Local Environmental Conditions
Around 54% of the area near Washington County Lake Campgrounds is woodland, with some farmland and open water. Close to Washington County Lake, lakeside vegetation adds to local tree pollen. Trees are an important local pollen source, given how much woodland surrounds the area. There is plenty of grass pollen here too.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels. By late fall, as temperatures fall to around 10°C, pollen levels are low again.
