Today's schedule is DCBA

D/C Blocks Social and Environmental Sciences - This morning we're getting in our groups in the library/learning commons for your roundtable research.  The Colorado River basin provides electric power and water to roughly 40 million people - most notably the cities of San Diego, Las Vegas, Phoenix, Los Angeles - and 4 to 5 million acres of farmland in the Southwest. The river water is allotted to states (including tribal lands) and Mexico through laws like the 1922 Colorado River Compact

Should Lake Mead fall to 1,075 feet above sea level, the federal government would cut the water to seven states that depend on the Colorado River, according to an agreement they all signed in 2007. If that happens, the states would likely have to renegotiate the 1922 pact that establishes how the water is to be allocated. 

Water levels in Lake Mead are at their lowest since April 1937, when the reservoir was still being filled for the first time, continuing a 22-year downward trend. Lake Mead was filled to just 27 percent of capacity as of July 18, 2022 (as of October 4th, 2023, the water level is at 1,065.78 feet above sea level which is is 163.22 feet below full pool level of 1,229 feet). As the largest reservoir in the United States, Lake Mead supplies water to millions of people across seven states, tribal lands, and northern Mexico. Additionally, it also currently serves as a stark illustration of climate change and a long-term drought that may be the worst in the U.S. West in 12 centuries. This extremely low water level comes at a time when 74 percent of nine Western states face some level of drought; 35 percent of the area is in extreme or exceptional drought. .

At the end of September 2023, the water elevation at the Hoover Dam was 1065.82 feet above sea level (324.86 meters)…the lowest elevation that the lake can be at while still being able to generate power is 950 ft (290 m). At elevations between 950 and 895 ft (290 and 273 m), the lake can't generate power but it can still release water downstream to the base of the dam. If it drops below that, it won't be able to release water downstream. 

Your assignment is to prepare for a round table discussion about what a renegotiated water compact should include. Instead of states you will be representing "user groups" (agriculture, municipalities, power generation, recreation, environmental organizations, Indigenous governments)

Consider all of the following for the round table discussion...

  1. How much will groups have to share? 
  2. For what purpose should the water be used? Will it be sustainable in the face of growing populations and uncertain climate? 
  3. How can we make our water use sustainable? Are there any conditions that need to be met before different user groups can use the water? 
  4. The original pact for the river was made in 1922. What changes have occurred that would support changes in the pact today? 
  5. Are all the many uses of the Colorado River compatible? If not, what should the priorities be and why? 
  6. Are there fair ways to move water from one use to another? 
  7. Which stakeholders have the power to make these changes?

Remember that the river is a system where all the water is allocated and there is less water available as a whole. Giving more water to any one area or user group means less water available for everyone else. You know your groups. Today research the heck out of it, keep the questions above in mind and come prepared next week to participate in the discussion and come up with solutions. FYI...

Allocation Regime (USBRUC 2005)  

Water quantity: 

Colorado River water was apportioned by the Colorado River Compact of 1922, the Boulder Canyon Project Act of 1928, the Water Treaty of 1944, the Upper Colorado River Basin Compact of 1948, and the United States Supreme Court (Arizona v. California et al. 1963). 

The Colorado River Compact divided the Colorado River Basin between the Upper and Lower Basins at Lees Ferry (just below the confluence of the Paria River), apportioning to each use of 7.5 maf annually. 

In addition to this apportionment, the Lower Basin was given the right to increase its beneficial consumptive use by one maf per year. The compact also contains provisions governing exportation of Colorado River water. The Water Treaty of 1944 obligates the United States to deliver to Mexico 1.5 maf of Colorado River water annually, absent treaty surplus or shortage conditions.  

Upper Colorado use  

The Upper Colorado River Basin Compact of 1948 divided and apportioned the water apportioned to the Upper Colorado River Basin by the Colorado River Compact, allocating to Arizona 50,000 acre-feet annually, with the remaining water allocated to Upper Colorado River Basin States as follows:  

  • Colorado 51.75%  
  • New Mexico 11.25%  
  • Utah 23%  
  • Wyoming 14%  

Lower Colorado use  

States of the Lower Colorado River Basin did not agree to a compact for the apportionment of waters in the Lower Colorado River Basin; in the absence of such a compact Congress, through Secretarial contracts authorized by the Boulder Canyon Project Act, allocated water from the mainstem of the Colorado River below Lees Ferry among California, Nevada, and Arizona, and the Gila River between Arizona and New Mexico. This apportionment was upheld by the Supreme Court, in 1963, in the case of Arizona v. California. As confirmed by the US Supreme Court in 1963, from the mainstem of the Colorado River (i.e., The Lower Basin):  

  • Nevada was apportioned 300,000 acre-feet annually and 4% of surplus water available 
  • Arizona was apportioned 2,800,000 acre-feet annually and 46% of surplus water available; and  
  • California was apportioned 4,400,000 acre-feet annually and 50% of surplus water available.  

Mexico  

The Water Treaty of 1944 obligates the United States to deliver to Mexico 1.5 maf of Colorado River water annually, absent treaty surplus or shortage conditions.

User priority on the Colorado River is determined by the first "useful purposing" of the water. For example, the irrigated agriculture in California has priority over some municipal water supplies for Phoenix, Ariz. You'll look at hydrograph analysis and calculations around volume loss in reservoirs. Before the advent of Bureau of Reclamation dams - Hoover and Glen Canyon - the Colorado River flowed freely to the Gulf of California (Sea of Cortez). In 1920, a stream gage near Yuma, Arizona recorded ~129,000 cubic feet per second (~3,600 cubic meters per second). After Hoover Dam was constructed, flow near Yuma fell below ~ 500 cms. Maximum flow declined further after Glen Canyon Dam came on line, to below ~ 100 cms. The units of this historical hydrograph are cubic meters per second on the y-axis and years on the x-axis. These data show that annual floods on the Colorado River are a pale shadow of the pre-dam period.

Colorado River Supply and Use

From Axios:

The US federal government has formally declared a water shortage at Lake Mead, the nation's largest reservoir by volume, on the Colorado River. The declaration, issued by the Bureau of Reclamation, sets in motion a series of water allocation cuts to downstream states along the Colorado River. The mandatory cuts, referred to as Tier 1 reductions, are part of a contingency plan approved in 2019 after lengthy negotiations among the seven states that use Colorado River water: California, Nevada and Arizona in the lower basin, and New Mexico, Utah, Colorado and Wyoming in the upper basin. American Indian tribes and Mexican officials have also been involved in the planning.

This first round of cuts is going to have the greatest impact on Arizona farmers, as the state will lose 18% of its share from the river, which translates to about 8% of the state's total water use, or 512,000 acre-feet (An acre-foot is about 325,000 gallons, enough water to cover an acre in a foot of water or for two or three households for a year). Farmers in Arizona are likely to experience the brunt of the water cuts and may be faced with tough choices of letting their fields go fallow or tapping dwindling groundwater supplies or other alternate water sources. Under the water allocation cuts, Nevada will lose about 7% of its allocation, or 21,000 acre-feet of water. Mexico will see a reduction of roughly 5%, or 80,000 acre-feet.

Are there Solutions?


And because, you know, it's me...

B Block Human Geography - Today and tomorrow we're in the Learning Commons for us to do an activity looking at the 2022 World Population Data (using both the PRB Interactive Map and the pdf data sheet) to see current trends and numbers in world population. You have a series of questions to answer in your Population and Development workbook and you may work with other people to accomplish this task if you'd like.


For the last question you'll need to choose one of the following demographic variables using the World Population Data Sheet and create a choropleth map showing the distribution of that indicator on a world outline map. The PRB World Population Data map is an example of a Choropleth Map. Use it to help you create yours, just select the indicator you wish to create and it will make a choropleth map that you can recreate.

Infant Mortality
Birth Rate
Death Rate
Total Fertility Rate
Life Expectancy

The instructions are in the Population and Development package but feel free to ask me in class today. Good luck!

A Block Legal Studies - Today we will venture off to the learning commons/library to begin work on our introductory unit major assignment that comes from the Toronto District School Board:

Human rights violations are a daily occurrence throughout the world. These violations take place in both the North and the South and affect the civil, economic, political, cultural, social, and equality rights of human beings. These violations are in direct opposition to the universal and inalienable rights guaranteed by the Universal Declaration of Human Rights (UDHR). Fortunately, organizations around the world work on protecting these rights, partly through education and awareness campaigns

Artists, both visual artists and musicians, often comment on human rights issues through their artwork. Assume the role of the Media Outreach Coordinator for a particular human rights organization (Amnesty International, Human Rights Watch, etc.) and research a contemporary case of human rights violations somewhere in the world. Based on your research, create a Human Rights Campaign Poster that educates the greater public about the human rights violations and urges them to take action to end the abuse.

Remember...
  • Human rights are the basic standards human beings need to live life with freedom and dignity. Human rights include fundamental civil and political rights, such as the right to free speech, to freedom of religion, and the right to participate in government. Human rights also include essential economic, social and cultural rights, such as the right to education, to work, and to healthcare.
  • Human rights are the rights that all people have simply because they are human beings. Each of these rights are inalienable; they cannot be denied or taken away from any individual. They are also indivisible; all human rights are equally important and one right cannot be taken away because it is said to be less important than another.
  • Finally, human rights are interdependent, all human rights are connected and you cannot guarantee one right without ensuring that other rights are protected.
So your task is to...

1. Choose a contemporary case of human rights violations, as well as an organization that is working on ending the abuse.

2. Research your case study using the following websites: Amnesty International (click on campaigns); Human Rights Watch (click on Global Issues); Oneworld (click on In Depth then Human Rights); United for Human RightsYouth For Human Rights or the BBC "I Have a Right to..." site and complete the following questions to help with your poster Case Study:

What is happening? Where is it taking place? What rights are being violated? Who is having their rights violated? Why are their rights being violated?

3. Create a visually appealing Human Rights Campaign Poster that addresses the human rights violation by incorporating the key information from the questions in point 2 above (in point form) as well as pictures, symbols, and colours. Remember, your poster should seek to draw the attention of the public through the balanced combination of text and visuals in a creative, yet educational manner!
