2. A Couple Questions to start off
How many of you have been out of the city?
How many of those who left L.A. have been to the Owens Mouth River?
How many of you have been to Mammoth lake?

3. Los Angeles’s Water Sources

4. The California Drought
The la times reports that California will run out of water in the summer of In response to these numerous scientific reports, the state is currently trying to pass water restriction laws and regulations. However as current charts show and as the forecast persists, the drought will continue.

5. Where water used to come into
Los Angeles
This is the Owens Mouth river used to flow into Los Angeles along with the a series of smaller streams, that eventually hook up with the L.A. River.
Over the past 30 years, L.A. has consumed most of the Owens Mouth River. The Owens Mouth Valley used to be a shallow filled lake or a seasonal flood plains, now it’s now reduced to just a lifeless field of sand.
Over the past 5 years, L.A. is experiencing a lengthy and parched drought.

7. After

8. L.A. Water Sources
The water from Los Angeles comes through a multitude of sources, including several under ground aquifers, and natural springs, plus the Colorado River.
Most of the water is stored in the above-ground reservoirs strung throughout most of the city.
Over the past couple of years, more water is being diverted from the Colorado River to Los Angeles. The City and State of California are hoping to cut back on the amount of water they use in the future.

9. Aliso Canyon Park
Aliso Canyon park is a seasonal creek. However, due to the California drought, the “creek,” has gone mostly completely dry. We did find a source of water and took a sample.

12. The Future of the L.A. River
The city has made an ambitious plan to mitigate the Los Angeles River. The image depicted is of the USC rendition of what they believe the end result of the river is going to look like.
L.A. Works had a fundraiser last week to help clean up the L.A. River.

13. How to water test Materials needed:
Dissolved oxygen and PH Indicators.
10 milliliter tube
1 milliliter tube

14. Results of the Water Tests
Stream Water: 4ppm of dissolved oxygen, 40Jtu, 24 to 26 degrees Celsius, which is an estimated % of dissolved oxygen with in the water. PH of 7
Car Wash Water: 4ppm of dissolved oxygen, 24 degrees Celsius which equals % dissolved oxygen level, 40Jtu, and a PH of 8.
Pool Water: 2ppm of Dissolved Oxygen level, 0Jtu, 28 degrees temperature, PH of 7, % of oxygen level with in the water.
Drinking Water (School): 4ppm of Dissolved oxygen level, 24 degrees Celsius % oxygen level. 0Jtu, Ph of 7.

15. What does the test mean…?
Dissolved Oxygen levels are measured in Parts Per Million or PPM
PH level is measured from very acidic to very basic. Some examples of an acidic PH item, would be lemon juice. An example of a basic PH item would be Baking soda. PH water generally safe for most aquatic animals is between 6-8. A Ph of 7 is “usually the sweet zone”.
Temperature also plays a vital role in the over all health of the water. The higher the oxygen level, the lower the dissolved oxygen level and visa versa for cold water.
