LAKERS TOGETHER: Grand Valley is preparing for successful learning experiences when classes resume on Aug. 31. Learn more about the plan for fall in this handbook.
Mona Lake is a drowned river mouth lake, located in Muskegon County, which drains directly into Lake Michigan. The lake faces some serious water quality challenges, including: severe chemical and biological degradation, contaminated sediments, high phosphorus loading, and nuisance algal blooms.
The phosphorus that helps fuel the algal bloom can come from both the watershed (via tributaries and atmospheric deposition) and the lake sediments. The latter process, often referred to as internal loading, is recognized as potentially important in nutrient-rich lakes, but is much less frequently measured than phosphorus sources from the watershed.
The results from this study will be used to promote water quality in the Mona Lake Watershed in the following ways:
In addition to providing data for local decision making, the proposed project will utilize a methodology that can serve as a model for the assessment of internal vs. external nutrient loadings in a watershed. This assessment is critical in determining the source of impacted nutrients, which can help optimize resource allocation for surface water improvements.
