According to Wikipedia,”Magic Valley” refers to the early twentieth-century construction of Milner and Minidoka Dams and their series of irrigation canal systems on the Snake River, encompassing Blaine, Camas, Cassia, Gooding, Jerome, Lincoln, Minidoka and Twin Falls counties along the Snake River Plain. “In a short time these projects “magically” transformed what had been considered a nearly uninhabitable area into some of the most productive farmland in the northwestern U.S. “ Thanks to the projects, built as a result of Carey Act of 1894, Milner Dam, near the town of Milner, supplies water to over 200,000 acres of farmland, while Minidoka Dam, northwest of Rupert, delivers water to over a million acres.
Building the infrastructure to facilitate this massive undertaking involved countless individuals, organizations and federal funding, built on the surveying lifework of unsung hero Frank Riblett, who conclusively proved the viability of the project from 1879-97. If you’re looking for the magician who waved the magic wand to create Magic Valley, look no further. In his quiet, reserved manner, he must be placed among the giants responsible for developing this bustling, gargantuan agricultural center.
The name, “Frank Riblett,” may not be overly familiar to those who have studied the history of southern Idaho. But, nearly one hundred years after Riblett’s passing on December 24, 1926, his impact on the development of southern Idaho is unmistakable, paving the way to turn previously barren, desolate desertland into the lush, agricultural paradise that has become Magic Valley.
Reportedly shy and somewhat reserved tendencies, Frank’s role in assessing the enormous potential of the Snake River Plain into arable and productive farmland played an integral part in developing southern Idaho’s massive multi-billion dollar ag industry into the global juggernaut it has become. And oh, as a side-note, his services helped save the fledgling Idaho Territory from being dissected and configured into surrounding states including Oregon, Washington and Montana. Idaho as we know it, may not exist without his dedication and collective vision.
Born in Pekin, Illinois, December 24, 1854, the son of Jacob H. and Diana (Fisher) Riblett, at 16, he moved to Iowa, Clark County, Missouri, where his mother died. He then moved to Cheyenne, Wyoming, briefly. Then.traveled by ox team to Soda Springs, Idaho, where he taught in Soda Springs’ first school and also worked for local ranchers. After moving to Dry Creek, southwest of Burley, he then relocated to the Marsh basin, where the town of Albion now stands.
Not quite 22, Frank was Albion’s first paid teacher, in Albion’s first public school, in what was then Owyhee County. He began teaching about 60 students on December 4, 1875. He was paid the lavish sum of $60 for a three-month term, because he had a teaching certificate- a small slip of paper stating he had successfully passed the teacher’s examination. In order to receive his paycheck, Frank traveled to Owyhee County’s county seat in Silver City, a one-way trip of 210 miles. According to Cassia County, Idaho, the Foundation Years, “On one occasion he found that the superintendent had given Riblett’s salary to a merchant to purchase supplies from the East. Riblett had to wait for his money until the merchandise was shipped to Silver City and sold.” He taught school in Albion for 4 ½ years. In 1877 he moved to Oakley, finishing the school-term there, and in 1879 was also known to deliver mail in Oakley, where he lived until 1880.
When the Idaho Territorial Legislature formed Cassia County from Owyhee and Oneida Counties in 1879, Riblett was appointed surveyor of Cassia County. Many of the area’s early settlers pushed for an irrigation system to be built on the Snake River to take advantage of its abundant water supply. “In the beginning, in the years ‘79. ‘80, ‘81,” remembered Riblett, ”some citizens came to me and said there was a possibility of irrigating some lands near the mouth of Goose Creek from a point called the ‘Little Rapids’ in the Snake River. I only had a surveyor’s compass, but I immediately found two men (George Whittle and William Martindale) who were willing to loan me two hundred dollars with which to buy a Gurley surveyor’s transit…and I told these men I was ready.”
In January 1881 he surveyed what became later known as the Minidoka Reclamation project, running several survey lines to verify that the project’s water could be delivered by gravity-fed canals. His painstaking and accurate surveys and reports became trusted resources to justify reclamation projects along the Snake River, as authorized by the Carey Act of 1894. He also identified a second site near Milner. Milner Dam was the first project completed on the Snake River Plain.
In the meantime, Idaho Territory was struggling to survive. Significant settlement had been initiated by widely divergent groups and deep political factions deepened among several groups. Civil War Confederate veterans had moved to the Boise area; miners and prospectors in search of riches thronged to the state, then scattered as claims ran dry, polygamous Mormons from Utah settled southern Idaho further igniting the tenuous political balance. Divisions became so clamorous that Congress openly contemplated dividing the territory among Oregon, Washington and Montana. Idaho’s Territorial Legislature ardently searched for something to unite their beleaguered territory.
After six years of hard and extensive work, Riblett presented the results of his extensive study, proving irrigation in southern Idaho was realistic. His survey was widely read and quoted by Idaho Governor Stevenson and others as an opportunity to unite the various factions, enabling the territory to eventually join the Union. In a speech to the U.S. Congress, Delegate Fred. D. DuBois, reported on Riblett’s surveys and investigations. When the landmark Carey Act was passed, creating the United States Reclamation Service (later the Reclamation Bureau) established in 1902, the foundation for developing the Snake River Valley was laid.
At the age of 44, Riblett responded to the country’s call for troops during the Spanish-American War, joining First Division Eighth Army Corps Company C of the First Idaho Volunteer Infantry. Upon returning to Albion after his discharge in the fall of 1898, he found he had been elected as County Surveyor while serving in Manila.
Frank carried a flag with 45 stars throughout the war, eventually giving it to his friend, Dr. William M. Jones. After proudly being displayed in Dr. Jones’ office for years, his wife, Maud, gave the flag to Berneice S. Bailey in 1973.

Riblett was chairman of the first organization of water users, serving his community in many capacities through the remainder of his years. An expert in water rights law, he was a highly sought-after member of the Idaho State Normal School faculty. He was elected to the legislature, named Water Commissioner and was active in many local political and service capacities, serving for many years as Cassia County Republican Party Chairman.
Frank Riblett’s keen foresight and hard work created the groundwork for massive reclamation projects throughout southern Idaho and the western United States. A small rural community east along Almo’s Narrows area was named after this great and visionary man. Riblett served as a mail stop for many years. The legacy and impact by this great man are truly immeasurable.
