Oliver County Lake Quality
North Dakota, 4 lakes, measured by ND DEQ
Oliver County holds 4 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. 3 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. For Oliver County the spread behind the average matters more than the average itself: a few nutrient-rich lakes among many clear ones produce the same figure as the inverse.
The county's lakes lean shallow, which makes the readings sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest measured lake is East Arroda Lake.
