Dams help in preventing floods. They catch extra water so that it doesn’t run wild downstream. Dam operators can let water out through the dam when needed. The first upstream flood control dam was built in 1948, Cloud Creek Dam in Oklahoma.A structure, built across a river or stream, that limits the amount of water and sediment moving downstream. The dam reduces the risk of flooding for downstream communities by releasing water in controlled amounts. Dams also store water for groundwater recharge.Dams block the flow of water . Water is trapped behind the dam, forming a pond or a lake . Dams can be useful for preventing floods . They are also used to create reservoirs for drinking water and to manage water used to create hydroelectric power.

Do dams reduce water flow?
Many dam systems are used to abstract water from the river for irrigation and other uses, sometimes on a very large scale. This does reduce the average flow downstream. Depending on the site, filling the lake might take a year or more, which could have severe consequences on people downstream.
How does a dam save water?
During times of excess water flow, dams store water in the reservoir; then they release water during times of low flow, when natural flows are inadequate to meet water demand.
What’s the purpose of a dam?
Dam Basics
The purpose of a dam is to impound (store) water, wastewater or liquid borne materials for any of several reasons, such as flood control, human water supply, irrigation, livestock water supply, energy generation, containment of mine tailings, recreation, or pollution control.
What are advantages of dams?
- WATER FOR DRINKING AND INDUSTRIAL USE.
- IRRIGATION.

Are dams used to prevent flooding during storms?
Dams allow water to be released in controlled amounts thereby reducing the risk of severe floods and mudflows during storms to Los Angeles residents living within the floodplain. Dams also store water which can later be used to replenish ground water basins.

How does a dam slow a river?
Dams change the way rivers function. They can trap sediment, burying rock riverbeds where fish spawn. Gravel, logs, and other important food and habitat features can also become trapped behind dams. This negatively affects the creation and maintenance of more complex habitat (e.g., riffles, pools) downstream.

Why do dams reduce river flow?
By diverting water for power, dams remove water needed for healthy in-stream ecosystems. Stretches below dams are often completely de-watered. Dams prevent the flow of plants and nutrients, impede the migration of fish and other wildlife, and block recreational use.
How do dams impact the water cycle?
Dams = water loss
The evaporation also affects the microclimates of the surrounding areas, disrupting natural temperature fluctuations, ecosystems and habitats. For example, increased evaporation in the region of a large dam changes the moisture concentration of the air, leading to increased heavy rainfall.
How does a water dam work?
A conventional dam holds water in a man-made lake, or reservoir, behind it. When water is released through the dam, it spins a turbine connected to a generator that produces electricity. The water returns to the river on the downstream side of the dam.
How do dams help in conserving and managing water?
They help in conserving and managing water by storing large amount of water so that when there is no rain and your crops are too dry you can get water from the dam and it gets water from the river and rain.
Why are dams built?
People build dams to control water—to make sure the right amount is at the right place at the right time. River water rises behind dams, forming artificial lakes called reservoirs.
