Can't help feeling so much here in town is wasted, needs to fall West. This here is mostly going to run off right into the lower Colorado.
Arbuckle Reservoir south of Wharton was just built to capture some of that runoff. It will serve the rice growers and replace much of the water that had been contractually required to be released from Lake Travis.
Is it in use yet?
I looked it up. Looks like they're still working on it. There was some groundwater seepage, and they're still working on the barrier wall and testing, etc.
Arbuckle ReservoirLCRA is building the Arbuckle Reservoir, the first significant new water supply reservoir developed in the lower Colorado River basin in decades. LCRA is building the reservoir off the main channel of the Colorado River
The reservoir could add up to 90,000 acre-feet of water to the region’s supply. It is the first project that will allow LCRA to capture and store significant amounts of water downstream of the Highland Lakes.
The new reservoir will benefit the entire basin by helping reduce the amount of water otherwise required to be released from the Highland Lakes to serve downstream demands, including industrial and agricultural customers. Read the fact sheet. Learn about the history of irrigation and agriculture in the Lane City area.
The project has a current life-time budget of $456 million, partially funded by a Texas Water Development Board bond sale and a grant from the TWDB.
Projected in-service date: late 2024.
Project update
During construction, LCRA built an 80-foot-deep subsurface cutoff wall under the berm on the western side of the reservoir to prevent groundwater transference.
In late 2018, LCRA began fill/refill testing after the reservoir embankment was completed. During that testing, LCRA observed groundwater seepage near the site and began a remediation project to extend the barrier wall in June 2019. The barrier wall ranges from about 100 to 175 feet deep. Work on the barrier wall is continuing.https://www.lcra.org/water/water-supply ... new-water/

That was the 10 incher storm that broke the summer 2022 pattern. Similar now just a couple months later.
