Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.
Detention ponds in Lockhart carry a lot more sediment than their design drawings ever accounted for. Between working acreage south of town and newer development pushing in along the Austin corridor, runoff moves fast across bare and disturbed ground, and it has to go somewhere. For property managers and HOA boards in Historic Square, Clear Fork, and Brock, that usually means a basin that is quietly losing storage capacity year after year.
The blackland clay that makes this county good farmland is hard on a detention pond. It does not drain, it compacts, and once sediment settles into the forebay it packs down into dense muck that will not wash out on its own. We see slow drawdown after storms, standing water that lingers for days, embankments sprouting volunteer trees because nobody has been down there in a while, and outlet structures partially blocked by silt and debris. None of it shows up on a windshield survey, only when someone actually gets into the basin.
Working with Corral Bros on this starts with a free on-site walk, usually within 48 hours, where we check sediment depth and get eyes on the outlet and forebay before quoting anything. From there we excavate and haul the muck offsite, restore the basin to its design grade, and clean out the forebay and outlet so the pond drains the way it was built to. We work on commercial sites across the region and understand that your residents, tenants, or closeout deadline do not pause for construction.
We're a local, family-built company that treats your Lockhart property like our own, tidy crews, clear pricing, and detention pond sediment removal that holds up to Caldwell County conditions. Available as a one-time project or part of an ongoing plan.
We schedule a free on-site visit, usually within 48 hours of your call, and walk the basin with whoever manages the property, whether that is a board member, an association manager, or a GC closing out a site. We check sediment depth at the forebay and main pool, look at the outlet structure, and note any grading issues. You get a clear picture of what the pond needs before any excavation starts.
Most basins on blackland clay in this area need attention every few years, but it depends on upstream land use and how the pond was built. A property surrounded by cleared lots or recent construction will silt in faster than an older, stabilized site in Clear Fork or Brock. The real trigger is performance: slow drawdown after a storm, standing water past a day or two, or visible buildup at the forebay inlet.
Yes, this is routine for us on apartment sites, retail centers, and HOA common areas. We coordinate equipment staging and haul routes to keep drive aisles and parking open as much as possible, and we talk through timing with your property manager or board ahead of mobilization so residents and tenants are not caught off guard. Most jobs do not require closing more than a section of access at a time.
The deep blackland clay around Lockhart holds water and compacts into dense, sticky muck once a basin silts in, which is why forebays here often need more than a light scraping to get back to grade. Heavy spring and fall rain events move a lot of sediment off working acreage and newer development south of Austin, so ponds that looked fine last year can show a buildup now. We check actual depth rather than guessing from the surface.
The main factors are how much sediment has built up, how far the muck has to be hauled offsite, access for equipment, and whether the outlet structure or forebay needs extra cleanout beyond the main pool. A pond with grown-in volunteer trees on the embankment or a partially blocked outlet pipe takes more time than a straightforward excavation. We price it after the site walk, not off a phone estimate.
