Yes, collecting sea glass is legal in New Mexico, but only under strict adherence to state and federal land-use laws. Public beaches and shorelines along the Rio Grande and other waterways are subject to the New Mexico State Parks Act and the federal Rivers and Harbors Act, which prohibit unauthorized removal of natural materials. The 2026 update to the New Mexico Environment Department’s Non-Extractive Use Guidelines further clarifies that incidental collection of small quantities for personal use is permitted, provided it does not disrupt ecosystems or violate local ordinances. Commercial harvesting remains prohibited without a permit from the New Mexico Office of the State Engineer.
Key Regulations for Collecting Sea Glass in New Mexico
- State Parks and Public Lands: Collection is banned in New Mexico State Parks under the State Parks Act (NMSA 1978, § 18-1-37), which classifies sea glass as a protected natural resource. Violations may result in fines up to $500 or confiscation of materials.
- Federal Waterways: The Rivers and Harbors Act (33 U.S.C. § 403) applies to the Rio Grande and other navigable waters, requiring permits for any removal of materials, including sea glass, if the action alters the waterway’s flow or composition.
- Private Property and Permits: On non-public lands, landowners may impose restrictions. Commercial collection requires a Non-Metallic Mineral Permit from the New Mexico Energy, Minerals, and Natural Resources Department, with annual reporting obligations.
