| Comments | From report: Aquatic Plant Survey Report for Crystal Lake (Middletown, CT), Prepared for the Pond and Lake Connection, December 21st, 2021
Data from an herbicide pre-treatment survey. Since 2019, there has been a steady decrease in curly-leaf pondweed abundance during the pre-treatment surveys. During the April 8, 2021 survey most of the plants reached about 1/3 to 2/3 of the water column in height. The Curlyleaf pondweed plants were much lower in the water column in the 2020 and 2021 pre-treatment surveys than in the 2019 pre-treatment survey. In 2019, the plants were almost always just beneath the surface or breaking the surface of the water. It should be noted, however, that the 2019 pre-treatment survey was conducted on May 1st, much later than the March 24th, 2020 and April 8th, 2021 pre-treatment surveys. |
