Local Environmental Conditions
Around Site C, the water's edge is thick with hazel and willow, whose pollen spreads readily in early spring, a short distance from here. Actual counts still shift year to year with temperature, rainfall, and prevailing wind. Local readings for the surrounding area tend to follow this same general pattern.
At Site C, the water-adjacent hazel and willow are early risers, getting an early start, typically cresting between February and March. Grass pollen builds through late spring and peaks in June, and then ragweed picks up the slack, running from mid-August through October. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

Pollen
| None | 0 | No or negligible risk of exposure. Pollen exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
