$description="This system flows from the larger town center south of the stream to the stream valley.  Wetland plants help absorb water and purify it.  Plants such as Sagittaria latifolia (Broad-leaf Arrowwood) take up phosphorus and heavy metals, and various Salix (Willows) can be used for water intake.  The riprap checkdam slows the flow and along with retention allow groundwater recharge.  The system functions as an urban park with particular interest during and after rains when ephemerals and wetland plants are most prominent."
