As the largest dam construction project Barnard has completed for the Tennessee Valley Authority (TVA), the project has benefitted from an experienced team. Barnard has worked with TVA on various dam remediation and ash pond closure projects since 2014, and approximately half of the Pickwick staff have worked on previous TVA projects. This experience and client familiarity has proven invaluable, as the project got off to a strong start despite record rainfall and resulting floods. In September 2018, Barnard was level, the tailwater levels at Pickwick the upstream and downstream sides awarded a contract to improve the Landing Dam had risen over 30 feet of the dam.

The reservoir will store approximately 90,000 acre-feet of water and provide 30,000 acre-feet of water annually to the residents of Northern Colorado. As the General Contractor, Barnard will construct a new, 355-foot-tall zoned rockfill dam with hydraulic asphalt concrete (HAC) core, a zoned rockfill saddle dam, a reinforced concrete inlet/outlet structure, concrete-lined tunnel, and concrete spillway. Barnard will also construct water distribution facilities, consisting of large-diameter conveyance piping and construction of a flow-regulating valve house. Preconstruction work began in December 2019; construction is anticipated to start toward the end of 2020 and is expected to last four years. Once completed, the HAC rockfill dam will be the second and largest of its kind in the United States.

  • Natural Resources
    Natural Heritage in the MSNHA The Highland Rim The Muscle Shoals National Heritage Area is located within the Highland Rim section of Alabama. The Highland Rim is the southernmost section of a series low plateaus that are part of the Appalachian Mountains. The Highland Rim is one of Alabama’s five physiographic regions, and is the smallest one, occupying about 7 percent of the state. The Tennessee River The Tennessee River is the largest tributary off the Ohio River. The river has been known by many names throughout its history. For example, it was known as the Cherokee River, because many Cherokee tribes had villages along the riverbank. The modern name of the river is derived from a Cherokee word tanasi, which means “river of the great bend.” The Tennessee River has many dams on it, most of them built in the 20th century by the Tennessee Valley Authority. Due to the creation of these dams, many lakes have formed off the river. One of these is Pickwick Lake, which stretches from Pickwick Landing Dam in Tennessee, to Wilson Dam in the Shoals area. Wilson Lake and Wheeler Lake are also located in the MSNHA. Additionally, Wilson Dam Bear Creek Lakes were created by four TVA constructed dams on Bear Creek and helps manage flood conditions and provides water to residents in North Alabama. Though man-made, these reservoirs have become havens for fish, birds, and plant life and have become an integral part of the natural heritage of North Alabama. The Muscle Shoals region began as port area for riverboats travelling the Tennessee River.

  • TDEC Comments on Pickwick Landing Dam South
    November 9, 2018 Via Electronic Mail to [email protected] Attn: Matthew Higdon, NEPA Compliance Tennessee Valley Authority 400 West Summit Hill Drive, WT 11B Knoxville, Tennessee 37902-1499 Dear Mr. Higdon: The Tennessee Department of Environment and Conservation (TDEC) appreciates the opportunity to provide comments on the Tennessee Valley Authority (TVA) Draft Supplemental Environmental Assessment (SEA) which proposes design changes to the September 2016 Draft EA and Finding of No Significant Impact (FONSI) to document the potential effects of TVA’s upgrades to the south embankment of Pickwick Landing Dam to improve performance of the dam during and following a large earthquake. The Pickwick Landing Dam is a multi-purpose concrete and earthen embankment dam located on the Tennessee River in Hardin County, Tennessee, near Tennessee’s border with Mississippi and Alabama. The newly proposed actions include site access improvements; a new stormwater sediment basin; a new location for a staging area; a new option for use of barges and upstream staging/fleeting areas; and an increase in fill limits. The site access improvements involve the closure of North Carolina Landing Road to public traffic at the intersection with State Highway 128 until the project is complete. Actions considered in detail within the Draft SEA include: • No Action Alternative. Under the No Action Alternative, TVA would take no action to improve the condition of the embankment. TVA would continue to operate the dam and reservoir under normal operations. The risk of a dam breach and reservoir loss during or following a large seismic event would remain. This alternative is not considered reasonable because it does not address the risk to public health and safety or the region’s economy.
