Answer:
It
depends on who is counting!
Question:
How much freshwater flows from the Sacramento
River into and out of the Delta, on average? |
| The video links below, and the slides to go with the
video series, focus on how much fresh water flows into the Delta, how
much is exported, and how the answers depend on who's counting.
Links to the documents referenced and many of the water flow maps are
found at the following pages:

The first video looks at how fresh water info to the
Delta has been measured over the years and a possible reason why the
Delta Stewardship Council wants to change how Delta inflow is measured.

The second video looks at how fresh water exports are
"counted" and the question comes up if we should use DWR/USBR conversion
tables or USGS conversion tables as they provide different results. Use

Effect On North Delta
prime farm lands and waterways: Revising how Yolo Bypass Flow is
counted
Click
on the chart to the left (or on the pdf link below) for the data covered
in this video, which shows how specific areas of the North Delta region
may be impacted by the proposed new Delta Plan: Ryer Island, Grand
Island, Sutter Island and the waterways of Sutter Slough, Steamboat
Slough and "Old River" Sacramento between Ida's Island and Georgiana
Slough. Click on this pdf to see the chart-its large, but it may
be helpful when viewing the video.

Summary of the effects is at the bottom of this sketch which was drawn
based on a 1880 cartoon about effects of hydraulic mining and the Delta
waterways. Click on the sketch to see full size:

The video about revising how Yolo Bypass flow is
calculated shows the monitary value gained by the proponents of that
change in calculations. Go to

What is the value of the extra
Sacramento River water exported? Answer: $1.5 Billion per year
to count Yolo Bypass flows differently, and over
$8 Billion per year for the current increase of Sacramento River water
exports. ** uploaded 11/28/2011 |

The third video looks at the reality of net Delta
outflow if the New Delta Plan is approved, and the possible impacts to
the Delta and San Francisco Bay ecosystem. Use this slide set if

The 4th video takes another look at how fresh water
exports are counted and reported, and brings up another question or
conflict between the data that is reported and actual physical
exports...and the value to state water contractors of "mistakes" in
reporting. Use this slide set:
