Streamflow can be variable in the city. During dry times, groundwater provides much of the base flow to local streams through springs and seeps. Streams can rise rapidly in response to storm events.
As watersheds develop, less water makes it into the ground because of an increase in imperviousness. Water flows across impervious surfaces into a stream instead of flowing or sinking into streams over longer periods of time. Stormwater Control Measures (SCM) like bioretention and rain gardens promote infiltration of this water. Infiltration captures pollutants and allows the land to manage water as it did prior to development.
Streams with the most baseflow:
