A sentence in the Discussion section, first paragraph (page 50) was corrected from: “Numerical models (Scanlon et al. 2001) and water budget studies (Slade et al. 1986) of the Barton Springs segment all consider the boundary between the San Antonio and Barton Springs segments to be a no-flow boundary.” to “Numerical models (Scanlon et al. 2001 and Slade et al. 1985) of the Barton Springs segment considers the boundary between the San Antonio and Barton Springs segments to be a no-flow boundary. Slade et al. (1986) describes intra-aquifer flow between the two segments during the drought of 1955–56 and during a 1978 dry period.” The “Slade et al. 1985” reference was added to the reference list. (2.11.13)
