Precipitation samples were analyzed for stable isotope delta values between 2003 and 2014 from the Verde River watershed of north-central Arizona. Results indicate a significant decrease in summer isotopic values overtime at 3,100-, 4,100-, 6,100-, 7,100-, and 8,100-feet elevation. The updated local meteoric water line for the area is \u03b42H = 7.11 \u03b418O + 3.40. Equations to predict stable isotopic values based on elevation were updated from previous publications in Blasch and others (2006), Blasch and Bryson (2007), and Bryson and others (2007). New equations were separated for samples from the Camp Verde to Flagstaff transect and the Prescott to Chino Valley transect. For the Camp Verde to Flagstaff transect, the new equations for winter precipitation are \u03b418O = -0.0004z \u2212 8.87 and \u03b42H = -0.0029z \u2212 59.8 (where z represents elevation in feet) and the summer precipitation equations were not statistically significant. For the Prescott to Chino Valley transect, the new equations for summer precipitation are \u03b418O = -0.0005z \u2212 3.22 and \u03b42H = -0.0022z \u2212 27.9; the winter precipitation equations were not statistically significant and, notably, stable isotope values were similar across all elevations. Interpretation of elevation of recharge contributing to surface and groundwaters in the Verde River watershed using the updated equations for the Camp Verde to Flagstaff transect will give lower elevation values compared with interpretations presented in the previous studies. For waters in the Prescott and Chino Valley area, more information is needed to understand local controls on stable isotope values related to elevation.", "description": "Report: iv, 9 p.; Stable Isotope Data", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Tucci, Rachel S.", "givenName": "Rachel S.", "familyName": "Tucci", "affiliation": [{"@type": "Organization", "name": "Arizona Water Science Center", "url": "https://www.usgs.gov/centers/arizona-water-science-center"}]}, {"@type": "Person", "name": "Paretti, Nicholas V. nparetti@usgs.gov", "givenName": "Nicholas V.", "familyName": "Paretti", "email": "nparetti@usgs.gov", "affiliation": [{"@type": "Organization", "name": "Arizona Water Science Center", "url": "https://www.usgs.gov/centers/arizona-water-science-center"}]}, {"@type": "Person", "name": "Beisner, Kimberly R. kbeisner@usgs.gov", "givenName": "Kimberly R.", "familyName": "Beisner", "email": "kbeisner@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-2077-6899", "url": "https://orcid.org/0000-0002-2077-6899"}, "affiliation": [{"@type": "Organization", "name": "New Mexico Water Science Center", "url": "https://www.usgs.gov/centers/new-mexico-water-science-center"}, {"@type": "Organization", "name": "Arizona Water Science Center", "url": "https://www.usgs.gov/centers/arizona-water-science-center"}]}], "funder": [{"@type": "Organization", "name": "Arizona Water Science Center", "url": "https://www.usgs.gov/centers/arizona-water-science-center"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "Arizona", "url": "https://geonames.org/5551752"}, {"@type": "Place", "additionalType": "unknown", "name": "Verde River Watershed"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-112.6, 34.4], [-112.6, 35.3], [-111.3, 35.3], [-111.3, 34.4], [-112.6, 34.4]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 34.849999999999994, "longitude": -111.95}]}]}
