Milk River (Alberta–Montana)

The Milk River is a very long river. It flows through Montana and Alberta. The water looks white like milk. This is because of soft clay in the ground.

The river starts in the high Rocky Mountains. It flows past many hills and cliffs. You might see sand dunes there too. Many birds live near the water. You can find owls and hawks there.

Some snakes and frogs live in the grass. The river is a big home for them. It is a very busy place for nature.

The Milk River is a very long river. It flows through Montana in the U.S. and Alberta in Canada. It starts in the Rocky Mountains. The river flows into the Missouri River.

Why is it called the Milk River? Captain Meriwether Lewis gave it this name. He saw fine clay and silt in the water. This makes the water look white. The river flows through dry lands and grasslands. You can see cliffs, sand dunes, and rocky hills there.

Many animals live near the river. You might see pronghorns or different kinds of snakes. Many birds live in the area too. These include owls, hawks, and falcons.

People use the water in many ways. A canal moves water from the St. Mary River. This helps people have water to drink. It also helps farmers water their land. The river is a big part of the land. It flows through many places like Writing-on-Stone Provincial Park. It even passes near the Fort Belknap Indian Reservation.

The Milk River is a very long river in North America. It flows through the U.S. state of Montana and the Canadian province of Alberta. This river is a part of the Missouri River system. It starts high up in the Rocky Mountains. The water travels through a dry area called a semi-arid watershed. This watershed covers parts of Alberta, Saskatchewan, and Montana. It is one of the few parts of the Mississippi River watershed that reaches into Canada.

Many different paths make up this river. In Montana, the South Fork and Middle Fork join together. These forks start in the mountains near Glacier National Park. Much of the water in the North Fork comes from the St. Mary River. A canal and a special pipe called an inverted siphon move the water. The main stream flows east into Alberta. It passes Writing-on-Stone Provincial Park before turning back into Montana. It flows past the town of Milk River and the Fresno Dam.

Captain Meriwether Lewis gave the river its name. He was part of the Lewis and Clark Expedition. He saw that the water looked white. This happens because of fine clay and silt in the water. These tiny bits of dirt come from soft rocks in Alberta. These rocks are part of the Foremost, Oldman, and Dinosaur Park formations. In 1818, the U.S. and Britain swapped some land. This changed which part of the river belonged to each country.

People use the river water in many important ways. In 1905, a plan was made to move water to the North Fork. This water helps 14,000 people have clean water to drink. It also helps water ranchland in the Hi-Line region of Montana. In 1908, a famous court case happened here. It was called Winters v. United States. This case helped decide water rights for the Fort Belknap Indian Reservation.

The land around the river has many different shapes. You can see grasslands, cottonwood groves, and sand dunes. There are also cliffs, badlands, and rocky hills. Many animals live in these habitats. You might see pronghorns or northern leopard frogs. Many birds live here too. These include the burrowing owl, sage grouse, and prairie falcon. You might even see a hawk or a different kind of sparrow.

The Milk River is a significant tributary of the Missouri River. It flows through two different countries. It travels through the U.S. state of Montana and the Canadian province of Alberta. The river drains a semi-arid watershed. This means the area is relatively dry with little rain. This watershed is quite large. It covers parts of Alberta, Saskatchewan, and Montana. It is a unique geographic feature. It is one of the few parts of the Mississippi River watershed that extends into Canada.

The river is formed by several distinct branches or forks. In Glacier County, Montana, the South Fork and Middle Fork join together. Both of these forks rise in the Rocky Mountains. They start just east of Glacier National Park within the Blackfeet Indian Reservation. The North Fork is also an important part of the system. Much of the water in the North Fork is diverted. It comes from the St. Mary River. This water moves through a canal and an inverted siphon. An inverted siphon is a type of pipe used to move water. This helps manage the flow of the river system.

After the forks join, the main stream flows east-northeast. It enters southern Alberta. There, it meets the North Fork of the Milk River. The river then flows past the town of Milk River. It also passes Writing-on-Stone Provincial Park. The river changes direction and turns southeast back into Montana. It runs along the north side of the Sweetgrass Hills. Later, it turns south and passes through the Fresno Dam. It continues east past the town of Havre. It then flows along the north side of the Fort Belknap Indian Reservation. Near Malta, the river turns north and then southeast again. It flows past Glasgow before joining the Missouri River in Valley County, Montana. This happens downstream from the Fort Peck Dam.

The river has a very interesting history and a unique name. Captain Meriwether Lewis named the river. He was a member of the Lewis and Clark Expedition. He wrote about the river in his journal. He noticed the water had a milky appearance. This look comes from suspended clays and silts. These fine-grained sediments are washed into the water from erosion. The erosion comes from soft, clay-rich rocks in the southern Alberta basin. These include the Foremost, Oldman, and Dinosaur Park formations. During Lewis's time, the area was part of the United States. This was because of the Louisiana Purchase. However, in 1818, U.S. negotiators made a land swap. They traded a portion of the Milk River watershed north of 49° north latitude. In exchange, they received a parcel of the Red River of the North drainage from British North America.

Human use of the river is very important for the region. In 1905, a project was authorized to move water. This project brings St. Mary River water into the North Fork. This water provides drinking water for 14,000 municipal users. It also provides irrigation for ranchland. This ranchland is located along Montana's Hi-Line region. The river has also been central to legal history. In 1908, the waters were part of a United States Supreme Court case. This case was known as Winters v. United States. The ruling helped clarify water rights for the Fort Belknap Indian Reservation. It became a precedent-setting decision for Indian reservations.

The landscape around the Milk River is diverse. The area contains three different drainage basins. These are the Lost River Valley, the Milk River basin, and the Kennedy Coulee. The terrain includes native grasslands and riparian cottonwood groves. You can also find badlands, coulees, and cliffs. There are sand dunes and rocky outcrops as well. This variety of land creates many different habitats. Many animals depend on these environments. You can find pronghorns and northern leopard frogs here. Various snakes also live in the area, such as bull snakes and western hognose snakes. Prairie rattlesnakes are also found in this landscape.

Many different bird species live in the Milk River area. Some of these include the mountain plover and the burrowing owl. You might see a sage grouse or a loggerhead shrike. Other birds include the Sprague's pipit and the long-billed curlew. The area also supports the ferruginous hawk and the prairie falcon. Other species include the willet, marbled godwit, and lark bunting. You can also find the Baird's sparrow, McCown's longspur, and the chestnut-collared longspur. This large variety of wildlife shows how important the river and its watershed are to the natural ecosystem.
