<font face='Calibri' size='4'>The polygon provided in this data layer represents surface designated critical habitat areas based on our best assessment at the time of areas that are within the geographical range of the Austin blind salamander and are considered to contain features essential to the conservation of this species.<span style='mso-spacerun: yes;'> </span>When determining surface critical habitat boundaries, we were not able to delineate specific stream segments on the map due to the small size of the streams. Therefore, we drew a circle with a 262-ft (80-m) radius representing the extent the surface population of the site is estimated to exist upstream and downstream.<span style='mso-spacerun: yes;'> </span>The surface critical habitat includes the spring outlets and outflow up to the ordinary high water line (the average amount of water present in nonflood conditions, as defined in 33 CFR 328.3(e)) and 262 ft (80 m) of upstream and downstream habitat (to the extent that this habitat is ever present), including the dry stream channel during periods of no surface flow. The surface habitat does not include manmade structures (such as buildings, aqueducts, runways, roads, and other paved areas) within this circle.
