Weather today, Tomorrow,
The flow providers to this stream are largely stormwater runoff and groundwater. There are no significant tributaries or dams in the immediate vicinity. Seasonal trends show higher flows during the summer due to increased storm activity. One interesting fact about this stream is that it flows through a highly urbanized area, resulting in a higher amount of pollutants in the water compared to more rural streams. However, efforts are being made to improve water quality through stormwater management practices.
