| Parameters | Range | Mean | TSI Value | Lake Grade |
| Months | June - Sept. | May - Sept. | ||
| Secchi Depth (m) | 0.5 - 1.8 | 1.1 | 59 | D |
| Surface TP (µg/L) | 41 - 155 | 80.8 | 69 | D |
| Chlorophyll-a (µg/L) | 3 - 237 | 61 | 73 | D |
| Overall Score | 67 | D |
The following summary refers to Figure 11.3 (a-c).
- Secchi disk depth was 1.3 m in the beginning of the season, and increased to 1.8 m in June. From July to August, secchi disk depth was below the standard limit (> 1.2 m) and increased slightly above the standard in September (1.4 m).
- Chlorophyll-a concentrations were below the standard (< 15 µg/L) in the beginning of the season. In July, concentrations increased to 15 times the standard limit (237 µg/L) and decreased to about three times the standard in August. Chlorophyll-a concentrations continued to decrease in September.
- Surface TP concentrations were just above the standard (< 40 µg/L) in the beginning of the season. In July, concentrations increased to 155 µg/L, about four times the standard limit, and then decreased for the remainder of the season.
