Powell sits on irrigated farmland in the Bighorn Basin of northwestern Wyoming, where the dominant vegetation is a mix of irrigated alfalfa fields, sagebrush steppe, and cottonwood windbreaks, shaping the local pollen profile across the seasons. Wind patterns across the area help determine how far pollen travels from these source plants. Nearby towns with similar terrain tend to see a broadly similar pattern.

Does pollen in Powell 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 Powell 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 Powell, 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.
