This layer contains the data for the storm sewer detention ponds in the City of Round Rock, located in Williamson County, Texas. This layer is part of an original dataset provided and maintained by the City of Round Rock GIS/IT Department. The data in this layer are represented as polygons.<\/SPAN><\/P>

<\/P>

A storm sewer detention pond, or retarding basin is an excavated area installed on, or adjacent to, tributaries of rivers, streams, lakes or bays to protect against flooding and, in some cases, downstream erosion by storing water for a limited period of time. <\/SPAN><\/P>
