About
Jeremiah Williamson seeks for his clients durable solutions to water, property, natural resource, and environmental law problems. His experience includes working on the cutting edge of legal issues affecting resource stakeholders today. He founded Williamson Law, PllC, with the aim of sharing his specialized expertise with a broader community of resource interests.
For over a decade, he served as counsel to the United States Department of the Interior and Bureau of Reclamation, providing legal advice and representation on the storage and delivery of water to millions of acres of irrigated agriculture and multiple municipalities, operation of a fleet of hydroelectric facilities, and management of flood risks across the Columbia River Basin. In this capacity, he played a leading role advising on novel applications of the National Environmental Policy Act, Endangered Species Act, Clean Water Act, National Historic Preservation Act, Reclamation law, and state prior appropriation doctrine, among others.
Before joining the Interior Department, Jeremiah worked in the Water & Natural Resources Division of the Wyoming Attorney General's Office. In this role, he represented the State of Wyoming as lead counsel in federal trial and appellate litigation defending Wyoming’s natural resource policies, prosecuting environmental enforcement actions in state trial courts, and representing state agencies in administrative adjudications and before the state legislature.
A product of the rural west, Jeremiah was born in Rock Springs, Wyoming, and spent most of his childhood in Minden, Nevada. When he’s not helping his clients, Jeremiah enjoys spending time outdoors with his wife and two young children. ​
