5 F degrees. Sampling occurred to a maximum depth of 28 feet; however, no plants were found to be growing beyond 17 feet of water. Plant abundance was greatest between two and ten feet of water. As depths increased beyond that range, the presence of vegetation decreased and became less dense (Figure 4).

The maximum number of species found at a site was seven. Twenty four different types of native plants were found across the sampling area while no invasive species were present at the predetermined points. Of the 337 sampled locations in East Battle Lake, 27 sites had no vegetation present. The most abundant native plant species were chara (Chara sp.), Coontail (Ceratophyllum demersum), and Bladderwart (Utricularia vulgaris).
