Elkhorn Lake spans 79 acres and reaches a maximum depth of 41 feet. Known for its recreational value and clear water, the lake is currently classified as non-impaired due to its low nutrient levels and overall stable water quality. While it exhibits some characteristics of a eutrophic lake—such as occasional nutrient fluctuations—Elkhorn continues to demonstrate generally strong ecological health.

Long-term monitoring reveals some emerging concerns. Total Phosphorus (TP) levels show a slight upward trend, though they remain well below state impairment thresholds. Total Suspended Solids (TSS), likely influenced by runoff and erosion, are also increasing but continue to stay within acceptable limits. Chlorophyll-a (Chl-a), a key indicator of algae growth, meets state standards, and Secchi depth measurements indicate low turbidity and good water clarity.

These indicators suggest that Elkhorn Lake currently supports a healthy and resilient aquatic ecosystem, though ongoing attention is essential to prevent future decline. The surrounding land—including forests, wetlands, farmland, and developed areas—plays a significant role in influencing the lake's water quality through nutrient and sediment runoff.

To maintain and protect these favorable trends, it is important to continue regular water quality monitoring across various locations, implement sustainable land management practices, and promote active public involvement. With continued stewardship, Elkhorn Lake can remain a vibrant natural resource for generations to come.
