Delta Water Flow and Use (page 2 of 4)

The maps and graphics below (click
on them to see large versions) were gathered from many
different reports and planning documents published by government agencies,
water contractors, environmental groups, hunting groups, fishing groups,
etc. You will notice that the numbers do not match up. You
will also notice that some reports use gallons to measure water, others
use acre feet, others use cubic feet per second...etc. To understand
the volume of water being shown, you need a conversion chart and a good
calculator. We're providing the conversion chart below. Bottom
line: There is not enough water in California for every person who
wants more water: developers, industry, fish and the environment,
agriculture. Delta land owners, whose families bought their
properties as far back as the 1850's from the Federal and State
governments, have first rights to reasonable use of the water that flows
through the Delta. But more powerful people who do not own Delta
land want to take the water away from Delta land owners, and Delta
environmental needs.
The first two maps below show how maps can be used to
mislead the viewer: Note that the map to the left from 2010
indicates average flow in and out of the Delta from the Sacramento River
was 21,283 TAF but the map to the right from the year 2000 DWR water
summary says Delta inflow from the Sacramento River was 18,327 TAF.
It seems lots of the "historic" numbers revised staring in 2002 or 2003.
Why? We believe for an accurate understanding of ACTUAL flow and use
of Delta water, only documents published before 2005 are "safe" to use,
and 2000 or earlier is probably wiser. |

Maps below: Look closely at the numbers on the
maps, particularly for the Sacramento River and the water pumping plants |
This map from the current draft of the BDCP shows that in water year 2000
Sacramento River flow as 21,283 TAF

This map from a 2005 DWR summary report shows that in water
year 2000 Sacramento River flow was 18,327 FAF, and the chart below this
map says the same. So why did the BDCP change the historic flow
numbers?
