Newdale is a city in Fremont County, Idaho, United States. The population was 337 at the 2020 census. It is part of the Rexburg, Idaho Micropolitan Statistical Area.

In the early 1900s, there were only a few homes and farms scattered across the vast terrain east of Teton City. Early settlers in this area include family names such as Siddoway, Briggs, and Schwendiman. The Schwendiman family, consisting of 6 brothers and their mother, a widow, relocated from Paris Idaho to Teton Idaho in 1894. As the Schwendiman brothers grew older and married, they began to homestead and dry farm in the area east of Newdale, and obtained land in 160 acre parcels via the Homestead Acts. Part of this land includes where the City of Newdale now sits. Many families in this area would live on their farms, working from spring to fall, but would move to Teton or other nearby towns during the winter months.

In 1912, a one-room rock school house was built in Bowerman, an area 2 miles east of present-day Newdale, to accommodate approximately 15 school children living in the surrounding area. The school house was also used for LDS Church meetings. Bowerman may have developed into a village, if had not been for the railroad being built in the Newdale area, which encouraged growth.

The Oregon Short Line Railroad wanted to expand into this part of the country and on June 27, 1914, purchased a right of way from brothers Sam and Fred Schwendiman to lay tracks for a new branch line. The new railroad attracted people to Newdale and in 1914 the Edwin Moroni Stocks family built a house and the Leo Schofield family built a cabin. Mrs. Hansine C. Hansen, a widow, was also one of the first people to move in, and had her sons move her house from Teton, perhaps early in 1915. Burt Garner was also one of the first to build a home and move in, and he also started a grocery store.

Sam and Fred Schwendiman incorporated the Newdale Investment Company for commercial purposes, which erected a rock building that housed, on the ground floor, a hardware supply and drug store. The other part of the building was leased to the First National Bank of Newdale, an independent bank managed by G.C. Alden. Upstairs, a fine recreation hall was completed for dancing, with a stage where operettas and drama productions could be given. The facility formally opened in June 1915 and attracted considerable attention at the time. A train depot was also built in 1915, and catered to both freight and passenger service. Later that summer, in August, a group of men representing the Chamber of Commerce came to Newdale by train and were entertained at this community center before making the loop back to Idaho Falls.

The US Post Office established a Newdale Post Office and on February 15, 1916, appointed Sam Schwendiman as the first post master.

On March 17, 1916, the water system was completed, including a wooden elevated water storage tank and underground wooded water mains. The project cost $15,000 (some records say $18,000).

The Newdale Investment Company made land available for the townsite of Newdale, which was surveyed and plotted by engineers Cotton and Wilson in April 1916. In May, several hundred shade trees, apple trees, and other fruit trees were planted throughout the town. The LDS Newdale Ward was organized on December 17, 1916, with Lester Hanson as the first bishop. School and church meetings were held in a vacant building on Main Street. In 1916, a contract was negotiated with the Utah Power and Light Company, to bring electricity to Newdale. Telephone service came shortly after. The Idaho Falls Daily Post published a notice with headlines that read: "Newdale bright lights beckon to the world. All over the Upper Snake Valley the question has been asked, 'What are these many electric lights we see twinkling up on the bench every night?'"

The Village of Newdale was incorporated in January 1917. The first town board was: Joseph Fleischman as chairman, Frank Williams as clerk, Burt L. Garner as treasurer, and Edwin Stocks, George Bean, Henry Campeau as board members. In the fall of 1915 an incorporated Company, known as the Farmer's Warehouse Company, built a large warehouse in Newdale, which became the shipping point for crops raised in the surrounding area. Sugar beets were the main crop of the area, followed by grains, alfalfa, and seed peas. Potatoes would become the main crop after 1920.

In 1918, the Spanish Influenza hit, and the whole town masked their faces when going out in public. School was let out for the year because of the flu.

The year 1918 produced one of the best crops that has even been produced in this area. Newdale grew rapidly and by 1919, after being only four years old, it had a national bank, a mercantile and drug store, a barber shop, a blacksmith, a carpenter shop, a printing shop, a real estate office, a livery stable, several general stores, lumber yards, hardware stores, implement yards, warehouses, grain elevators, commission houses, hotels, restaurants, and an opera house. It is estimated that Newdale doubled in size in 1919. The value of city lots had raised several times.

The people of Newdale were very progressive and hard workers and had a desire to make the area a truly good place to live. In December 1919, an 8-room, brick school house was completed on a piece of land donated by Sam Schwendiman, where the Newdale City Park is today. Leigh Chantrill was a young boy at the time, and later said: "It was really exciting when the new school house was completed enough so we could use it for school and church meetings". Its classrooms were heated by wood stove, and had no indoor plumbing. A playground was also built including swings and a baseball diamond. Students would attend school in Newdale from 1st to 8th grade, and then go to school in Teton for freshman and sophomore years, and Sugar City for high school. The Newdale school house was also used for LDS church meetings until a church house was built in 1952.

An agriculture depression in the early 1920s hurt the town, and many families lost their homes and farms to creditors, and were forced to leave Newdale. In 1924, when John Schwendiman was asked to be bishop of the Newdale LDS ward, he said this about the state of the town: “Newdale was half deserted. Some houses had burned down. Others were moved away and several were empty. The town was bonded for over $100,000 for the school house and water works.” The Great Depression of the 1930s had similar negative effects. The beat dump closed down but the potato industry would continue to expand. By 1944, only $1000 had been paid off in principal on the cities debts. The 1940s brought a new generation of farmers, with a lot of thought and effort being put towards irrigation. They used wells and dams. Sprinkler irrigation would double or triple the amount of usable farm land in the area.

An LDS church house was completed and dedicated in 1952.

In 1967, the City of Newdale purchased the Newdale School house and property, which was no longer in use, and turned it into a city park over the next few years. It was also at this time that the streets of Newdale were officially named (from West to East): R.R. Street (Railroad), Main Street, Church Street, Park Street, and Schwendiman Park Road.

A swimming pool was built in Newdale with a new well to supply the water. The pool failed shortly after opening, due to lack of patronage. Newdale wells produce warm water.

Newdale is the nearest city to the Teton Dam, which failed on June 5, 1976. Newdale did not receive any flooding or damage, due to its elevation and position relative to the dam.

"I remember riding in the old Nash truck to deliver grain to the Farmer's Warehouse where Walter's potato business is now located. My Uncle Leigh Martineau drove the truck which was an army surplus truck from World War I. It traveled so slow that they would trail a wagon behind it loaded with wheat, about one hundred sacks on the truck and trailer. He would wait in a long time to get unloaded." - J. Leigh Chantrill, story took place approximately 1918 - 1922.

"In the prohibition days when it was illegal to sell liquors in any form, the following took place in Newdale: Two young men from Newdale, Lee Clark and Delray Huff, went to work for the government as informants, or stool pigeons as they were called. They would buy liquor from the bootleggers, then they would report the bootleggers to the government law enforcement officers. Lee Clark and Delray Huff worked for the government and turned in a Mr. McCarrel and his fellow bootlegger a Mr. Fox. Fox and McCarrel came up to Newdale one night to shoot Lee Clark and Delray Huff. Gerald Clark, who was Lee Clark's brother, got involved in the plot and was shot and killed just south of the Newdale store, by Fox and McCarrel. It was a sad time for the people of Newdale, because Mr. Gerald Clark had a family. After a long trial in the St. Anthony Court House, Mr. McCarrel and Mr. Fox were sent to the State Penitentiary. The headstone at the grave of Gerold Clark, in the Teton-Newdale Cemetery shows that he died in 1930." - Author Unknown, Source: In the book compiled by Norman and Ruby Ross.
