Title

Brooktrails Rubber Spillway Dam Project

Description

The purpose of the proposed project is to restore the storage capacity lost (52 acre-feet) due to siltation at Lake Emily. Brooktrails proposed project would replace the existing wooden flashboards by installing inflatable gates, thereby increasing the maximum water level in Lake Emily by three feet. The spillway gate will be 48 feet wide and the structure will include a base slab, 15 foot high concrete cutoff walls, and airbladders to operate the steel gate panels. Installation would be done when the lake water level is eight feet below the spillway. The proposal includes the installation of berm at the dam toe and construction of a small dam control building. The dam would be reinforced at its southwest corner with the addition of an earthen berm to support the foundation and to increase the dam integrity. The berm will have a 225 foot long blanket drain that varies in elevation. Compacted earth and fill material from a borrow area adjacent to the dam will be used in constructing the berm. The earthen berm will fill in 0.04 acre of wetland located at the base of the dam. A 10 foot by 15 foot control building will be constructed near the spillway and may contain an office area.
