Dam/Spillway Project


The City of Lake Quivira and Olsson Engineering have developed a preliminary design plan for the replacement of the Northwest spillway (downstream side).  The spillway features:


  • Concrete channel that transitions from a height of 10 feet (at the bridge end) to 6 feet (at the spillway end and before the waterfall)
  • Fencing on the top of the spillway for safety purposes that coordinates aesthetically with existing fencing
  • Stonework repair/replacement on both sides of the road
  • Bridge sandblasting and painting
  • Hardscaping (colored/pressed concrete) on the area between the new channel and stone wall.
  • Landscaping on the west side of the spillway up to Renner Road
  • Moving existing power pole on north west corner (discussions in process with Evergy)


Preliminary timeline for the project:


  • Final engineering approval by Council – 7/10/23
  • Submit plans to State – 7/10/23
  • Promote project to potential contractors – 7/11/23
