cover of ag water management guide Irrigation and water management information is housed on the Nebraska Extension website Water.unl.edu in the Agricultural Production section. Sub-sections include:

Also see the Agricultural Water Management Guide, a Nebraska Extension publication on irrigation management — both why it is used and more importantly, strategies to improve irrigation efficiency.  Also included are definitions of basic irrigation terminology and a brief history of irrigation. This publication is targeted to farmers, crop consultants, agriculture educators, science instructors, students, and anyone interested in increasing their knowledge of irrigation management.
