PUBLICATION BY SERIES

HYDROGRAPHIC SURVEY REPORTS (HSR)

There are two general stream adjudications in Arizona, the Gila River System (Gila Adjudication) and the Little Colorado River System (LCR Adjudication).  By statute, ADWR is required to prepare and publish comprehensive Hydrographic Survey Reports (HSRs) for each of the ten watersheds within the two adjudications. HSRs are multi-volume publications that involve intensive data collection and field inspection efforts by ADWR, including detailed information regarding land ownership, hydrology, and the factual basis for each Statement of Claimant (SOC).  The HSRs also include ADWR's recommendations regarding the water rights attributes for each individual water right claim or use investigated.  Click here for more information on the Adjudications Program.
