# SUPPLEMENTARY INFORMATION:

In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the Bureau of Reclamation is requesting approval for the collection of data from well and river-pump owners and operators along the lower Colorado River in Arizona, California, and Nevada.

*Title:*                     Lower Colorado River Well Inventory.                

*OMB Control Number:*                     1006-0014.                

*Abstract:*                     Pursuant to the Boulder Canyon Project Act (Pub. L. 70-642, 45 Stat. 1057), all diversions of mainstream Colorado River water must be in accordance with a Colorado River water entitlement. The Consolidated Decree of the United States Supreme Court in                     *Arizona*                     v.                     *California,*                     547 U.S. 150 (2006) requires the Secretary of the Interior to account for all diversions of mainstream Colorado River water along the lower Colorado River, including water drawn from the mainstream by underground pumping. To meet the water entitlement and accounting obligations, an inventory of wells and river pumps is required along the lower Colorado River, and the gathering of specific information concerning these wells.                

*Description of respondents:*                     The respondents will include well and river-pump owners and operators along the lower Colorado River in Arizona, California, and Nevada. Each diverter (including well pumpers) must be identified and their diversion locations and water use determined.                

*Frequency:*                     These data are collected only once for each well or river-pump owner or operator as long as changes in water use, or other changes that would impact contractual or administrative requirements, are not made. A respondent may request that the data for its well or river pump be updated after the initial inventory.                

*Estimated completion time:*                     An average of 20 minutes is required to interview individual well and river-pump owners or operators. Reclamation will use the information collected during these interviews to complete the information collection form.                

*Estimated Total Number of Respondents:*                     1,500.                          ( print page 9265)    

*Estimated Number of Responses per Respondent:*                     1.0.                

*Estimated Total of Annual Responses:*                     1,500.                

*Estimated Total Annual Burden Hours on Respondents:*                     500 hours.
