Aquatic Vegetation Point Intercept Survey Report
4/19/2026
An aquatic vegetation point intercept survey was completed in Hyland Lake on 4/19/2026 for the
City of Edina. The point intercept survey consisted of 73 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 species sampled during the 2026 Hyland Lake aquatic vegetation
survey. Curlyleaf pondweed was sampled at 21% of the 73 sites, with a average rake abundance of
1. The healthy native plant community in Hyland Lake may have been keeping curlyleaf pondweed
abundance down. Elodea canadensis was the most abundant species sampled during the survey.
Species Frequency of Occurrence (%) Average Rake Abundance
Curlyleaf pondweed 21 1
Elodea canadensis 67 2.4
Coontail 43 1.8
Chara spp 23 1.8
Flatstem pondweed 7 1
Small duckweed Observed throughout the lake
Large duckweed Observed throughout the lake
Forked duckweed Observed
