"It is time for the Department (of Energy) to stop hiding the ball and pretending that the situation at Hanford is being effectively managed," Sen. Ron Wyden, D-Ore., wrote Friday in a letter to Energy Secretary Ernest Moniz.
MATTAWA — Boaters were evacuated over the weekend near Wanapum Dam because of a 65-foot crack in the Wanapum Dam spillway.The district is also lowering water levels by about 20 feet and expects to reach this goal by Monday.
All boat launches at the Wanapum and Priest Rapids reservoirs are closed.
District spokesman Thomas Stredwick said to his knowledge this large of a crack has never been found on a Grant PUD dam. The district is notifying property owners on the Columbia River as part of its emergency action plan.
He said engineers noticed something unusual on the water level while doing routine inspections at the dam earlier in the week. After sending divers into the water, they learned that the crack, which spans the entire length of the dam, had formed about 70 feet under water.
Stredwick said the dam could potentially fail, but that PUD engineers do not foresee that happening.
Where did all the money go?.....well....into a different "crack" entirely. One found on the backsides of the global elite.
Wasn't the stimulus supposed to take care of this?
Where did all that money go again?
Wanapum Dam stabilizing following drawdown Posted on March 4, 2014 by Tom Stredwick Wanapum Dam stabilizing following drawdown BEVERLY, Wash. – Engineering surveys taken on Tues., March 3 at Wanapum Dam show that the cracked area found on one the dam’s spillways is stabilizing. As of yesterday, the crack had closed by nearly an inch, and the damaged section of the spillway monolith moved back upstream by approximately 1 inch. These measurements confirm that the section is becoming more stable as a result of lowering the water level behind the dam. Additional alignment measurements will be taken today. Water levels behind Wanapum Dam are at their lowest today around 543 – 545 feet above sea level. Water levels for the dam at this time of the year are normally around 570 – 571.5 feet. Although reservoir levels are at historic lows and the exposed shoreline is of interest to the public, we remind those that visit the shoreline during this time not to damage or disturb the shoreline area. Recreational vehicle activity along the shoreline is prohibited. We are partnering with law enforcement agencies to enforce state and federal laws, which prohibit removing, altering, digging into or excavating any archeological object or site along the exposed shoreline. Wanapum Dam continues to generate electricity. All boat launches on the Priest Rapids and Wanapum reservoirs are currently unavailable because of the low river elevation. The Wanapum Heritage Center and the day-use park at Wanapum Dam are also closed at this time. The drawdown of the Columbia River is a stabilizing measure taken after divers inspecting the condition of the spillway portion of Wanapum Dam discovered a 2-inch wide horizontal crack across one of the dam’s 65-foot spillways on Feb. 26. A spillway is the portion of the dam that allows water to “spill” past the dam as opposed to running through the turbines. The spillway consists of multiple, independent structural sections that support the spillway gates. Each of Wanapum Dam’s 12 spillway gates are capable of passing roughly 80,000 cubic feet of water per second based on current river conditions. In a worst case scenario, if one of the spillway sections failed, the remainder of the spillways and the main dam structure would remain intact. Under current conditions, the amount of water that would flow through this section of the dam would be within the range of normal river conditions. Grant PUD continues to work in conjunction with the Federal Energy Regulatory Commission as well as upstream dam operators and stakeholders to monitor and evaluate this incident. Public safety and the safe operation of the dam is the utility’s top priority.
