Fast ones?? I'm not sure I understand the question.
quote:Canyon doesn't have actual gates. It has a primary outlet works there in the center of the dam along the old river channel that can release water in measured amounts. I'm not sure what type of valve is down there inside the dam that is opened. I'm also unsure if it's fully open with this ~5000 cfs release.
I can't find it Anywhere but do they have all the flood gates open on Canyon?
quote:It's been mentioned before that the reason they are releasing water is to work on the dam. you can see the man lift moving to the right at the end too.
Is that two port o potties in the last few seconds of the video down at the bottom of the dam?
quote:Buchanan isn't specifically designed to hold back Floodwater. It can hold a little bit and can knock the peak off of a flow, but Travis is the only lake in the Highland Lakes that is specifically designed to hold and store floodwater in any significant quantity.quote:It's been mentioned before that the reason they are releasing water is to work on the dam. you can see the man lift moving to the right at the end too.

It looks like LCRA has different targets for "full" on Buchanan depending on time of year.http://www.lcra.org/water/dams-and-lakes/pages/buchanan-dam.aspx
- May-October --> At or below 1,018 ft MSL
- November - April --> At or below 1,020 ft MSL
- 100 YR flood level is 1,021 ft MSL
So right now with teh water level in the lake being about 1,017.## I don't know if the current work that's being done has anything to do with the releases. They just really aren't designed to hold back and store much floodwater. There is some water coming into the lake from upstream so they pretty much have to let it go. I don't know specifically about Buchanan, but I do know for a fact for example on Conroe (same style tainter gates) they can install stop logs and completely dry a gate out to work on it; painting seal maintenance, etc. Working on one gate shouldn't effect overall dam operations.
What does surprise me is that Travis is releasing water even though the downstream river is in flood stage. Travis is "full" at 681.0 ft and is currently at 686.35 ft. I would presume they don't want to store up to the spillway elevation unless they absolutely have to. I guess the details of the dam operation are in their operations manual. That might make some interesting reading!

quote:While they do have targets for "full" at different stages of the year, they are intentionally capping Lake Buchanan at 1018' (2' below max capacity) max year around right now as they perform flood gate maintenance. Not sure when the maintenance is supposed to end. It's been going on for years, but it hasn't really been an issue since the lake has been so low.quote:Buchanan isn't specifically designed to hold back Floodwater.

Lake Buchanan is currently being managed to a maximum storage level of 1,018 feet msl. Under an agreement with the Federal Emergency Management Agency, conservation storage is limited to this elevation in the more flood-prone months of May through October. LCRA is currently limiting storage year-round while upgrades to the floodgates are underway. Read more about the management of Lake Buchanan.
