Aquatic Vegetation Point Intercept Survey Report
4/21/2026
An aquatic vegetation point intercept survey was completed in Edina Lake on 4/19/2026 for the City
of Edina. Five species of vegetation were sampled during the survey (See table). The point intercept
survey consisted of 100 points. 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.
Below is a table of all plant species sampled in Lake Edina in 2026. Curlyleaf pondweed was not
sampled for the 3rd straight year. Elodea canadensis was the most abundant plant sampled at 25%
of the sites (see figure 1).
