-------------      ------------------------------------------------        --------------------   
Oct. 8, 2008       Various edits, additional USBR Pumping Station         
                   information, and new Flow Diagram figures results in  
                   version 2.1.                                         

August 28, 2008    The Basin Overview Plots were modified.  The green      
                   plots of Daily Consumptive Use are now Daily Net Water
                   Use which is the Daily Consumptive Use minus Rain.

May 1, 2008        New Stream Flow Products figure in the documentation
                   results in version 2.0.1.                          

April 24, 2008     Version 2.0 of the documentation is completed 
                   except for chapter 22.

December 10, 2007  Installed Toni Barrow Farm weather station in           
                   Reach 5.

December 10, 2007  Removed Los Chavez Bosque weather station from          
                   Reach 5.

November 13, 2007  Re-installed Prices Dairy Farm weather station 

October 29, 2007   Removed Prices Dairy Farm weather station from 
                   Reach 4 processing until it is repaired.   

October 23, 2007   Revised the web-site New Mexico home page to allow      
                   more direct access to the Awards and ET Toolbox   
                   products.

October 4, 2007    Added forecast rain for forecast days 4-7.  These       
                   data are Quantitative Precipitation Forecasts from
                   the National Centers for Environmental Prediction
                   Global Forecasting System model.  The resolution of 
                   this forecasted days 4-7 rain is 1 degree by 1 degree
                   (110km north-south by 90km east-west).
                    
June 21, 2007      Modified the New Mexico home page to allow a more       
                   direct link to the MRGCD Stream Flow Schematics.
                   These also remain available from the New Mexico map. 

June 14, 2007      On June 15, 2007, the old AWARDS/ET Toolbox based       
                   on the HRAP 4x4 km grid, 3-day Eta forecast, and 
                   old URGWOM river reach delineations will be shut down.
                   User's will automatically be redirected to the new
                   QPESUMS (abbreviated to QPE) site that is briefly 
                   explained in the May 9, 2007 notes, below.  
                   Documentation of this new site is under way.  

                   In the meantime, information for QPESUMS can be         
                   found at:  http://www.nssl.noaa.gov/projects/qpesums/

                   Information for seven-day weather forecasting by the    
                   National Digital Forecast Database (NDFD) models can be
                   found at:  http://www.weather.gov/ndfd/

June 13, 2007      1. Modified the AWARDS ET charts by replacing the       
                      QPF (Quantitative Precipitation Forecast) values 
                      with 3-day NDFD (National Digital Forecast Data).

                   2. Removed the Candelaria Farms Future 3-days Air       
                      Temperature and Relative Humidity plot since we 
                      no longer acquire hourly forecast data.

May 9, 2007        Numerous changes have been made to the AWARDS/ET        
                   Toolbox.  On May 8, 2007 the following were 
                   implemented:

                    1. Quantitative Precipitation Estimation and Segregation 
                       Using Multiple Sensors (QPESUMS) on an approximate 
                       1-km grid.
                    2. Eight new URGWOM river reaches.
                    3. Seven-day National Digital Forecast Database 
                       (NDFD) weather forecasting models (although the 
                       rain is forecasted for only 3-days, and the solar
                       radiation is approximated from min and max 
                       temperatures with coefficients).  This forecast
                       is on a 5-km grid.   
                    4. URGWOM ET maps for each reach, with 1-week animation.
                    5. Improved ET estimates at 1-km cells that bisect
                       reach boundaries.
                    6. Implemented open water evaporation estimates for
                       the Rio Grande using the FLO2D model.
                    7. Estimating wet sands evaporation within the banks
                       of the Rio Grande. 
                    8. Estimating evaporation from Elephant Butte Reservoir
                    9. Estimating Tamarisk ET in the Bosque Del Apache
                       using the Utah State Univ. model.
                   10. Removed cell rainfall postings.
                   11. Revised design of the Middle Rio Grande web site.
                       
                   The old HRAP 4-km, old reaches, and 3-day Eta 12-km 
                   forecast site is still available until June 15, 2007. 

June, 2006         Rio Chama/Velarde area window created, using an         
                   estimated crop land distribution of 30% orchard,
                   30% alfalfa, and 40% pasture grass. 

April 6, 2006      Generated historic ET summation information for each    
                   of the eight new URGWOM river reaches, based on the
                   HRAP 4-km grid cells, for years 2000-2005.

April, 2006        Implemented a new stream flow schematic for the MRGCD   
                   Belen Division

May, 2005          Implemented Candelaria Farms Firld Scheduling and soil  
                   moisture measurements at many MRGCD weather stations
                   
August 4, 2004     The NMSUCC South Bosque (SBOS) hourly data is now       
                   included in the MRGCD Weather Station Network hourly 
                   pop-up image (fig. 20 in the documentation).
                   This supports the ET Model for Tamarisk - see
                   July 14, 2004. 

July 27, 2004      MRGCD weather stations are added:                       

                                   Name                    Activated

                   The AWARDS/ET Toolbox is rerun each day from 
                   January 1.  Therefore, data from the the NCEP Eta 
                   12 km model is used until the station is active.

July 14, 2004      Added the Model for Daily Evapotranspiration            
                   of Tamarisk at the Bosque Del Apache, as detailed
                   in a paper by Hipps and Hattori, USU.  
                   To see the results of the study, go to the 
                   inter-active AWARDS/ET Toolbox image, and click
                   on the small white square box to the left of
                   the Bosque window.  From there, click on Tamarisk
                   ET Model and Comparisons.

June 29, 2004      Modified nexrad rainfall usage; now based on            
                   vegetative start and terminate dates rather than
                   the entire year.

June 8, 2004       Now Using the newer GIS information for land            
                   classification, a combination of the 2000 IKONOS 
                   satellite imagery at 4 meter resolution and the 
                   2001 Utah State University (USU) aerial photography
                   at .5 meter resolution.  The IKONOS is used from 
                   Cochiti Dam to Elephant Butte Reservoir headwaters 
                   (Reaches 1-7).  The USU exists in a small part of 
                   Reach 3, Reaches 4, 5, and 6, and part of Reach 7.
                   Wherever the USU exists, the IKONOS was erased and 
                   the USU was inserted.  

                   This replaces the 1992/93 Land Use Trend Analysis
                   (LUTA), plus others.  The Toolbox was/is rerun every 
                   day from January 1, 2004 to present with these newer 
                   GIS data for all vegetation groups.

                   The historic runs, from 1975 through 2003, continue to
                   be based on the LUTA, plus others.

June 7, 2004       Implemented the Nambe window.

June 3, 2004       The Daily ET Rate Tables (fig. 18 in the documentation)
                   now contain the GIS classification number. 

May 26, 2004       MRGCD weather stations are added:                       

                                   Name                    Activated

                   The AWARDS/ET Toolbox is rerun each day from
