when did the us get the ohio river valley
Ohio River The 1768 Treaty of Fort Stanwix opened Kentucky to colonial settlement and established the Ohio River as a southern boundary for American Indian territory.[10] In 1774, the Quebec Act restored the land east of the Mississippi River and north of the Ohio River to Quebec, in effect making the Ohio the southern boundary of Canada. This appeased the Canadien British subjects but angered the Thirteen Colonies. Lord Dunmore's War south of the Ohio river also contributed to giving the land north to Quebec to stop further encroachment of the British colonials on native land. During the American Revolution, in 1776 the British military engineer John MontrÃ©sor created a map of the river showing the strategic location of Fort Pitt, including specific navigational information about the Ohio River's rapids and tributaries in that area.[11] However, the Treaty of Paris (1783) gave the entire Ohio Valley to the United States.
Cuyahoga River The Cuyahoga River[7] (/ˌkaɪ.əˈhɒɡə/ KY-ə-HOG-ə, or /ˌkaɪ.əˈhoʊɡə/ KY-ə-HOH-gə[8][9][10][11]) is a river in the United States, located in Northeast Ohio, that feeds into Lake Erie. The river is famous for having been so polluted that it "caught fire" in 1969. The event helped to spur the environmental movement in the US.
