Reports
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 can be multivolume 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 SOC, and ADWR’s recommendations regarding the water rights attributes for each individual water right claim or use investigated.
For each HSR, ADWR prepares a preliminary and a final draft. Generally, several months and/or up to several years may be required to prepare the preliminary HSR, with additional time allocated to review comments and prepare a final HSR. ADWR must provide notice of the filing of the preliminary HSR to each party and water user within the affected watershed and notice of the final HSR to each party throughout the affected adjudication area. ADWR also prepares and publishes supplements to final HSRs as necessary to update information and provides additional notice to the parties.
