13 Contested Case No. W1-106 14 ARIZONA DEPARTMENT OF WATER 15 RESOURCES’ REQUEST FOR 16 EXTENSION OF TIME

17 Special Master Susan Ward Harris

18 CONTESTED CASE NAME: In re Subflow Technical Report, Watershed 19 HSR INVOLVED: None 20 21 DESCRIPTIVE SUMMARY: The Arizona Department of Water Resources hereby requests an extension of time until April 30, 2023 to file its Subflow Technical Report for 22 the Verde River Watershed.

23 NUMBER OF PAGES: Three and six-page attachment 24 DATE OF FILING: April 2, 2021 25 26

1 In the Order filed November 27, 2017, the Court requested that the Arizona 2 Department of Water Resources (ADWR) develop a technical report and map regarding 3 the subflow zone of the Verde River Watershed. In the Minute Entry Order filed March 3, 4 2020, the Court requested that ADWR file its report by June 1, 2021. ADWR hereby 5 requests an extension of time until April 30, 2023 to file its report. 6 In the course of preparing the report, ADWR found that the geologic mapping for 7 the Verde River Watershed conducted by the Arizona Geological Survey (AZGS) in 2009 8 did not include certain perennial and intermittent tributaries in the Verde Watershed. 9 Attached as Figure 1 and Table 1 are a map and list of the perennial and intermittent 10 stream reaches ADWR has considered for its subflow mapping, including the stream 11 reaches that were not part of the original mapping project. Table 1 reflects ADWR’s 12 recommendations as to whether additional surficial mapping is required for each location 13 or whether additional information is needed for a particular stream reach to allow ADWR 14 to assess the need for additional mapping. 15 Once AZGS completes the work requested by ADWR, ADWR will need additional 16 time to incorporate the new information into the technical report. ADWR hereby requests 17 an extension of time until April 30, 2023 to file its report. This estimated timeline is 18 subject to sufficient funding being available to ADWR. 19 RESPECTFULLY SUBMITTED this 2nd day of April, 2021.
