Delta Water Flow and Use  (page 2 of 4) 1 2 3 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?
