No, streams do not always flow into rivers. Streams are smaller bodies of flowing water than rivers that are generally found in valleys or other low-lying locations.
Precipitation (such as rain or snow), subterranean springs, and melting snow or ice are all sources of water for them. Streams can either flow into larger amounts of water like rivers or lakes, or they can dry up and perish entirely.
A stream’s route can be impacted by a number of elements, including the slope and form of the ground, the kind of rock or soil through which it runs, and the amount of available water.

How human activity can alter the flow of streams
Various human activities affect stream flow. Some examples include:
Dams and reservoirs
Humans can produce a body of standing water by blocking the flow of a stream using dams and reservoirs. This can change the stream’s normal flow and disturb the environment downstream.
Channelization
Humans can also influence stream flow by channelizing them or straightening and deepening the stream bed to allow for quicker water flow. This can cause erosion and sedimentation difficulties downstream, as well as disrupt the natural habitat of plants and animals.
Land use changes
Changes in land use, such as urbanization or agriculture, can also have an impact on stream flow. Development can result in the paving over of natural surfaces, reducing the quantity of water absorbed by the ground and increasing the amount of runoff that runs into streams. Agriculture can also cause greater runoff if fields are not maintained appropriately.
Water withdrawal
Water removal from streams and rivers for irrigation, industrial usage, and other activities can also cause changes in their flow. If too much water is extracted, the volume of water in the stream will be reduced, disrupting the environment.
Factors that influence the flow of streams into rivers
Precipitation
Rainfall and snowfall affect stream flow into rivers. Higher precipitation increases flow, whereas lesser precipitation decreases flow.
Temperature
As the temperature of the air and ground rises, so does the rate of evaporation, which might result in lesser stream flow. Conversely, when the temperature drops, so does the rate of evaporation, which might result in increased stream flow.
Topography
The slope and height of the ground, as well as the topography of a location, can impact the flow of streams into rivers. Faster flow can be caused by steep slopes, whereas slower flow can be caused by flatter places.
Geology
The geology of a region can also influence stream flow. Porous soils, for example, may have higher rates of infiltration, resulting in decreased stream flow.
Vegetation
Plants having deep root systems, such as trees, can assist in holding water in the soil and minimize the quantity of water that flows into streams and rivers.
Land use
The way land is used can also have an influence on stream flow. Urbanization and the growth of impermeable surfaces such as roads and buildings, for example, can result in greater runoff and higher stream flow.
Exceptions to the rule: when streams don’t flow into rivers
The rule that streams always flow into rivers has a few exceptions. A larger stream or river may flow into a smaller body of water rather than the other way around in rare instances. This can occur due to a variety of factors, such as changes in terrain or adjustments in the flow of the water body through time.
One example is when a river divides into two different channels, one of which flows into a smaller stream or body of water. When the smaller stream or body of water has a lower elevation than the river bed, the river water flows downhill into it.
Another instance is when a stream or river is dammed or redirected, altering its natural flow pattern. If a dam is erected on a river, for example, the water may be held back, causing the downstream flow to reduce or halt entirely. Similarly, if a river is redirected for irrigation or other uses, it may no longer flow back to its original location.
While streams normally flow into rivers, there are a few outliers that can develop owing to changes in geography, adjustments in the path of the water bodies, or human involvement.
The journey of water from the stream to the river
Water travels from stream to river after being gathered in a stream, which is a tiny, narrow body of fresh water that runs downwards and is often nourished by rain and snowfall. As the stream travels downhill, it collects additional water from tributaries (smaller streams that pour into it).
As the stream expands and widens, it becomes a river. The confluence of several smaller streams and tributaries forms larger rivers like the Mississippi and the Amazon.
Water can not travel in a straight line from the stream to the river since rivers can sometimes flow into other bodies of water, such as lakes or oceans. The world’s major rivers, such as the Nile and the Yangtze, flow into the sea, taking with them fresh water and silt accumulated along the way.
Overall, the voyage of water from the stream to the river entails the collecting and convergence of smaller quantities of water into a single, bigger river, which can eventually flow into other bodies of water, such as lakes or oceans.
