Who excavates stock ponds and dirt tanks in South Texas?
El Venadito RB LLC excavates stock ponds, dirt tanks, charcos, and represas for ranches across Cameron, Hidalgo, and Willacy counties. With our own excavators and dozers we dig and shape the basin, build the bank or berm, and place the excavated soil on the property — and we advise on soil and liner needs before digging. Free on-site estimates: (956) 840-9046.
A Pond That Actually Holds Water
Anyone with a machine can dig a hole. The difference between a hole and a working stock tank is whether it holds water through a South Texas summer. We read the soil and the lay of the land, dig the basin to a depth that survives the dry season, and build up the berm so runoff collects instead of running off — and if the soil will not seal on its own, we tell you what it needs before you spend money on a pond that drains.
What is a dirt tank or charco?
In South Texas ranching, a dirt tank, stock tank, charco, or represa is an excavated or dammed pond that collects and holds water for cattle, wildlife, and irrigation. It is dug into a low spot or built behind an earthen berm so runoff collects and is retained. The terms are used interchangeably across the Valley — a “tank” in Texas means the pond itself, not a metal container.
How deep should a stock pond be in South Texas?
Generally deep enough that it does not dry out in summer or grow over — commonly a minimum of 8 to 12 feet in the deepest part. The right depth depends on the site, the soil, the watershed feeding it, and the livestock it serves. USDA NRCS Conservation Practice Standard 378 (Pond) is the technical reference for pond design, and we can build to an NRCS or engineer's design when one is required.
For many ranch tanks, the goal is simply reliable livestock water, and we shape the pond to your use and site. For ponds tied to cost-share programs or conservation plans, the NRCS 378 standard sets the design criteria your pond must meet — depth, capacity, spillway, and embankment — and we build to that spec.
Will a stock pond hold water in sandy soil?
It depends on the soil. Clay holds water — which is why many South Texas tanks work with no liner. Sandy or loose soil drains and may need a compacted clay liner, bentonite, or a synthetic liner to seal the basin. We look at your soil and where water naturally collects and tell you honestly what it will take to hold water, before any digging starts.
How much does stock pond excavation cost in the Rio Grande Valley?
Cost depends on the size and depth (total cubic yards), the soil, whether a liner is needed, how the spoil is placed or hauled, and access. A small dirt tank costs far less than a large pond with a built-up berm and a liner. We provide free on-site estimates so the price reflects your ranch and your water goal, not a generic figure.
Do I need a permit or to call Texas 811 to dig a stock pond?
Call Texas 811 at least two business days before digging — required under the Texas Underground Facility Damage Prevention and Safety Act (Texas Health & Safety Code Chapter 251), even on private ranch land where buried pipelines and water lines run. A stock pond for normal ranch use on private property usually needs no special permit, but ponds above certain sizes, on or near a watercourse, or that affect drainage may require county, drainage-district, or state water-rights review.
El Venadito RB can advise on whether your pond triggers any of these reviews and coordinates the Texas 811 locate as part of the job. See also our ranch & rural excavation and land clearing services.
