Tucson Bolsters Water Supplies with LTSC Purchase

The City of Tucson purchased 21,000 AF of long-term storage credits (“LTSC”) from the Bureau of Reclamation (“BOR”). The transaction was part of larger block of 30,000 AF of LTSC that BOR sold last year. The remaining 9,000 AF were purchased by Central Arizona Water Conservation District and Arizona Water Banking Authority.
