Watershed Facts
- West Bull Creek has a high resource value
and excellent water quality.
- There is a considerable amount of development
going on in this watershed, which has the potential to degrade
the character of the stream.
- West Bull Creek watershed passes through
the environmentally sensitive Edwards Aquifer Recharge Zone
where water travels through caves and sinkholes to “recharge”
the aquifer.
- West Bull is a classic high gradient
Hill Country stream of the Edwards Plateau, with relatively
small and recent development.
