Ongoing detention pond maintenance that keeps basins clean, flowing and inspection-ready.
Shallow Hill Country soil over limestone does not absorb much, and on the steep slopes around Canyon Lake that means water moves fast and carries rock, grit and silt straight into the nearest basin. Detention pond maintenance here has to account for that terrain from the start, not treat it as an afterthought once a basin stops draining right.
We see it the same way across Canyon Lake Hills, Mystic Shores and Startzville: a forebay choked with sediment after one hard rain, drawdown that used to take a day now taking three, outlet structures packed with gravel washed off an exposed slope. Embankments left alone for a season or two sprout cedar and mesquite saplings whose roots work into the fill. On lakeside and hillside lots, bare or thinly grassed slopes erode fast, and that soil ends up exactly where you do not want it, in the pond bottom.
For the person responsible for the property, whether that is a board, a management company or a contractor closing out a site, working with Corral Bros means we walk the basin, tell you what the slope and soil have actually done to it, and handle sediment removal, vegetation control, structure clearing and regrading as one scope. We coordinate around an HOA calendar, a leasing office or a construction schedule so the work gets done without turning into a standing problem on your desk.
We're a local, family-built company that treats your Canyon Lake property like our own, tidy crews, clear pricing, and detention pond maintenance that holds up to Comal County conditions. Available as a one-time project or part of an ongoing plan.
Most detention ponds need maintenance at least a few times a year, plus after major storms, mowing and vegetation control regularly, and sediment removal, erosion repair and structure clearing as they build up. Many jurisdictions also require periodic inspections, which we can document.
A neglected detention pond fills with sediment and overgrowth, loses capacity, clogs at the outlet, erodes, and can fail an inspection or stop draining, leading to flooding and code violations. Regular maintenance keeps it functioning and compliant, and it's far cheaper than a rebuild.
We schedule a free on-site visit, usually within 48 hours of your call, and walk the basin with you or your maintenance contact. We look at the forebay, slopes, inlet and outlet structures and note sediment depth and any erosion before putting together a scope and a number, so there are no guesses once work starts.
Most basins in Canyon Lake Hills, Mystic Shores and Startzville need a full service at least once or twice a year, more often if the pond sits below a steep or recently cleared slope. Slow drawdown, standing water past a day or two after rain, or visible silt buildup in the forebay are the signs that tell us it is due sooner.
We stage equipment away from parking and walkways, fence or mark the work area, and schedule around trash pickup, leasing tours or resident traffic when we know about it ahead of time. Most detention pond work happens at the edge of a property, away from building entrances, so disruption to tenants and residents is minimal.
Shallow, rocky soil over limestone sheds water fast instead of soaking it in, so slopes erode quickly and basins silt up faster than they would on flatter, deeper-soil ground. That is also why bare embankments here need regrading and reseeding sooner, and why outlet structures tend to catch more gravel and rock than debris.
Sediment volume in the forebay, how overgrown the slopes and embankment have gotten, and whether erosion has progressed enough to need regrading rather than just cleanup are the biggest factors. Access also matters, a pond tucked behind a steep lakeside lot takes more time to reach than one at the edge of a parking lot.
