Decennial flow monitoring project

2009-2011

Decennial flow monitoring meter location mapIn 2009, the Decennial Flow Monitoring (DFM) Project began. A total of 235 flow monitoring units including 223 portable area-velocity flow meters and 12 pump station meters have been installed in the separated portion of WTD’s service area. These meters will be maintained and flow data will be collected over a two wet-season period from September 2009 through early-to-mid 2011. Data from the Decennial Flow Monitoring project will provide the information necessary to check and revise several planning assumptions for conveyance system projects slated for construction over the next 40 years. The final data will also be used for project design and be available to component agencies for their use in planning and design.
