Revisiting Holway Reservoir

On the Saline Creek Arm of Lake Hudson, the Grand River Dam Authority’s W.R. Holway Reservoir (pictured), plays a unique role in power production while also serving as a favorite year-round destination for anglers.

Located in the hills southeast of Salina, Oklahoma, the Grand River Dam Authority’s W.R. Holway Reservoir is a bit off the beaten path. Resting high above the Grand River valley, in a place where the river never flowed, the reservoir does not always garner the attention that it’s “sister lakes” – Grand and Hudson – get from water enthusiasts. In fact, many consider Holway Reservoir one of the best kept secrets in the state.

However, while its 712 surface acres of water and 21 miles of shoreline may pale in comparison to GRDA’s other lakes, the role that this particular reservoir has played in GRDA’s overall operations is an important one.

The reservoir was created in 1968 when GRDA completed a 200-foot earth and rock dam in Chimney Rock Hollow, as part of the construction of the Salina Pumped Storage Project (SPSP). Using hydroelectric pump-turbines in the SPSP powerhouse, GRDA can fill the reservoir with water from the Saline Creek arm of Lake Hudson. The water is pumped from the creek, through the powerhouse, 250 feet up the side of a bluff, and into the reservoir above. In time when the water is needed for generation, it is released from the reservoir and flows back downhill, through the pumps, now serving as generators. Essentially, Holway’s waters serve as a battery for GRDA electric generation.

Open to the public and always a favorite of anglers, Holway is a favorite destination year-round. Although GRDA rules prohibit the use of internal combustion engines and swimming, visitors can be found using canoes, paddles and electric trolling motors to navigate the deep, quiet and clear waters.

As is the case with all its hydroelectric facilities, GRDA reminds visitors to Holway Reservoir to be aware of the notifications around the facility. Signs, buoys, sirens, fencing and flashing lights are all intended to notify those in the area when floodgates are open, generators are operating or water is rising swiftly. Educating yourself on this signage and the reservoir area can help insure a fun, safe visit to one of Oklahoma’s best kept secrets.

GRDA is Oklahoma’s largest public power electric utility; fully funded by revenues from electric and water sales, instead of taxes.
