Upper Texas Coast fishing maps

Galveston Bay fishing maps and surveyed sections

Upper Galveston Bay is live with quality-assured NOAA depth contours, TPWD Galveston Bay-system fish evidence, 48 measured fishing spots, three forage calendars and official public access. Trinity Bay stays off the public map until its measured depth evidence clears the same fixed release gate.

Why Galveston Bay is split into sections

One bay-wide map would merge distinct upper-bay channels and shoreline structure with Trinity Bay's broad shallow basin. The section pages use exact NOAA named-water polygons and independently pass shoreline, survey, species, forage, access and editorial checks before release.

Source-backed, not crowd-guessed

What is included on every live page

Depth: NOAA BlueTopo survey surfaces, with directly measured, assessed-interpolated and unsupported cells kept distinct.
Fish: five recreational targets documented in TPWD's standardized Galveston Bay-system monitoring and disclosed as regional occurrence.
Spots: source-traceable chart structures and survey-derived transitions retained only where supporting bathymetry is directly measured.
Seasonality: TPWD- and NOAA-backed mullet, shrimp, blue-crab, bay-anchovy and Gulf-menhaden windows presented as search guidance rather than catch predictions.
Access: an exact TPWD Galveston Bay Bay/Beach record; anglers must verify its current condition, hours and facilities.

Not published prematurely

Sections still on survey-quality hold

Held sections remain excluded from search, the public manifest and the sitemap until their exact footprints clear the same no-waiver release standard.

Trinity Bay: Exact NOAA BlueTopo supports only 0.17% directly measured coverage, below the fixed 60% standard gate and 40% compensated gate; no measured-coverage waiver is applied.

Galveston Bay map questions

Frequently asked questions

Why is Galveston Bay divided into separate fishing-map pages?

The broad Galveston Bay system exceeds DepthScout's fixed page-scale threshold. Exact NOAA named-water polygons keep Upper Galveston Bay and Trinity Bay independently testable for shoreline fit, bathymetric coverage, fishing evidence and access.

Which Galveston Bay fishing-map section is available now?

Upper Galveston Bay is live. Its exact 4,787-acre water-only footprint passes at 83.63% directly measured, 99.58% assessed, 0.42% unsupported and 1.25-meter P95 vertical uncertainty. Trinity Bay remains on quality hold because only 0.17% of its exact footprint is directly measured.

Which fish species are supported for Upper Galveston Bay?

Texas Parks and Wildlife Department monitoring supports red drum, spotted seatrout, southern flounder, black drum and sheepshead as Galveston Bay-system occurrence. This is regional survey evidence, not an exact Upper Galveston Bay count, catch rate or daily forecast.

What data supports Upper Galveston Bay fishing spots?

Depth comes from NOAA BlueTopo. Starting areas use authoritative charted shoreline construction, piles, bridges, hard bottom and measured survey transitions, and a recommendation is retained only where the supporting bathymetry is directly measured.

What seasonal forage is documented for Galveston Bay?

TPWD and NOAA sources support conservative search windows for striped-mullet movement and spring or fall shrimp, blue crab, bay anchovy and Gulf menhaden activity. These are regional survey and life-history cues; anglers still need to confirm visible bait, birds, current, weather and sonar.
