Local Environmental Conditions
This area, within easy reach, has the waterway's edge supports hazel and willow, species known for potent, wind-carried pollen. Small shifts in elevation or soil type can move these figures a little either way. Neighboring areas with similar land cover tend to show a closely matching pollen mix. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
Hazel and willow along the water get the season underway before other species, climbing steadily from late winter into March. Moving into early summer, grass pollen climbs to its seasonal high in June, with ragweed then rising to the fore from mid-August through October. Neighboring parts of the county typically see this same sequence with only minor timing shifts.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
