Aquatic Vegetation Point Intercept Survey Report
4/26/2026
An aquatic vegetation point intercept survey was completed in Indianhead Lake on 4/26/2026 for
the City of Edina. The point intercept survey consisted of 100 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.
Four species of vegetation were sampled during the survey in 2026. Curlyleaf pondweed was not
sampled in 2026. The most abundant species of vegetation was Chara being sampled at 95% of
sites with an average rake abundance of 2.7. Leafy pondweed was sampled at 3% of sites. Leaf tip
and absence of glands were used to identify leafy pondweed.
Species Frequency of Occurrence (%) Average Rake Abundance
Curlyleaf pondweed 0 0
Chara 95 2.7
Leafy pondweed 3 1.6
Filiform pondweed 1 1
Coontail 1 1
