<br /> Project Description/Justification:
<br /> Lake Orange is a Class II (WS-II) public water supply reservoir owned by Orange County. The lake was created
<br /> in 1968 via the construction of an earthen dam and concrete spillway across the east fork of the Eno River. The
<br /> lake's primary uses are public water supply as designated by North Carolina Department of Environmental
<br /> Quality(NCDEQ) and maintenance of minimum (dry weather)flows in the Eno River, as defined within the Eno
<br /> River Water Management Plan (a.k.a. the Eno River Capacity Use Agreement). The Lake Orange dam was
<br /> classified by NCDEQ as a "High Hazard" dam in August 2011 which means that failure of the dam could result in
<br /> severe property damage and/or possible loss of life downstream.
<br /> In Fall 2018, NCDEQ and a private engineering firm conducted dam inspections that identified numerous
<br /> deficiencies, due to the age of this 52-year old structure. This project would represent a multi-year approach
<br /> to repair these deficiencies, by continuing to address high priority needs in FY2020-21. The FY2020-21
<br /> proposal is to repair the existing erosion control barrier and the associated materials testing for a total request
<br /> of$150,000.
