Local Environmental Conditions
In Lower Campground, located just outside the immediate area, this area has the water's edge is thick with hazel and willow, whose pollen spreads readily in early spring. This area, close to this spot, has green space with maintained lawn and planted trees, both contributing to grass and ragweed counts.
In Lower Campground, near the bank, hazel and willow lead the seasonal calendar, building through the tail end of winter into March. Grass pollen becomes the dominant allergen through late spring, peaking in June, followed by ragweed's own peak stretch from mid-August into October. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

Does pollen in Lower Campground come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Lower Campground 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 Lower Campground, 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. |
