WALZEM CREEK GREEN SPACE
In Bexar County, there are 6 watersheds:
​
Atascosa River Watershed
Cibolo Creek Watershed
Leon Creek Watershed
Medina River Watershed
Salado Creek Watershed
Upper San Antonio River Watershed.
The lower portion of the Walzem Creek watershed is characterized by a mix of vegetation and forests and is normally dry except during rain events. Walzem Creek covers approximately 109 km (67.7 miles).
At the beginning of the 1990s...it was characterized by only 64.4% residential areas...and 8.7% and 7.0% of forest and shrublands covers, respectively.
​
(In 2020) most of Walzem Creek is covered with developed areas (84.5%); however, other land uses include wetlands (7.2%), shrublands (4.2%), and forests (2.5%).
This area is a large portion of the Upper San Antonio Watershed; hence, it contributes a large amount of total streamflow.
