WORK BEGINS ON DETENTION POND – Construction began Nov. 20 on the $81,592.50 detention pond on the creek that runs behind the El Dorado Springs R-II School softball, baseball and football fields. The contract calls for Bennett Construction Company, Lamar, to complete the job in 90 days, but the foreman said Monday that “barring weather complications, there will be a lot of changes in a month.” The Olsson Engineering firm said that in the event of a big rain, the detention pond should reduce the flood surge that hits downtown El Dorado Springs by about half. Downtown was flooded twice in recent years by downpours billed as 100-year floods.

On Monday, after using a track loader to stack sawlogs, the crew started digging a pit in which to burn the brush pile. They will use a special fan brought in from Tulsa, OK, to accelerate the blaze and reduce smoke to neighbors which include residents of the mobile home park (seen in background) on East Fields Blvd to the north of the pond. On Tuesday, the main drainpipe was delivered. The crew will dig down to solid rock, then place the 24-inch pipe at the bottom of the earth dam it will build. The pipe is sized to drain the detention pond in about 24 hours, depending on the amount of rain received, if the basin is completely full and the rain stops. The design calls for the stream flow to remain normal at all times. City Manager Bruce Rogers said that at full pool the water should back up to a spot between first base and home plate on the baseball field, just several feet down over the hill.
