"So we went from long periods of flow with isolated times of no flow to now it's the reverse where it is long periods without any water at all and small periods of water." Karl Flocke, director of Hays County Parks and Natural Resources, said that to Houston Public Media in a report published in August.
If you live in Wimberley, you may still think of Jacob's Well as the summer swim you'll get back to someday. Four years of data make that a different place now, and the county has set its programs up to match. You walk down to the spring, a guide tells you what you're looking at, and in late fall the trails pick up birds that weren't there in July. Swimming is the rare exception.
The Ratio Flipped in 2022
For most of its recorded history, Jacob's Well simply ran. According to the same Houston Public Media report, the spring stopped flowing for the first time on record in 2000. It stopped again in the droughts of the late 2000s and in 2011, and each time the flow came back with the rain, and swimming came back with it.
Then came 2022. "That's when we dropped down to zero flow and for four years now we've been essentially at zero flow," Flocke told the outlet. Visit Wimberley's listing puts a date on it. Swimming at Jacob's Well hasn't been allowed since June 2022. In a normal year the swim season runs May 1 through September 30 by online reservation.
The current reading tells the same story. The Hays Trinity Groundwater Conservation District tracks the spring through the USGS gage at Jacobs Well Spring near Wimberley. As of October 19, 2026, it showed a 30-day mean flow of 0 cubic feet per second and a 10-day mean of 0. The district's own drought trigger for the spring starts at 6 cfs, and its emergency trigger is 3 cfs. Zero is below every line on that chart. The Jacob's Well Groundwater Management Zone has been in Emergency Stage since March 2024.
July Showed What a "Good" Year Looks Like Now
This summer gave Wimberley a short look at the old Jacob's Well. After heavy rain in July, the flow briefly reached about 22 cfs, Flocke told Houston Public Media. Normal for the spring is roughly 4 to 6 cfs. Water rose out of the hole, filled the pool area and ran down the Cypress Creek bed. Flocke told the outlet that fish had "been trapped in puddles for summers upon summers now."
By early August the flow had fallen well below normal again, and swimming never reopened. The county's reason explains why a wet week isn't enough. Flocke told the outlet that when flow is low, the oils swimmers carry in aren't flushed downstream. They build up in what he called "a direct conduit into our aquifer," home to rare species and possibly endangered ones, including salamanders and beetles.
So swimming depends on sustained flow, and a single good storm doesn't provide it. That puts it out of reach for most of any given year.
The County Priced and Scheduled Swimming as the Exception
The county's Fiscal Year 2027 announcement, posted September 18, sets swim rules for a season that may not come. Swimming is canceled "until further notice due to low water levels." If it returns, it will be sold in two-hour blocks, four a day, with no more than 40 people per block. The price has gone up as well. Swims now cost $12 for adults 13 and older and $9 for children ages 5 to 12, seniors 60 and older, service members and Hays County residents. Children under 5 are still free. The FY2026 rate for the paid categories was $5.
The same announcement keeps general entry free, and the county describes its fees as a way to "manage visitation responsibly." Swimming costs more and has a cap. Walking down to the spring costs nothing and needs no reservation. For a resident, the free visit is now the main one.
What the Walk Down Actually Involves
Jacob's Well Natural Area sits at 1699 Mt. Sharp Road and is open daily from 8 a.m. to 6 p.m., with no entry after 5:30 p.m. You don't need a reservation or payment. The area has about 3 miles of trail. The main trail to the well is about a quarter mile, mostly compacted granite with a stretch of limestone bedrock and two or three staircases.
That last stretch matters if you're bringing someone who can't do stairs. A Travis Audubon event page for the park notes that some trails are crushed granite and considered accessible. It also says the descent to the well itself is not accessible to wheelchairs, strollers or other mobility aids. The page lists [email protected] for accommodation questions.
Weekends add more to do. On Saturdays and Sundays from 10 a.m. to 3 p.m., the Nature Center exhibits, birding station, labyrinth, loose-parts play area and geocaching activities are open to the public. The county's facility page also lists interpretive gardens, a sundial, a pavilion, picnic areas and a playground. With kids, the best visit is a Saturday or Sunday between 10 and 3, when everything is open. On a weekday you get the trail alone.
Late Fall Is When the Trail Gets More Interesting
The spring's habitat goes well beyond the hole in the creek bed. Travis Audubon describes mixed oak-juniper woodland, savanna and prairie, and aquatic and riparian habitat around the well. This time of year, it says, birders may see early arrivals such as kinglets and Hermit Thrush, several sparrow species and overwintering warblers alongside the year-round birds. Those birds come with the season, whatever the spring is doing.
The guided tours are the other reason to go now. Park staff lead a free, roughly one-hour hike down to the spring, covering the history, geology and ecology of the site, how Jacob's Well formed and what's being done to protect it. A dry spring may actually be the better tour stop. With the water down in the hole, you can see what the guide is describing.
Tour dates listed for November and December on the Visit Wimberley calendar, with details on the county's Tours and Events page:
- Saturday, November 7, 10 a.m.
- Saturday, November 21, 10 a.m.
- Saturday, December 19, 10 a.m.
Park in Lot C by the Nature Center Pavilion and arrive by 9:50 a.m. The route covers compacted granite and natural-surface trails with several inclines and some rock ledges, so wear good walking shoes. All three dates fall on Saturdays, so you can stay for the Nature Center when it opens at 10.
Holiday Hours, and a New First Day
Jacob's Well Natural Area closes on Thanksgiving Day, November 26, and Christmas Day, December 25. Plan around those two dates if you have family in town.
The next change comes on New Year's Day. Starting in 2027, every Hays County park except Gay Ruby Dahlstrom Nature Preserve will be open on January 1. County Education Coordinator Katherine Sturdivant said in the same announcement that the parks department is planning a First Day Hike at Karst Canyon Preserve. Sentinel Peak Preserve is expected to open in spring 2027.
Before You Go
Spring conditions here can change quickly, as July showed. Before a visit, check the county's Jacob's Well page for current access. You can also see the latest gage readings on the USGS monitoring page or on the Hays Trinity drought page. Even if the numbers jump after a storm, the county's own description of the July rise suggests the walk and the tour will be the visit for a while.
We live in the Wimberley Valley too, and Jacob's Well is still one of our favorite places to take visiting family, even with the water down in the hole. If you're weighing a property near Cypress Creek and want to know how the creek and the spring behave through the seasons, The Bailey Group can walk you through it.
