Nest Lake, encompassing a surface area of 969 acres and reaching a maximum depth of 40 feet, is a valued recreational resource known for its clear water and generally low algae levels throughout the open water season. Its good water clarity and overall water quality make it well-suited for swimming, boating, and other lake activities. Clarity monitoring of George Lake began in 1972, and additional water quality parameters have been consistently tracked since 2004.

Nest Lake continues to demonstrate good water quality, meeting Minnesota Pollution Control Agency (MPCA) standards across most measured parameters. The lake’s Total Phosphorus (TP) levels are higher that MPCA standard, indicating the need for continued monitoring and responsible land use practices. It does show a promising downward trend, indicating potential stability in nutrient management and improvements. Total Suspended Solids (TSS) remain within the standard with a downward trend suggests low concentrations of suspended particles leading to better water clarity. Chlorophyll-a (Chl-a) levels fluctuate overtime but have remained within acceptable limits until 2024. This raises the importance of reducing nutrient loading and maintaining vegetation buffers. Secchi depth readings showcase excellent clarity and reduced turbidity, underscoring the lake’s strong overall health. According to the Trophic State Index (TSI), Nest Lake is categorized between moderately clear mesotrophic and green eutrophic, meaning it exhibits average nutrient enrichment and normal water quality. 

To sustain these positive trends, it is crucial for the community to remain proactive in conservation efforts. Continued monitoring, responsible land management, and public engagement will help ensure that Nest Lake remains a thriving ecosystem for future generations.
