QUESTION:  When did the sub-surface flow barrier across northern head of Steamboat Slough appear, and why?

 

The purpose of this video series showing results of side scan sonar conducted along several Delta waterways in July and August 2015 is to show that the baseline data currently in use for USACE and DWR planning for “reoperation” or revision to the flood and water conveyance systems in California is FALSE or inaccurate baseline data. Video series answers the question regarding Steamboat Slough, along with other affected waterways of the North Delta.   Please view Video #1, which explains the significance of the results of side scan sonar, and then look at the side scan sonar results for the following Delta waterway locations:
Steamboat Slough, by the bridge; Sutter Slough below confluence with Miner’s Slough; Sacramento River by the Delta Cross Channel Gates; Sacramento River below the confluence with Georgiana Slough; Georgiana Slough-3 locations.  Results of these scans show that flow barriers were not accounted for by scientists and computer modelers for the flow and fish migration studies upon which current planning decisions were based.

   USACE public draft of new plan for navigation and flood control, based on the false data developed and published during the “DRMS Phase 1 Report” by DWR/MWD/USFWS   WHY was Steamboat Slough and Sutter Slough flow blocked during the salmon migration studies?...perhaps one reason is to influence the data and reports of CalFed/BDCP, which in turn has been used to validate the decisions of the “WaterFix” and USACE 21st Century water conveyance and flood planning.
