1962 106mw Trinity Dam on Trinity River near Lewiston, CA

(Satellite)

"Completed in 1962, Trinity Dam is an earthfill structure that is 538 feet [174m] high with a crest length of 2,450 feet [747m]. The dam forms Trinity Lake, which has a storage capacity of 2,448,000 acre feet....Trinity Powerplant at Trinity Dam has two generators with a total capacity of 105,556 kilowatts"
This dam helps divert water from the Trinity River to the Central Valley Project. So it was built as part of another California water supply project. There is a hatchery that produces about 40m salmonid eggs. (I presume that is per year.) It "compensates for the upstream spawning area rendered inaccessible and unusable by the dams."

Since it has one of the larger reservoirs, I'm surprised I haven't heard of this dam before.

Trinity Dam creates California's third largest reservoir and offers recreation facilities for camping, boating, water skiing, swimming, fishing & hunting. Trinity Reservoir is located in a small basin and primarily fed from snowmelt.

The above stats confuse me because it gives a capacity figure for an auxiliary spillway, but then says there is no auxiliary spillway. The following video implies that there are two spillway outlets.

This video soon pans to the left and shows that we are looking at a second spillway outlet that is downstream from the spillway outlet that is next to the powerhouse.

But I see just the one morning glory spillway entrance, which is on the right side of the dam. So, I don't understand what feeds the second spillway outlet.

Steven Swartz, a member of the Bureau of Reclamation’s Rope Access Team, captured this photo while exiting the Morning Glory Spillway at Trinity Dam in California. The team rappelled into the concrete pipe to conduct a manual inspection as part of the facility’s routine maintenance schedule.

Robert Stuart: Reminds me of when I inspected the cavitation damage in the Trinity Dam outlet works.

Brian Jules posted eight photos with the comment: "Rocky River Ohio with the 1925 Hillard rd concrete open arch spandrel bridge across the valley. The bridge has been dutifully spanning the Rocky River valley for one hundred years. The bridge had a major renovation from 1980-1983 with the deck replaced as well. Sadly continued  high maintenance and rebuild cost has forced this bridge to be replaced in the near future."
