Boat Docks & Piers
Private piers and extended docks reaching real water on a steep, rocky bank — the everyday equipment on this lake, and the work that follows every recovery.
Lakes We Serve · South Texas
Piers, docks and bulkheads on Lake Corpus Christi.
Elevation ninety-four is the line, and the city that draws it is not the city you are standing in. This is also the most volatile water in South Texas — a tenth full in the spring, most of the way back by late summer.
The Permitting Reality
The permitting authority is a city that isn't the local city.
Lake Corpus Christi and Wesley E. Seale Dam are owned and operated by the City of Corpus Christi for municipal water supply. The lake itself lies in Live Oak, San Patricio and Jim Wells Counties.
That mismatch is the thing that catches owners out. There is no river authority here and no Corps lake office running a shoreline program — the controlling rule sits in the Corpus Christi Code's building-code chapter, Chapter 14, in a Boat Docks and Moorings section. And on its face it is a prohibition rather than a permit scheme: it is unlawful for any person, firm or corporation to place, build, construct or maintain any dock, pier, mooring, piling, post, pipe or pole in waters within the city limits or in Lake Corpus Christi Reservoir below elevation ninety-four (94) feet above the reference level specified in the ordinance.
Ninety-four feet is the conservation pool, so everything a marine contractor builds on this lake sits under that prohibition — and the net is wider than most owners expect. A single post, a pipe run, a mooring: the language covers them.
What could not be confirmed from a readable authoritative source is the part everyone actually needs — which City of Corpus Christi department accepts and grants the permission, the application form and fee, the review timeline, whether pre-existing docks are grandfathered, and what standards apply to bulkheads and retaining walls as distinct from docks. The city's ordinance document would not parse. That is not a reason to guess; it is a reason to pick up the phone, and Shoretech verifies the whole process with the city before quoting work here.
Two more layers to plan for. On the land side, expect the county to administer a floodplain development permit — which county depends on the tract, since three of them meet at this lake. And any dredging or fill below the ordinary high water mark draws Corps of Engineers Section 404 review on its own timetable.

Engineering for the Range
Anything built here has to survive being high and dry, and being fully submerged.
TPWD rates fluctuation here as high and frequent, 5 to 10 feet — and the recent record makes the point better than the rating does. Water Data for Texas recorded the lake at 19.4 percent full and 79.37 feet in August 2025, then near a record low the following May, then 86.6 percent full by August 2026.
1
Elevations get set against the range, not the pool
A roughly seventeen-foot rise in three months on a lake whose maximum depth is only sixty feet is not a seasonal wobble. Dock decks, walkway slopes, bulkhead caps and lift heights are dimensioned against the whole travel this water does, because a structure built to one water line spends much of its life either stranded or swamped.
2
Steep rocky banks, and no published bottom figure
TPWD describes steep rocky banks with flooded timber, shallow brushy flats and creek channels, but publishes no explicit bottom-composition figure for this reservoir. Pile conditions get established at the property rather than assumed from a table — and a steep bank pushes the access question to the front of the job.
3
What is under the water is not empty
Submerged trees, humps and old road beds run through the lower reservoir. Vegetation is isolated cattail and rush beds with dense water hyacinth in the upper areas, and clarity runs stained to partly clear. None of that is visible from the bank at full pool.
4
A drawdown is a free inspection
On a lake that has recently sat roughly eighteen feet below its pool, much of what is normally underwater is periodically dry ground — which changes access, changes the elevation a structure has to reach, and exposes exactly what condition existing pilings and footings are in. That assessment happens while it is visible, not after the water returns.
Scope of Work
What Shoretech can build on Lake Corpus Christi.
Pier and dock work dominates over heavy bulkheading here — and the permission question is settled before any of it is priced.
Pier Rebuilds & Piling Replacement
Condition assessment first. When a lake falls to a tenth of capacity, docks and ramps end up on dry ground, and the repair and rebuild work that follows a recovery is substantial.
Bulkheads & Retaining Walls
Bank stabilization and retaining walls for steep ground that takes constant pressure as the pool rises and falls, with the drainage and backfill behind them sized for both states.
Dredging & Ramp Access
Slip, ramp and access dredging with material pumped for reuse rather than trucked off — planned around the Section 404 review it draws.
Know the Water
Three dams on one river bend, and the third one held.
A South Texas water-supply reservoir on the Nueces River, behind a dam 5,980 feet long and 75 feet high at the southeast end.
Two earlier dams stood on this site before the present one. The La Fruta Dam of 1929 breached ten months after it was completed; the Mathis Dam followed in 1935. Wesley E. Seale Dam was completed on April 26, 1958 according to TWDB, and TPWD lists the lake as impounded that year, though some published sources date the lake's creation to 1959. It anchors the southeast end of a long, branching reservoir, with Mathis about four miles to the northeast.
Published surface-area figures do not agree and are worth stating as a range rather than a fact: TWDB gives 18,700 acres at the 94-foot conservation pool, TPWD publishes 18,256, and other sources go higher. No authoritative shoreline-mile figure was found for this lake at all, and maximum depth is about 60 feet. What the numbers do not capture is the character of the place — a genuinely residential shoreline in a hard operating environment, where the drought cycle drives the business more than the buyer pool does.
Around the Lake
Mathis, Sandia, Pernitas Point and the communities between them.
Lakefront homes and lots run right around the reservoir, many with private piers and extended docks, with a state park and several RV-and-marina operations serving the recreation side.

Only community ramps and RV-park marinas were identified around this lake — no large public marina. That shapes the work: single-property piers, dock extensions, piling replacement and bank stabilization rather than commercial marina programs. Shoretech is based in Trinity and travels as far as a project warrants; on this lake the first conversation is always about the city's permission path.
Questions We Hear
Lake Corpus Christi FAQ.
Who permits shoreline work on Lake Corpus Christi?
The City of Corpus Christi — which is not the city you are standing in. The city owns and operates both the reservoir and Wesley E. Seale Dam for municipal water supply, while the lake itself lies in Live Oak, San Patricio and Jim Wells Counties. That mismatch catches people out, and it is the first thing to get straight.
What exactly does the city code prohibit?
The controlling rule sits in the Corpus Christi Code's building-code chapter, Chapter 14, in a Boat Docks and Moorings section — and on its face it is a prohibition rather than a permit scheme. It is unlawful for any person, firm or corporation to place, build, construct or maintain any dock, pier, mooring, piling, post, pipe or pole in waters within the city limits or in Lake Corpus Christi Reservoir below elevation ninety-four feet above the reference level specified in the ordinance. Ninety-four feet is the conservation pool, so in practice everything a marine contractor builds on this lake falls under it.
So how does a project actually get approved?
Honestly: that has to be established with the city, not assumed from a website. Which City of Corpus Christi department accepts and grants the permission, the application, the fee, the review timeline, whether pre-existing docks are grandfathered, and what standards apply to bulkheads and retaining walls as distinct from docks were not confirmable from a readable authoritative source. Shoretech verifies the whole process with the City of Corpus Christi before quoting work here — and any contractor who tells you the answer without checking is guessing.
The lake was nearly empty last year and nearly full now. When should I build?
Both conditions are useful for different work. Low water makes bank, bulkhead and foundation work reachable from dry ground and shows exactly what condition existing pilings are in. A recovered pool makes barge access and pile placement straightforward. What does not change is the design rule: elevations get set against the whole range this lake travels, not against where it sits the week of the site visit.
Will Dave travel to Lake Corpus Christi?
Yes. Shoretech is based in Trinity and travels as far as a project warrants across Texas and western Louisiana. Call 936-662-5100 to talk through the frontage, the permission path with the city, and scheduling.
