Located on Cypress Creek just north of Wimberley on Ranch Road 12, this riparian tract includes land above and below the limestone bluffs for which the property was named. The Watershed purchased the land to stop a large condominium development that would have introduced a large amount of impervious cover directly above the creek. It would have resulted in more polluting stormwater runoff in the creek. In its current state, the land and vegetation help slow stormwater allowing it to soak into the ground.
