In late fall 2023 the Harrisons Bay Association in partnership with the LMCD hired Carp Solutions to do a carp population assessment on Harrisons, West Arm and Jennings bays. The results were staggering. A healthy level of carp for an ecosystem is 100 lbs/acre. Here are the results:
Calculating this out for all 3 bays it means over 700,000 lbs of carp in the 3 bays! We are looking for volunteers from West Arm and Jennings to help us tackle this issue and lobby the agencies for more attention to the problem.
High populations of carp disrupt the sediment in the lake and release phosphorus that leads to algae blooms, they disrupt feeding, spawning and nursery habitat for game fish and they uproot native vegetation.
HBA has received grants and provided money to assess the carp population and track spawning behavior up Painters Creek.
Here are the plans for additonal donations:
Did you know that there are over 2000 species of carp (Cyprinidae) across the world? The common carp (Cyprinus Carpio) grows up to 47 inches and 88 pounds.
Carp were introduced as a game fish by early settlers as far back as 1880 and have long made Minnesota waters, including Lake Minnetonka, their home. Concern around their negative impact to our natural, amazing waterways in the last 10-15 years has increased dramatically, and for good reason.
Carp represent a risk to our water quality across the lake, but specifically in Harrisons Bay, in several key areas:
