Dodge County Lake Quality
Wisconsin, 3 lakes, average grade D (Poor)
Only 3 lakes in Dodge County carry an active grade. The county-level summary is therefore representative of those specific lakes, not necessarily of every water body in the county. The county-wide average grade is D — water quality issues are persistent across most of the monitored basins. 1 lakes fall into the F bracket outright.
The county's lakes lean shallow, which makes the grades sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest lake on the books is Lake Emily (B); the most-stressed is Beaver Dam Lake (F).
