Aquatic Vegetation Point Intercept Survey Report
4/19/2026
An aquatic vegetation point intercept survey was completed in Melody Lake on 4/19/2026 for the
City of Edina. The point intercept survey consisted of 49 points. A meandering delineation was also
performed to detect any additional curlyleaf pondweed not in the proximity of a site. At each site
depth was recorded and vegetation was sampled with a double-sided rake. For every species
sampled, an abundance rating was assigned based on how much was sampled on the rake. The
ratings are as follows:
0. Plant species absent
1. Plant species covers <25% of the rake
2. Plant species covers 25-75% of the rake
3. Plant species covers >75% of the rake
This rating scale was taken out of the Minnesota Department of Natural Resources Guidance for
Delineating Aquatic Plants for Management.
The table below shows all the plant species sampled during the 2026 survey. Curlyleaf pondweed
was not sampled. The most abundant plant species sampled was white waterlily. Average rake
abundance was 1.3, however, leaves were just starting to emerge. During the 2025 Melody Lake
Score Your Shore survey, white waterlily was extremely abundant, almost covering the entire littoral
area. This could have potentially outshaded all other species.
Species Frequency of Occurrence (%) Average Rake Abundance
Curlyleaf pondweed 0% 0
Elodea canadensis 12% 1.9
White waterlily 37% 1.3
Nitella spp 2% 1
