Pond Excavation in Bridge City, TX

Pond Excavation Services in Bridge City, TX

Ponds on this ground come with two questions that inland ponds do not have: how close the water table is, and whether what fills the pond will be fresh. We dig ponds across Bridge City and the surrounding parts of Orange County. Free on-site estimate.

The clay here holds water perfectly well, so leakage is rarely the problem. The problems are different. The first is the water table. On low ground it sits close to the surface, which sounds like an advantage for a pond and is a mixed one. It means an excavation finds water quickly, which is convenient, but it also means the pond level is tied to the water table rather than being controlled by what you built. A pond that is essentially a window into the water table behaves differently to one filled by surface catchment. The second is salt. Surge has pushed saltwater across this ground more than once, and on the lower parts near the marsh there is a genuine question about whether groundwater is fresh. A pond intended for stock or for fishing that turns out to be brackish is a serious disappointment and it is not something that can be fixed afterward. The third is that a pond on ground this low interacts with flooding. During an event the pond and its surroundings are simply under water together, and what matters afterward is whether the dam and spillway survived and whether anything undesirable was deposited. Around sixty inches of rain a year on this stretch of the Gulf Coast, and repeated flooding from Rita, Harvey and Imelda, set the context.

We test before digging on this ground, and here that means checking the water table depth and, where there is any reason for concern, the salinity of what is in it. That testing is cheap relative to the excavation and it answers the question that decides whether the pond does what you want. A pond for irrigation, for stock or for fish has a salinity requirement. A pond dug for aesthetics or for fill does not. Siting follows from that. Moving a pond to a location further from the marsh edge or to slightly higher ground can change the answer, and it is free to move before excavation. Depth still matters for the same reasons it does anywhere: shallow water in this climate warms through, goes green and drops in a dry spell. Where the pond is tied to the water table, depth also determines how much buffer there is when that table falls. The spillway gets designed properly. On low ground the consequence of a failure is less dramatic than on a slope, but a breached dam still means a lost pond and a repair bill several times what an adequate spillway costs. Spoil is real volume and on this ground there is nearly always a use for it, since a great many properties here need fill for elevation. That turns disposal into a second job. Where trees have to come out, Orange County burn bans and TCEQ outdoor burning rules govern the material.
