The town is located on the Canadian Pacific Railway Soo Line, at an elevation of 572 metres (1,877 ft) above sea level.

The town was founded as an unincorporated village and named after the yellow prairie grass that surrounds the area.

Like other Saskatchewan rural communities the town has seen a large portion of young residents leave to find work in other parts of Canada[1].

Yellow Grass has grown little since the boom years in the early twentieth century; many resident families are descendants of the original pioneers.

A substantial number of residents are employed in the nearby city of Weyburn, many in the manufacturing sector, retail sales, the health region, and in the oilfields.

The second, and by far the biggest boom, started in the post war years and continued until the late 1920s as the trading area of the region.

[2] The agricultural industry made a recovery in the post-World War II years with record setting crops, and the community recovered its municipal services.

In the last few decades the economy has been relatively stagnant, with most of the town's youth leaving to find employment in larger communities.

Pressures on farming due to weather and high fuel and equipment costs have been keeping the growth of agriculture in check.

Yellow Grass is in a region of Canada known as the Great Plains, and situated well into the Canadian Prairies.

These lakes form as a result of the spring runoff when the snow melts, and vary in size depending on annual rainfall.

Extreme high and low temperatures in Yellow Grass have ranged from 45 °C (113.0 °F) in July 1937 to −45.6 °C (−50.1 °F) in January 1916.

In 1928 the plant was sold to the Montreal Engineering Company, and the town was hooked into the Soo Line power grid.

In 1971 The Royal Canadian Legion established a memorial plot and named it the Field of Vanquished, to honour the Yellow Grass citizens who perished in war.

The Southeast Regional Library – Yellow Grass Branch, opened on January 31, 1967 after years of lobbying efforts, including letters and petitions.

The town of Yellow Grass first started thinking about sanitation in the early 1900s when cesspools were designated for controlled removal of sewage.

Due to the number of accidents on Highway 39, the need for hydraulic extrication tools arose, and in 2014 YGFR purchased Jaws of Life.

When the North-West Mounted Police closed down their detachment, a holding cell was constructed in the power plant.

Today Highway 39 travels through town making a quick and convenient drive to Weyburn, as well as Regina and Moose Jaw.

The overseer position is similar to that of a mayor except that there is no town council, and the primary duty is to file the annual financial statements.

John Morrison, a Yellow Grass area farmer, ran for the Progressive Party of Canada was first elected in 1921 and defeated in 1925.

A number of residents have run for provincial legislature as well, most recently including Barry Chase in Alberta.

All styles of organized baseball have been played including fastpitch softball, slow pitch, and hard ball.

Yellow Grass would send two men to fight in the Second Boer War; both returned from combat safely.

During the First World War 42 men went overseas to fight, unfortunately 14 would perish in combat, marking the most significant loss for the town during wartime.

During both world wars, most of the organized clubs and sports teams halted operations, and the remaining residents focused on farming.
