- Secchi Disk (2014): No data available for 2015-2016. The average summer secchi disk reading (Deep Hole) was 8 feet. Southeast Georegion average = 6.6 feet. Typically, the summer water in 2014 was reported as clear and BEAUTIFUL – could not be nicer.
- Chemistry (2014): No Chlorophyll data available for 2015-2016. The average summer Chlorophyll in 2014 was 5.1 µg/l (compared to a Southeast Georegion summer average of 28.4 µg/l).
- Chemistry (2016): The summer total Phosphorus average in 2016 was 22.7 µg/l. Lakes that have more than 20 µg/l and impoundments that have more than 30 µg/l of total phosphorus may experience noticeable algae blooms.
- Trophic State Index (TSI) (2016): 52/Eutrophic. What does this mean?
Eutrophic lakes are high in nutrients and contain large populations of plants, algae, and fish, which often grow to nuisance levels, and the fish species are generally tolerant of warm temperatures and low oxygen conditions. Phosphorus can fuel algae blooms. This TSI usually suggests decreased clarity, fewer algal species, oxygen-depleted bottom waters during the summer, plant overgrowth evident, warm-water fisheries (pike, perch, bass, etc.) only.
Based on Wisconsin DNR data from 5 volunteer readings taken on different days in July-Aug 2014 and volunteer and paid private readings on 2 days in March and August, 2016.
