California’s Groundwater Basins

Interested in identifying your California Groundwater Basin? I downloaded California Department of Water Resources groundwater basin .shp file and started a mini project converting it to a .kml that is viewable in Google Earth. After converting it, I colorized each unique basin to make the standout. It’s absolutely amazing how many groundwater basins have been identified in California. […]

UWMP Comment Period Quietly Passes Unnoticed

In a city with nearly 4 million people, there are probably just a few dozen that even know what the Urban Water Management Plan is and even fewer that knew March 16th was the last day to comment on it.  Comments that are submitted during the public comment period are published near the end of the UWMP and for […]

Los Angeles Aqueduct Year End Report

With the Water Year ending last September, this is a look at the Los Angeles Aqueduct supplies from 1975 to 2015. Most of the hard reductions were due to Courts ordering the LADWP to permanently release water back into the Mono and Owens Basins between 1985 and 2007 . The last three years have been due primarily to the State’s drought. […]

LADWP’s Paper Water Leverages on MWD Supplies

When the LADWP uses paper water, not only does it affect Los Angeles residents, it also impacts utilities and residents outside of the city. ‘Paper water’ is water that “utilities claim they have access to, but is difficult or impossible to access for various reasons”.When the LADWP claims to have access to more city owned domestic water than it really has access […]

Thoughts on the LADWP 2015 Draft and UWMP Process in General

If there ever was a reason for the State Department of Water Resources to vet UWMPs that are submitted to it, this should be one of them. For 30 years, the Los Angeles Department of Water and Power’s practice of reporting water that it can’t access has undermined public transparency, making it appear that the city water supply was […]

First Looks: The LADWP 2015 Draft UWMP – Hiding the Shortage

After spending a few weeks paging through the just released LADWP 2015 Draft Urban Water Management Plan, my immediate conclusion is that the plan is a thinly disguised effort to hide the city’s low water supply levels from the planning process to protect development.This draft, like past UWMP’s, continues to project levels of water in all supply categories that […]

LADWP Water Main Blowouts on the Uptick

Recently the LADWP Tweeted from @LADWP that its water main leak rate is less than half of the national average. However, the department’s aging water main ‘blowout’ rate is up 62% from July 2013. Leaks have remained flat during that period. BLOWOUTS   LEAKS    COMBINED    

LADWP 2015 Report Card on UWMP Projections

With the close of the 2015 water year last September, it’s time to step back and take a look at how well the LADWP met its first five year projections that came from the 2010 Urban Water Management Plan. EIR’s winding their way through the planning department use this data to presumably assure us that there will […]

Show Me the Water‘s Failed Promise – The Newport Banning Ranch File

It’s bad enough that water utilities project far more supplies than they have access to which by definition is paper water. It’s bad enough that using this imaginary water they always come to conclusion that every project requesting a WSA has sufficient water to proceed. But recently it became clear to me that are other forms of paper water that comes […]

Drunk History on Solving L.A.’s First Water Crisis

Jack Black gets a lot right about L.A. Aqueduct’s history in 6 minutes on this Comedy Central YouTube video.Maybe they could also put together a Drunk History version behind LADWP’s twisted logic that building 100,000 new units actually saves the city water! Come to think of it, that’s a thoroughly modern day version of China Town.
