Their full response is here if you're interested. I had to call them to get the projected date.
The two options that are described on the website for raising Scoggins Dam were identified in 2006 when the project was preparing an Environmental Impact Statement. Since that time, concerns about a possible large earthquake off Oregon’s coast and dam safety have arisen. The Bureau of Reclamation has been studying the structure and identifying options for strengthening the dam. Meanwhile, two partners in the project - the City of Hillsboro and Tualatin Valley Water District – are considering other water supply sources (Willamette River). Clean Water Services as the project manager is still considering a possible dam raise, but a much small one about 12 feet which would need to be coordinated with Reclamation’s efforts to reduce the safety risk of the dam.
Not sure how or if it affects the 12 foot water level rise, but around 2009-10 some federally protected species were also discovered in the park, and my understanding is that the presence of those species also decreases the likelihood of the project happening.
