Local Environmental Conditions
Hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen, within the neighborhood's edge. 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. Ground-level conditions like local landscaping can nudge these figures slightly either way.
Water-edge hazel and willow are usually the first allergenic trees active here, topping out well before most other trees start releasing pollen, around February and March. Moving into early summer, grass pollen climbs to its seasonal high in June, with ragweed climbing to its own high point from mid-August through October.

Are pollen levels in Okaw Valley Kampground based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Okaw Valley Kampground, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

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. |
