A pipe has been added to the lake side of the dam.  This pipe will be filled by an overflow siphon (inside the forms shown here).  The pipe at Eldorado will be a 60 inch pipe.

Mallard Lakes Dam work in Progress

This concrete baffle slows the discharged overflow water into the existing creek at Mallard Lakes on the corner of Hardin Road.  A similar but perhaps larger structure would be built on the Eldorado Homeowners Association property and discharge into the creek or the reflection ponds.

This photo shows the relationship of the concrete discharge baffle, the creek, and the top of the dam.

Woodstream and Colonial Drainage Easement

The Association contacted the city of McKinney concerning this drainage easement in the common areas between Woodstream Lane and Colonial Circle.  The City has shaped the drainage easement and placed a seeded erosion preventative covering on the area.

The Fisher-Smoucha Consulting Reserve Study was completed in 1997.  At that time the Eldorado Homeowners’ Association did not own any part of Eldorado Lake or the reflection ponds.  To see this   Reserve Study click here.

At the same time this study was being conducted, the Association asked another company to investigate drainage in the area.  This study was conducted by Baird, Hampton and Brown.  To see this engineering report click here. These estimates were not included in the Reserve Studies.

The most current Reserve Study was completed in 2004 by Criterium Engineering.  It does not include any of the lakes, dams, or bridges which are owned by the Eldorado Homeowners’ Association.  To view this Reserve Study click here.
