WANAPUM DAM - Grant PUD Commissioners voted March 25 to accelerate plans for scheduled improvements to Wanapum reservoir boat launches during this time of low water conditions, pending regulatory approval.

The Wanapum reservoir has been drawn down by about 26 feet since a fracture was discovered in one of Wanapum Dam's spillway pier monoliths on Feb. 27. Under the low-water conditions, boat launches on the reservoir are all well above the water-line.

"By accelerating the timeline for the improvements, Grant PUD can reduce costs and environmental impacts," Public Information Officer Thomas Stredwick said.

The PUD plans to conduct an abbreviated competitive bidding process for work scheduled for the Kittitas Boat Launch and the Frenchman Coulee Boat Launch. The work includes dredging, shoreline excavations, pre-cast concrete ramp installation, pile driving and slope stabilization.

According to Stredwick, the cost savings for work on the two launches is estimated to be about $425,000. The utility is also looking into the possibility of performing similar work in other locations, pending approval from regulatory agencies.

The investigative drilling at Wanapum Dam continues. It is part of the forensic examination to determine the geometry of the fracture. Fish-ladder modifications are ongoing for a completion date of April 15. A team of experts is also performing an analysis of the cause of the fracture.

"When the analysis is complete and the geometry of the fracture is known, Grant PUD will proceed with a plan to repair the structure," Stredwick said.

Growers are reporting they have made necessary modifications and received permits to water about two-thirds of the 1,200 orchard acres irrigated by the Wanapum reservoir.

Grant PUD continues to work with the remaining irrigators to provide them with needed information as they seek approval from permitting agencies.
