The Genesee River's name is derived from the Seneca tribe word meaning good valley or pleasant valley. It flows northward through western New York from its source south of the town of Genesee in Pennsylvania and empties into Lake Ontario north of the City of Rochester, New York. The river drains about 2500 square miles (6,500 km²). Falls along the river are within the gorge of Letchworth State Park (the Grand Canyon of the East) near Portageville, New York and within Rochester, where they provided power to 19th century industry. A dam at Mount Morris is the largest flood control dam east of the Mississippi. It has greatly reduced flood damage in the lower Genesee Valley; its capacity has never been exceeded. The dam was completed in 1952.
The river was the original source of power and commerce in the Rochester area. Many grist mills along the river grind more flour than anywhere else in North America, giving Rochester her nickname “Flour City”.

[edit] Geology
Main article: Genesee River: Glacial Geology
The present river valley has been modified extensively from preglacial river valleys. The original river had two branches. The east branch has a larger preglacial valley. It runs south of Mount Morris. It was completely blocked by extensive terminal moraines just south of Dansville, so most of the upper section was diverted toward the Susquehanna River system. Now only a small creek flows in what is left of this large valley. The west branch, which was smaller, is now the Genesee River above Mount Morris.
The present river is the western branch of the preglacial system. Along its entire course, the rock layers are tilted to the south an average of forty feet per mile, so the river flows across progressively older bedrock as it flows northward. It rises in the highlands of the Allegheny Plateau in conglomerate, sandstone and shale rocks of Mississippian and Pennsylvanian age, passing through and often exposing older rocks as it drops. At Letchworth it exposes shales, siltstones and some limestones of Devonian age. At Rochester it again cuts a canyon with three more waterfalls in limestones and shales of Silurian age. The river is a highly favored area for fossil collectors, as one can find a great variety from a very long time span, within the short course of the river.
[edit] History
The Genesee River Valley westward to Lake Erie and the Niagara River was the homeland of the Seneca Nation of the Iroquois Confederacy, also known as The Keepers of the Western Door, as they were the westernmost nation. The Senecas were gradually divested of their homelands and now have just three small reservations left.
The falls at present day Rochester were likely the main reason for the city's existence, as they provided water power for mills. When the Erie Canal opened in 1825 the mills could ship their products cheaply to New York City, and business boomed. Rochester became known as Flour City.
Most of New York west of the Genesee River was part of the Holland Purchase after the American Revolution. From 1801 to 1846 the entire region was sold to individual owners from the Holland Land office in Batavia, New York. Today the region derives its name from the river and is generally referred to as Genesee Country. To the east of the river is the Finger Lakes geographic region.
Following the spectacular success of the Erie Canal, completed in 1825, a group of investors dreamed of connecting the Erie Canal to the Mississippi River System by building a new canal from the Erie, near Rochester, up the Genesee Valley, across to the Allegany River at Olean, thence downward to the Ohio and Mississippi valleys. Construction of the Genesee Valley Canal was begun in 1836, and new sections extended upriver, southward until 1880. During that time the canal was an important commercial route for the valley. The canal was plagued by frequent flood damage and the final leg down the Allegany River was never completed.
The most difficult section to build was the bypass around the gorge and falls at present day Letchworth. The canal followed the old Native American portage route, which necessitated many locks. These old locks can still be seen near Nunda. The project was abandoned and the right of way was sold in 1880. The property became the roadbed for the Genesee Valley Canal Railroad, which eventually merged with the Pennsylvania Railroad.
In 1852 a wooden railroad bridge was built over the Upper Falls at Portageville. It was the largest of all wooden bridges built at the time. The wood from 300 acres (1.2 km²) of trees was required for its timber.
The "great flood of 1972", spawned from the remnants of Hurricane Agnes, wreaked devastation upon the county with the most concentrated damage occurring at and near the Village of Wellsville. Wellsville is the largest village in the county, which contains no cities, and is the junction of many foothill streams including Dyke Creek feeding the Genesee River from the east and Andover. Since Dyke Creek had also exceeded its bank capacity it aided in producing a rapid and huge pool of water at the center of the Village of Wellsville. The damage area continued downstream through Scio and Amity until the valley widened to accept the large flow of water in the lesser populated area. Erosion of topsoil during this flood reduced the agricultural ability of the county with serious consequence which eliminated many small farmers immediately.
