Entry on Private Property
(1)
ORS 536.037 (Functions of director)(1)(e) empowers the director to “enter upon any private property in the performance of the duties of the director, doing no unnecessary injury to the private property.” The director may delegate authority to a watermaster or any other staff member. Authority to enter private property to inspect wells is granted in ORS 537.780 (Powers of Water Resources Commission)(4).(2)
Entry as stated above is restricted to open areas and does not include entry into the house or immediate out buildings except with permission. If an owner or occupant refuses permission to enter or threatens physical harm or obstruction of the watermaster’s performance of duties, the watermaster may seek a court order or an administrative search warrant with the aid of the district attorney or a police officer. If the owner or occupant refuses permission to enter, the watermaster may regulate a diversion that is not on the property if it is accessible.(3)
If a watermaster has reason to believe that water is being used illegally, the watermaster may enter private property to inspect, gather evidence, and/or post any unauthorized uses found, if the watermaster restricts entry to open areas. The watermaster may enter open areas of private property if there exists probably cause that the property contains evidence of a violation of the water laws and urgent circumstances justify warrantless entry. If the owner or occupant is present or has been contacted and refuses permission to enter, the watermaster may seek a search warrant or other court order to enter the property.
