Lake Diane
Lake Diane is a small, mucky-bottomed 'transition' type lake with fair to good water quality. Based on Lakewatch data, nutrient and algae levels in this lake are typical of a transition type lake and water clarity is therefore also typical of a lake of this type. Phosphorus levels range from 9 to 24 ppb (parts per billion) and average 17 ppb. Total nitrogen ranges from 360 to 870 ppb and averages 654 ppb. Algae populations, as measured by the chlorophyll concentration in the water, are low as a result of relatively low nutrient levels. Chlorophyll levels range from 2 to 22 ppb and average 7 ppb. Water clarity is good for this type of naturally 'stained' lake, as measured by the depth to which a standardized 'secchi' disc can be seen when lowered into the water. Secchi depths range from 2 to 4.5 feet and average over 3 feet. Water quality parameters showed a natural fluctuation over time during the two years during which water samples were collected.
