The flow is influenced by rainfall events and human activities, including water withdrawals and dam operations. Significant tributaries include little Brushy Creek and South Brushy Creek. The hydrology of Brushy Creek exhibits seasonal variations, with high flows during spring and fall and low flows during summer and winter. Additionally, the hydrology is influenced by the presence of limestone bedrock that causes rapid infiltration and recharge of groundwater. One interesting fact is that Brushy Creek was once home to a large population of beavers that were actively managed by the city.
