Watershed County: Travis
Parameter: Bacteria
River Basin: Colorado River
Segment: 1428C

The Gilleland Creek Implementation Plan includes six management measures and one control action to reduce bacteria. Management measures are voluntary activities, such as restoring and improving riparian buffer zones. Control actions are regulatory activities, such as monitoring E.coli concentrations in WWTF effluent.

Management measures were selected based on feasibility, costs, support, and timing. Implementation tracking provides information that can be used to determine if progress is being made toward meeting goals of the TMDL. Tracking also allows stakeholders to evaluate actions taken, identify those actions which may not be working, and make any changes that may be necessary to get the plan back on target.
