MLPMD Point Intercept Aquatic Plant Survey 7/7/2026

Onterra was once again on Mid Lake to perform the Point Intercept Aquatic Plant Survey on July 7th. This is the next step in the update of our Aquatic Plant Management Plan.

While there are many aquatic plant sampling methodologies that have been developed and used over time (i.e., transect surveys, biomass surveys,
SCUBA surveys, quadrat surveys, etc.), utilizing a standardized and repeatable point-intercept based sampling methodology allows data to be compared over time. The protocol uses a point-based sampling design, with sites located on a geo-referenced sampling grid laid out on the surface of lake. Sites are sampled from a boat using a double-sided rake, and information on depth, substrate, plant abundance and species identification are recorded at each sampling location. The consistent statewide effort of monitoring aquatic plant communities using a standardized methodology results in an enhanced ability to understand and manage them. For example, monitoring data are used to assess the relative health of a plant community and guide management actions.
