Carol, the recent flood from the Upper Guadalupe didn’t just bring in logs—it carried serious runoff from rural sources: livestock waste, septic overflow, bacteria, chemicals, and urban debris. These contaminants don’t just float—they settle in coves and along the bottom where families swim and fish. That’s not fear—it’s fact.
We don’t push fake news or promote boating companies. We’re here solely to help the community—especially families—with accurate information, not to make a dollar.
You’ve encouraged boat rentals even in these unsafe conditions. That’s your choice—but it also explains the push to reopen the lake quickly, even before it’s fully safe. We’re choosing safety first.
We want the lake open too—just not at the cost of someone’s health or safety. When it’s clean and safe, we’ll be the first to celebrate alongside everyone else.
