Focusing on the land drainage, flood control projects, this study show the impact of great flood on the Mississippi river basin. After 1880s, The Yazoo-delta had grown dramatically. The population had increased and the amount of land in cultivation had nearly doubles, but white planters agreed that the South should not rely on the negro for its prosperity. Finally, this study concludes that the oppression experienced during the flood drove many blacks to abandon the delta and move to northern cities. On the contrary, in south Minnesota, drainage work were began in 1880s and 1890s, large areas of wet prairies were acquired by northern european settlers. They maintained close links with their home. But since great flood of 1927, farmers were reducing acreage of drainage farm land, the state authority launched a project to acquire wetland areas threatened by agricultural drainage.

However, this study is neither a history of legislative power politics nor ahistory of the federal river policy. Focusing on the local authorities improvingecological protection against great flood along the lower Illinois River, this study showshow the nature-centered river system initially developed as a response of the localdrainage and levee districts. I made use of the archival materials on the local landdistricts, which reveals that because of the general flood and operating costs for landdrainage at high level, landowners were delinquent in paying off the principal andinterest due on drainage bonds. As a consequence, the reversion of reclaimed land toits natural functions proceeded rapidly through the Soil and Water ConservationDistricts.
