Moreover, our neighbors to the north are currently looking at an estimated cost of over a billion dollars to fix their flooding problems Truckee River Flood Project, Because most ranches have been purchased and developed in the Reno area, the flood damages there in were over 30 times more costly than in the Carson Valley.
Marilyn Newton, Reno Gazette Journal. According to the Regional Floodplain Management Plan , Carson watershed communities must promote incentives such as conservation easements to help floodplain property owners keep their lands in agricultural and other open space land uses.
Otherwise there is strong possibility some of our floodplains will be lost to additional development. It will take citizen involvement and the cooperation of local and state agencies to find ways to help preserve our existing floodplains.
Although current local, state and federal laws allow for development within the floodplain, the cities of Reno and Sparks have found that this can result in devastating impacts during flood events. By acting now and helping those who own these important floodplain areas, we can avoid the immense costs associated with trying to protect future developments that could be located there.

NV Bureau of Mines and Geology, Please contact Extension's Communication Team for assistance. Yet these practices may actually increase the intensity of water flow. This can exacerbate flooding downstream and degrade river ecosystems. In , we interviewed 36 residents and farmers in the Deerfield River watershed in western Massachusetts. This area has experienced significant flooding in recent years.
Some residents proposed that all the land bordering rivers should be restored to natural forests. The forests would increase water infiltration, protect banks form erosion and reduce flooding. This practice, however, could also have negative impacts on farmers and the local economy. Effective stream governance strategies often require that all stakeholder groups have their goals and concerns addressed. Any river governance system should identify who has the authority to manage river and stream corridors.
This person or group sets rules that determine the flood risk for farmers and downstream communities. The potential impacts of each management strategy should be weighed and analyzed for specific floodplain areas. This allows managers to make informed decisions while balancing the needs of a diverse set of stakeholders. A floodplain, or flood plain, is flat or nearly flat land adjacent to a stream or river that experiences occasional flooding.
Floodplains are formed in two ways: by erosion; and by aggradation. An erosional floodplain is created as a stream cuts deeper into its channel and laterally into its banks. Floodplains are beneficial for wildlife by creating a variety of habitats for fish and other animals. In addition, floodplains are important because of storage and conveyance, protection of water quality, and recharge of groundwater. Liquid water is the major agent of erosion on Earth.
Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion. When rivers flood in the middle valley the cover an area of land known as the flood plain. When they flood velocity is slowed and deposition of any rocks being transported is encouraged.
This deposition leaves a layer of sediment across the whole floodplain. Often, floodplains contain a mixture of wetland types. Hydric or water-loving soils are typical of these environments. These dark-colored soils are rich in nutrients, providing ideal conditions for crop production despite the flooding risks. During the early days of European settlement, many floodplain areas were drained so that these areas could be used by farmers.
Corn has the distinction of being grown in more countries around the world than any other crop. The United States is the primary producer and exporter of corn globally. The majority of corn grown in the United States is used for feed and other residual uses. Today's farmers are able to choose from multiple hybrids, developed for specific conditions.
Floodplains such as the Illinois River valley are highly productive river systems. This fact makes these areas attractive for agriculture.
