VLAWMO capital improvement funds have been used in this effort. Licensed and permitted contractors conduct fish surveys and harvests.
There are several species of bullhead that are native to North America. Each type of bullhead stir up lakebed sediment and uproot aquatic vegetation through their bottom-feeding habits. Nutrient-rich sediment that gets stirred up can increase the frequency and duration of algae blooms. Because of their negative effects on water quality when bullhead abundance is high, harvest is a common strategy to support game fish populations and improve water quality.
Goose Lake in White Bear Lake is on the State Impaired Waters list for high levels of nutrients. It has been the watersheds goal to try to reduce these nutrient levels for in-lake as well as downstream water quality. Studies have determined that internal TP loading is affecting water quality – disturbed lake sediment releasing high levels of nutrients into the water column. Rough fish, such as carp, sucker and bullhead, forage in lake sediment while feeding. Large populations of these fish can cause problems in lakes due to the amount of sediment and nutrients these fish stir up in their daily feeding.
Fish surveys were conducted in 2012, 2017, and 2019. A 2021 survey is being done with results expected in early 2022.
Fish management is an ongoing pursuit connected to supportive efforts such as establishing game fish habitat with aquatic vegetation.
