1 Use of Water in New Mexico analyzed by county Name: Matias Mario Mendez Larrain Course: CE 547 Professor: Julia Coonrod April 29 th 2013

2 Introduction Water consumption is defined as water withdrawn that is not directly returned to its original source. Under this definition, all ground water withdrawals are consumptive unless the water is returned to the aquifer from which it was obtained. Surface water withdrawals are considered consumptive if the water is not directly returned to the source so that it is available for immediate further use. The purpose of this report is to provide decision makers with the most comprehensive, current and useful water use data available so that informed decisions can be made to insure the conservation and wise use of the state's water resources. The project estimates the water withdrawals for the categories of public supply, selfsupplied domestic, industrial, irrigation, and thermoelectric power at the county. Estimates too the water withdrawals for aquaculture, livestock, and mining are prepared for each county. Estimates of deliveries of water from public supplies for domestic use by county also will be prepared. Fresh ground-water and surface water estimates will be prepared for all categories of use; and saline ground-water and surface-water estimates by county will be prepared for the categories of public supply, industrial, and thermoelectric power. Power production for thermoelectric power will be compiled. The data source comes from USGS. Objectives - Analyze the use, and disposition of water resources by county. - Analyze the basins in New Mexico and the coverage of them. - Analyze the diversity of categories and the importance of each by county. - Determine the percentage served by county. - Analyze the power generated by county. - Analyze the irrigation and the impact of it. - Determine the percentage by county of water use. - Find the critical counties in New Mexico Using GIS The coordinate system used in the project is GCS_North_American_1983, I decide to use this coordinate system because it is standard and a perfect view of New Mexico in this project is not vital. The counties were extracted from the RGIS data from the University of New Mexico DATA BASES.

3 The main table I used for this project was extracted from the USGS data sources according the water consumption by county. The table is annexed and the data corresponds to I also used a view of the rivers because was important to define where the power generation sources come from. In one layout I will show how the rivers can represent a source for powering in the different counties. The tools I most used in this project were the properties layouts, symbology, the table properties to define the values for new fields and the joining and relating tools. Results The results I found in this project are layouts that will show the different analysis I made and how we can represent them. The basins that cover the counties in New Mexico are the following:

4 Layout 1 In this layout I want to show how the consumption of water in New Mexico is distributed and how is the difference. From this layout we can analyze that. San Juan and Dona Ana are the counties who more water consume in the state, Socorro and Roosevelt are counties who have less people and their consume is in the third level. We can also analyze that Santa Fe and Sandoval are counties that have a considerable amount of people but they are in the second level of consumption.

5 Layout 2 This layout shows the predominance of each category by county. It is clear that irrigation is leads the table in most of the counties. There are only 3 counties who have mor public supply than irrigation, those counties are Bernalillo, McKinley and Los Alamos with a fully public supply county. The other categories are composed of: - Irrigation - Public Supply - Aquaculture - Mining - Industrial - Livestock - Thermoelectric - Domestic

6 Layout 3 This layout show the percentage served by water in the different counties. We can observe that more than the 50 percent of the counties in New Mexico are not above the range of 80 percent. I used the 80 percent since is the percentage served for all New Mexico. The parameters I used were the total population by the state and counties, and the amount of people who gets served. Torrance, Los Alamos, Mora and Valencia are the critical counties.

7 Layout 4 This layout shows the amount of power generated in the thermo electrics. We can see that there is only one county who make difference and is San Juan, not to mention that is the state who more water consumes in the state. Lea and McKinley have a considerable amount of power generated but not as much as San Juan.

8 Layout 5 This layout shows the amount of acres irrigated and the percentage of the county area that is irrigated. I create this layout with to have an idea of how can be the impact in the economy for New Mexico of each county. Since there are counties who uses to much water they also contribute to the economy.

9 Layout 6 This layout reflects the distribution of the withdrawals. We can observe that the amount of water taking from the surface and from the ground is almost the same. If we observe the rivers direction from another map it pass near from the counties where they get surface water.

10 Layout 7 The final layout shows the percentage of water that each county use in all New Mexico. The other map also shows the counties who more contribute to economy in terms of energy, irrigation, water supply and amount of population. San Juan, Dona Ana and Bernalillo are the counties who more contributes. Valencia, De Baca and Luna are the counties who less contributes.

11 Conclusions and Recommendations - The counties who more contribute at the state of New Mexico in terms of water coverage, energy production, amount of acres irrigated, amount of people and water consumption are Bernalillo, San Juan and Dona Ana. The counties of De Baca, Lunas and Valencia are the counties who less contribute New Mexico. - New Mexico water supply is covered by surface water and groundwater almost at the same rate in terms in percentage. - I would recommend collect wastewater data to have a point of view of New Mexico in terms of sustainable resources. - Determine the sources of the withdrawals would give us a better view of which county takes more risk in New Mexico in terms of Sustainable Water. - GIS is a powerful tool to handle data and process it.
