Mesquite, TX – Aug. 14, 2020 – The Palos Verdes Lake dam project to improve the flood control at Palos Verdes Lake has been completed and the lake is ready to be refilled. The forecast showed minimal rainfall for the next few weeks, so McMahon Contracting started refilling the lake by flushing nearby fire hydrants into the storm sewers that discharge into the lake. It is estimated it will take approximately five to seven days to refill Palos Verdes Lake which has a capacity of approximately seven million gallons.
This project was done to replace the rusted metal overflow pipe with a new concrete overflow box structure, modify the emergency spillway and extend the large storm sewer pipe. Learn more about the work completed at www.cityofmesquite.com/PalosVerdesProject.
As a part of the project, the lake’s wildlife and fish were temporarily relocated. The relocation of turtles and fish was completed with the guidance of the Texas Parks and Wildlife Department and with the professional assistance of certified biologists from PondMedics. The Texas Parks and Wildlife Department will restock the lake with fish in mid-October.
Refilling the lake now is necessary to prevent a regrowth of the vegetation that started to grow in the dry lakebed and has recently been removed by the contractor. A total of three fire hydrants will be utilized for the filling process. Total flows from all three hydrants will provide more than one million gallons per day.
Flushing to fill the lake will be gradual to ensure water system pressures are maintained for the surrounding neighborhoods. The potable water that will be used to fill the lake is surplus water that the City purchases from the North Texas Municipal Water District.
