High Rock Lake is the northernmost of the Uwharrie Lakes and the second largest lake in North Carolina behind Lake Norman. Its water surface covers 15,180 acres (61 km²) and there are 365 miles (587 km) of shoreline. It begins at the confluence of the Yadkin River and the South Yadkin River. The lake's name is derived from neighboring "High Rock Mountain", the tallest mountain in the Uwharrie Mountains. The lake serves as a boundary between Davidson and Rowan counties and is a reservoir for hydroelectric power generation. High Rock Lake is currently managed and operated by the Alcoa company.

The lake is spanned by two bridges at the northern end of the lake: the I-85/US 52 bridge and the older US 29/US 70/NC 150 bridge. The NC 8 causeway crosses the Abbotts Creek tributary of the lake, as does a bridge at Holloway Church Road farther north of Abbotts Creek. Railroad tracks and their causeways also cross the southeastern portion of the lake at the Hwy 8 causeway and over Flat Swamp Creek. Numerous communities align the lake's banks including Lexington, Salisbury, Southmont, Linwood, High Rock, and Spencer.

[edit] Angling

High Rock Lake has been considered one of the best fishing lakes of North Carolina for a long time ^[2]. It has been the host of Bassmaster Tournaments, including the Bassmasters Classic in 1994, 1995, 1997 and 2007 ^[3] and is the site of frequent other angling competitions. The lake has ample channel, blue, and flathead catfish, plus crappie and several different sunfish such as bluegill, shellcracker and others. Striper and their hybrids as well as white bass are also abundant. The lake is best known for its quantity and quality of largemouth bass, which attract anglers from all over the United States. This is likely due to the relatively shallow nature of the lake and the tremendous amount of habitat that favor the bass.

[edit] Recreation

Most of High Rock Lake is lined with privately owned homes, representing all income levels. Homes that can access 8 foot of water at full pond and have 200 foot of lake frontage are permitted to have a private pier. Boat ramps and boathouses are no longer allowed to be built, although existing structures that are maintained are grandfathered. The new 50 year government contract that is expected to be signed in 2008 would allow greater flexibility to add roof structures over many existing piers and modifying pier sizes, as well as a few other changes that offer somewhat more flexibility to existing lake front home owners.^[4] There are several public ramps to access the lake for free, and private ramps that can be accessed for a small fee. Due to the frequent fluctuations in water level, all private piers are required to be of a floating style, allowing them to be usable even with lowered water levels. The lake has no restrictions on boat motor size or type of vehicle used, so jetskis and other recreational vehicles are legal for use. Because the lake is the first in a chain of lakes, the water stays fairly dark or stained, so swimming is not as popular as other lakes. There are a number of campgrounds that adjoin the lake, some offering year round space rentals.

[edit] The 2002 drought

Record low streamflows caused by unusually dry weather resulted in extremely low water levels at High Rock Lake during the Southeastern United States Drought of 2002^[5]. These dry weather patterns began in 1998 and persisted until 2002. The final year of the drought was the worst for the lake^[6]. With water levels well below "full pond," fish began to die ^[7] due to overcrowding and a lack of water oxygen content, filling the air with rancid smells. Tourism in the area dropped and residents along the lake began to complain. When water levels plummeted to six feet above the "run of river" state (24 feet below normal), federal and state agencies closed the High Rock dam, forcing reservoirs like Badin Lake and Lake Tillery (who were at "Full Pond" status) to pick up the slack to maintain flows on the lower Yadkin/Pee Dee River. This allowed High Rock Lake to return to a "17 feet below normal" level before going down again. In the fall of 2002, the drought eased up and the Yadkin Valley experienced one of the wettest 15 months on record. By the end of 2003, water tables in the area were back to normal levels.

[edit] The 2007/2008 drought

As of March 2008, most of North Carolina is experiencing drought levels that range from Severe to Exceptional (the highest level) ^[8] with rainfall averages below yearly average for the entire state, including the entire Yadkin-Pee Dee watershed. Alcoa is keeping water levels at slightly higher than historical levels for the same time of year for this reason, and possibly because their contract with the US government expires in 2008 and is being renegotiated.

Because the 2002 drought was severe enough to not allow the launching of boats for fishing (or any other purpose), the number of fish that were killed off may have been proportional to the number that would have been caught and kept. The current number of fish in the lake appears to be within norms and unaffected by the 2007 drought. This is further demonstrated by the success of the May 2007 Bass Master's Tournament, and that there are no additional restrictions placed on the lake for fish size, excepting the longstanding restriction for crappie, which have a minimum size restriction of 8 inches. ^[9] Many of the images of fish kills show the primary victim fishes as carp, which are not highly prized in the area and have since made a come back in numbers.

[edit] Drought management

During the 2007 drought, Alcoa has sought and obtained permission from the U.S. Government to reduce the output from High Rock Lake from 1400cfs to 900cfs during the fall, allowing it to maintain higher lake levels. Additionally, they are operating the lake using new guidelines that allow for parity in the lake levels of High Rock and Badin, farther downstream. Previously, Badin had to be maintained at a level no lower than 2 foot below full pond as long as High Rock could provide the water fast enough. New regulations expected to take effect in the new contract due in 2008 would make these temporary measures permanent, reducing the likelihood that High Rock would see lake levels that exceed 20 feet below full pond again. As a result of the new procedures, High Rock has been kept at near record level highs (for the fall season, which is typically -10ft). This has been accomplished although the total inflow of water is less than it was during the 2002 drought, demonstrating that the previous conditions were related to both a lack of rainfall and antiquated lake management rules that were agreed to in the 1958 contract. ^[10]

[edit] Hydroelectric power

High Rock Lake is one of four Yadkin Project dams that produce hydrolelectric power for the surrounding communities. The entire Yadkin Project has a total generating capacity of nearly 215 megawatts of electricity when operating at peak capacity.^[11]. While hydroelectric electricity is clean and renewable, recent droughts and environmental consequences have demonstrated why it is important to balance the need for inexpensive, clean power with the needs of the environment and local communities.

[edit] Relicensing

The hydroelectric dam and control over the lake resources is licensed to Alcoa by FERC (U.S. Federal Energy Regulatory Commission), traditionally by the issuance of 50-year licenses to operate. This license gives the operator the ability to control all water that goes through the dam or over the spillway, within the bounds of the contract and under the guidance of FERC. Additionally, it grants a degree of control over properties that adjoin the lake, including all homes and business that border the lake. All public and private docks, public areas, and even individual home sites are subject to the rules and approval of Alcoa. This license expired in April of 2008 and has been under negotiation for renewal since 2001. This means they will be operating under an annual license until the new contracts are signed and the license is issued.

As of April 2008 ^[12] this licensing process has stalled due to efforts by Stanly County and the City of Salisbury due to disputes about the new license, including Salisbury's demands that Alcoa pay to dredge areas near the city. This multi-million dollar project would seek to restore this section of the lake where the city takes in water. In some areas, sedimentation has grown to over 10 feet deep, and the city, the county (and many private groups and individuals) have claimed that it is due to Alcoa's management of the dam, not allowing the free flow of water during times of maximum inflow, instead only reducing the lake levels during peak demand for electricity would net a greater profit. During the drought of 2007/2008, Alcoa has been operating under the new contract, (under the supervision and with the permission of FERC) although they are not required to do so until (and if) the contract is renewed.
