Note this page shows the results of the early investigation during 2022. Please note the original concept presented to the community so that it appears to be a recreational area.
Please review the open letter regarding the Happy Valley Faults. https://riverroadreservoir.com/wp-content/uploads/2023/01/faults_reservoir-1.pdf
The two drawings below are the rendering of the original concept (bottom drawing), and the current proposed design (top drawing). The primary difference is that the current design calls for a three story high dam surrounding all the water just off Happy Valley Road with most of the water above ground level. The original design called for a larger area under water, but a shallower dam holding the water. The original concept suggested the reservoir would serve some recreational needs. There will be no public access to this 500 million gallons of water surrounded by chain link fences.
The bottom line is that they are planning a three story high dam with a chain link fence surrounding over 500 million gallons of water, most of which will be above ground and above our heads. The plans need to be changed to put that water safely below ground level. And we were not asked.
The technical documents listed below are indeed technical, but don’t let that put you off. It gets easier every time you read them.
[Edit] Note the original “final” proposal in 2016 has been found and it also seems to place the bulk of 500 million gallons of water above ground, though it was intended to be a much lower dam. We have not seen the full plans from the original proposal that was submitted to the Department of Ecology, but you can see the summary of the proposal here.
