Northern Water’s Weather Station Network Mark Crookston June Caves Tim Lynch Mary Hattendorf

Weather Station Network Provides weather & crop water use information throughout service area 21 automated stations – 19 on eastern plains, 2 on west slope at high elev Solar powered CDMA modems: presently downloaded hourly, moving to more frequent Station sites carefully selected –in alfalfa fields or large turf areas Air temperature, relative humidity, rain/precipitation, wind speed/direction, solar radiation & soil temperature Every sensor serviced & calibrated at least annually

Northern Colorado Water Conservancy District Weather Station Network Provides crop water use information for northeastern Colorado

ET Reference ASCE Standardized Penman-Monteith equation Hourly calculations: ETrs for alfalfa & ETos for turf grass Daily (available now), weekly, monthly, quarterly, and yearly data aggregations available via web (soon). ETrs is factored using coefficients based on crop growth stages for all major crops grown in the area

Turf Water Use Reports 2012-enhanced report Range of DU & precipitation rates Supply suggested sprinkler run-times Goal is to provide better guidance and education urban lawn irrigation Interactive run-time scheduler pending this year? Next year?

Northern Water Weather Station Network In May 2010, the Boulder Flatirons and Boulder East weather station were dropped from the network Stations owned by City of Boulder Instruments and Campbell logger were obsolete Station sites compromised

Boulder East Prairie dogs No irrigation No green fetch

Boulder Flatiron Distance from tall trees inadequate Tree casting a shadow over the station
