2024 Water Quality Survey Results
In prior years, Clearwater Lake has been tested once a year. Understanding that a point in time does not give us a full picture, Clearwater Lake is now being tested monthly.

Based on the data they have in their database, the 10-year average for total phosphorus is 14 parts per billion. Your May result was 21 parts per billion (ppb), so slightly higher than average. This is not unusual for spring especially given all the rain we’ve had, which can wash sediment/nutrients into the lake and stir things up. Your chlorophyll-a result of 3.3 ppb is well below the 10-year average of 6 ppb. Chlorophyll-a is a measure of the amount of algae/plant biomass in the water. We tend to see this rise throughout the summer as water temperatures warm and more algae starts growing. |

Total phosphorus: May's result was slightly higher than average; not unusual for spring, especially given all the rain we’ve had, which can wash sediment/nutrients into the lake and stir things up. June results are in line with historical range. Chlorophyll-a: May and June results of 3.3 & 3.7 ppb are well below the 10-year average of 6 ppb. Chlorophyll-a is a measure of the amount of algae/plant biomass in the water. We tend to see this rise throughout the summer as water temperatures warm and more algae starts growing. |
