USACE permit requiredChecked August 28, 2026

Westlake Park at Lewisville Lake

Get a metal-detecting permit from the Lewisville Lake Project Office first. At Westlake Park, detecting is limited to the shoreline band disturbed by waves—not the upland park.

Manager
U.S. Army Corps of Engineers — Lewisville Lake
Start inside
Only use the narrow strip that waves regularly wash inside Westlake Park. Normal dry grass is off limits. USACE defines the band as about eight vertical feet above or below the normal 522-foot lake level.

City permit requiredChecked August 28, 2026

San Antonio city parks

Get a San Antonio metal-detecting permit first. Current city documents conflict on permit length and park scope, so your approved permit and a fresh answer from Parks control.

Manager
City of San Antonio Parks & Recreation
Start inside
A developed park area that Parks & Recreation confirms is covered by your approved permit, away from sports fields, fenced permit areas, natural areas, and archaeological ground.

What this means

The plain-English answer

Texas park rules treat detector use and ground disturbance as separate questions. You need the park’s answer before you switch on, and that answer must also cover how you recover a target.

What is clear

3 rules to carry into the field.

  • The current Texas Parks and Wildlife public rules make unauthorized detector use an offense in state parks, historic sites, and natural areas.
  • Soil, minerals, and cultural resources have their own protection. Detector approval does not automatically mean every target may be dug or kept.
  • A 2026 rule change was proposed to describe superintendent authorization, but no final effective notice was found during this review.

Final local check

Before you leave home

Contact the superintendent for the exact park. Ask whether detector use, target recovery, tools, dates, and areas are all covered by the current authorization.

Federal ground

State rules do not answer federal land.

National Park ServiceProhibited

Federal regulation generally prohibits possessing or using a metal detector in National Park System areas. Narrow stored-device, navigation, scientific, mining, and administrative exceptions do not create a recreational exception.

Bureau of Land ManagementVaries

BLM may allow low-impact prospecting on suitable land, but closures, developed sites, protected areas, cultural-resource law, and active mining claims can change the answer. Ask the local field office first.
