This in turn decreases the incidence of flooding and allows suspended sediments time to settle which reduces pollutants in the storm water discharge.<br><br />Retention ponds typically contain water year round or have permanent pools of water. Examples of these would be Schuman Pond, Ber Juan Lake and Blues Lake. The level of water in a retention pond fluctuates in response to precipitation and runoff or the lack thereof. Periodically these facilities must be drained to allow for removal of sediments that have settled to the bottom of the pond and reduced the storage capacity.<br><br />Detention ponds are typically dry except during periods of heavy rainfall or snowmelt and serve as very important flood control features. A detention pond is designed to hold large amounts of water for short periods of time, such as 24 hours. They reduce peak runoff rates decreasing flood damage and filter storm water pollutants. Examples of detention ponds include Bray Athletic Complex, Forum Cinema detention and Timber Creek detention.<br />Both retention and detention ponds are storm water “Best Management Practices” or BMPs and are very effective if installed properly. The City of Rolla has built 7 detention ponds since 2004 following the passing of Proposition Two. This $3,000,000 bond for citywide flood control removed approximately 200 homes and businesses from the 100 year flood plain and included box culvert and creek channel improvements as well.<br />Rob Hribarhttps://www.blogger.com/profile/07899211857786265688noreply@blogger.comtag:blogger.com,1999:blog-1171377225976787904.post-310759601743704332013-11-16T22:45:27.065-06:002013-11-16T22:45:27.065-06:00Just curious about a relatively unimportant issue....Just curious about a relatively unimportant issue. In several blog entries I have seen the new water facilities identified as "detention facilities." Is that what they are really called, or are they in fact "retention facilities"? As I said, not a terribly important issue, but if it is a mistake, I just hate to see it repeated over and over.Kevinhttps://www.blogger.com/profile/03315992954712466194noreply@blogger.com
