2022 Map of Bull Hollow Tank

About this map

The Rio Grande carves a sweeping path through this borderland reach of Webb County, marking the international boundary between the United States of America and Estados Unidos Mexicanos. The landscape is defined by the sharp contrast between the river's winding course and the arid drainage patterns of the high ground, where San Lorenzo Creek cuts toward the water. Human presence is sparse, dominated by the long stretch of Eagle Pass Rd navigating the terrain to the northeast. This 2022 survey captures the region's geographic isolation, showing a terrain largely undisturbed by modern development or dense settlement, where the hydrology of the river basin remains the primary feature of the landscape.
