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