Reclamation Information Sharing Environment (RISE)

Reclamation’s Technical Services Center (TSC) Hydraulic Investigations and Laboratory Services Group deployed two Acoustic Doppler Profilers (ADPs) with thermistor strings (for temperature measurement) in Lake Arrowhead between April 2019 and January 2020. This effort provided information on water movement to develop an understanding of reservoir current patterns during mixing events caused by wind, inflows, and pumping station withdrawals. Details on the ADP deployment can be found in Reclamation TSC’s report, which is included as Appendix 2 in the S&T Project 7100 Final Report. The ADP data files can be opened with SonTek ViewADP® Standard v4.03, which is a Windows-based data display and analysis program. It was designed specifically for use with SonTek ADP data. The program can be downloaded at: https://www.sontek.com/software-downloads. An instrument serial number is needed to download the program. The serial number for the mid-lake ADP is C34, and the serial number for the Meadow Bay PC-ADP is H33.
