Current Approved Aquatic Vegetation Treatment Proposals

Updated March 22, 2019

A Treatment Proposal must be submitted for review to TPWD, as well as local controlling entities, before vegetation management activities are conducted in public water. This page lists current treatment proposals that have been submitted and approved by Texas Parks and Wildlife Department. Note these are only proposals. Depending on weather, plant growth, and available funds, all of the acres proposed for treatment may not be treated.
