The geospatial priority layer used for the Water Resource Protection issue is derived from a layer produced in-house and adapted from the U.S. Forest Service’s Forest-to-Faucet study. This layer prioritizes Texas watersheds by forest importance to surface drinking water for source water protection. Four main factors are considered: (1) watershed importance for surface drinking water, (2) forest importance to surface drinking water, (3) threats to forests, and (4) potential for partnership. The analysis was performed at the 12-digit HUC level. Please refer to the description of the Forest-to-Faucet layer in the appendix on how it was developed. Results from this analysis were compared to the TCEQ assessment “Area of Primary Influence for Surface Drinking Water”.
A Forest-to-Faucets layer was used in Forest Action Plan analyses where Public Drinking Water and Priority Watersheds were used in the 2010 analyses. Its development is described below.
