Literature Search Item: About 3 yrs ago, the SW NM Stakeholders Group spent a fair amount of money to do a literature search. It amassed many notations in all the fields connected with water. This is still available, so should be used as an additional source for the literature source. Contact the ISC folks in S.Fe for more info.

I am not going to single out any particular item in the narrative portion since I already did so in the Matrix portion. I am going to resubmit a "study method addition" that I did last April during the beginning stages. I will let this "metehnod narration" speak for itself which I consider important. Unfortunately these msg boxes are tricky, it appears one has to make a continuous run as one types in material, I will begin my submission in the next box with title first.

Beginning of Addition to Study Methods>>"Study Method from Gerald Schultz on april 13, 2012 to be Added to Those Already Determined for Scientific Studies on Predetermined AWSA Projects. (Item 1) Do a 3-, 25-, 50, & 100-year frequency detemination on Streamflow for the two CUFA index stations Gila River at Gila, NM and gila River at Clinton, AZ for the following two items: (a) The 7-, 120-, & 180-day low flow averages AND (b) the 1-, 7-, 15-, & 30-day high flow averages. This information can be used as an indicator of how often a person can expect certain flow durations to occur. (Item 2: Do exceedance & duration analysis & graphs on the index stations. Duration curves tell when theer is a significant change in flow and how long it lasts. (Item3): Show at what groundwater pumping rates the Gila and San Francisco Rivers would be significantly affected using an assumed streamflow rate and gradually increased pumping rates. (Item 4): Assume the Gila and San Francisco Rivers are at zero flow and that basin groundwater is the only source. Determine how long before the groundwater levels will show a significant decline from pumping. this assumes that subsurface flow from areas where there is not heavy pumping will be flowing toward those areas of heavy pumping. (Item 5): Show and quantify impacts from a very long prolonged drought. Include rates of surface water declines ate both present and increased pumping rates. There are other aspects of Drought and Climate Change that should be discussed and looked into, but I will not elaborate on it at this time; hopefully it will develop over time. (Item 6): Establish a true surface water/groundwater relationship at the streamflow stations. Establish partial record stations between the streamflow stations to get supporting data. This kind of relationshipss is critical to properly keep tract of both surfacewate & groundwate declines. (Item 7): This item is beyond the scope of what the study contractors will be oing, but there needs to be a region-wide comprehensive ground water assessment similar to the USGS national RASA (Regional Aquifer-System Analysis) studies of the 1970's wher entire basins were studied without regard to political boundries. Such a study would include perinent parts of AZ and even Mexico.
