Understanding Proposition 4: Prop Up the Water Fund
I believe access to adequate water will be a pressing issue moving forward in this state
It’s time to continue the breakdown of constitutional amendments with a look at Texas Proposition 4, which will appear on your ballot November 4, 2025. This proposed amendment would dedicate a specific portion of sales tax revenue to the Texas Water Fund, ensuring that water infrastructure gets consistent funding.
Before jumping into it, quick reminder that you can see all the breakdowns here on Substack. I’m going in numerical order, so subscribe and get the scoop as they go live, along with more on local, state, and national politics.
Like the previous ones, let’s first take a look at the ballot language, as provided by the Texas Secretary of State:
"The constitutional amendment to dedicate a portion of the revenue derived from state sales and use taxes to the Texas water fund and to provide for the allocation and use of that revenue."
Once state sales tax collections exceed $46.5 billion in a fiscal year, the first $1 billion of that excess (per year) would go straight into the Water Fund. That money would be reserved for projects like building reservoirs, conserving aquifers, and upgrading pipelines.
The allocation would remain untouchable for the first ten years, meaning the legislature couldn’t claw it back. But after that, they could adjust it by a two-thirds vote.
The directive sunsets in 2047, so it's not permanent permanence, but still locks funding for a solid stretch.
Now let’s look at some hypotheticals:
Scenario 1: The Drought-Prone Farm
Imagine Maria, who runs a family farm in West Texas. After years of unpredictable rains, her well finally goes dry during a brutal drought. Because Prop 4 passed, the Water Fund had already banked billions for projects. The state helps build a new reservoir nearby and implants modern irrigation systems. Maria’s farm survives and, with reliable water, she keeps providing for her rural community.
Scenario 2: The Rapid-Rising Suburb
Now picture a booming Dallas–Fort Worth suburb continuing to expand fast into the next decade. Families rush in, but infrastructure can’t keep up. Natural aquifers are shrinking. Without Prop 4, the local municipal leaders must reallocate general revenue to short-term fixes like restrictive water use rules or expensive surface-water setups that cost homeowners more. With Prop 4, however, dedicated dollars flow in for upgrading pipelines and sustainable water projects, keeping growth manageable and residents flush with water.
But there’s a flip side:
Locked-in revenue can mean loss of flexibility. If there's a sudden need (to fund rural healthcare or rebuild after a disaster for instance) those dedicated billions can't be easily repurposed, at least not without a two-thirds legislative vote.
It’s great for water investment, but what if a major education or health crisis strikes and lawmakers need the revenue elsewhere?
My Take
From my left-leaning, system-critical standpoint stance, Prop 4 can be both a lifeline and a leash. It shows a willingness to invest in long-term infrastructure, which is something sorely needed in a state facing climate stress and growth—I’ve lost track of how many times the power has gone out in my home in Northeast Rowlett this year. But it also raises big questions about who controls those funds and whether dedicating them constitutionally sidelines more pressing social needs down the road.
If your priority is addressing climate and infrastructure proactively (and yes, I believe access to water is a justice issue) Prop 4 reads as practical, not ideological. It’s structured, proactive, and forward-looking.
Would an emergency arise with dire necessity, I would hope a 2/3 majority would vote for it. Though, as we’ve seen with the 2025 Texas Special Session, it’s been more performative bullshit from the Republicans than addressing flood relief for the families impacted by the floods in Kerr county. The Democrats are the ones who called that out.
Alas, I digress.
From these perspectives: I’m leaning yes on Prop 4. I feel access to adequate water will be a pressing issue moving forward in this state and don’t mind locking in a long-term commitment to water while keeping an eye on future fiscal flexibility.
