Aquatic Vegetation Treatment Proposals

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 the treatment proposals that have been submitted to Texas Parks and Wildlife and approved in 2009-2011. Note these are only proposals. Depending on weather, plant growth, and available funds, all of the acres proposed for treatment may not be treated.
