The Arizona Department of Water Resources’ new Pinal groundwater model is fundamentally flawed when it comes to predicting agricultural use, according to one member of the Pinal AMA Groundwater Users Advisory Council.
GUAC member Scott Riggins made the comment part way through a presentation of the effect of agriculture on groundwater in the model by ADWR hydrologist Jeff Inwood.
Friday was the first time the Pinal Active Management Area council members got an official presentation on ADWR’s new Pinal groundwater model. The model, which ADWR has been working on since 2015, was made public in mid-October.
