Leaky Dam to Go Geosynthetic?

The Canyon Creek Meadows Dam in Oregon is leaking. It’s reservoir, which is now only filled with seasonal precipitation, has been prone to leaks since the 1960s when it was constructed. Locals would like to save the structure, but to do so will require improving the reservoir. Failure to do so will lead to either decommissioning the hydraulic structure or structural failure. Repair strategies being debated include lining the reservoir or even creating a double liner system of geosynthetics and compacted clay.
