The Miami Conservancy District is a river management agency operating in Southwest Ohio to control flooding of the Great Miami River and its tributaries. It was organized in 1915 following the catastrophic Great Dayton Flood of the Great Miami River in March 1913, which hit Dayton, Ohio particularly hard. Designed by Arthur Ernest Morgan , the Miami Conservancy District built levees , straightened the river channel throughout the Miami Valley , and built five dry dams on various tributaries to control flooding. The district and its projects are unusual in that they were funded almost entirely by local tax initiatives, unlike similar projects elsewhere which were funded by the federal government and coordinated by the U.S. Army Corps of Engineers .
73-648: The 1913 flood has been ascribed in part to the 1912 eruption of Mount Katmai and its daughter volcano Novarupta in Alaska. In one of the greatest recorded volcanic events, Novarupta emitted enough fine ash into the atmosphere to block sunlight and cool the climate of the Northern Hemisphere that winter. The success of the Miami Conservancy District helped to inspire the development of the much larger Tennessee Valley Authority during
146-520: A VEI of 3, and possibly involved phreatic eruptions . Following the eruption, thousands of fumaroles vented steam from the ash, creating the Valley of Ten Thousand Smokes . In 1919, geologists noted a lake covering a large part of the caldera floor. By 1923 the lake was gone and numerous fumaroles , mud pots , and a large mud geyser had replaced it. The lake has since refilled to a depth of over 800 ft (240 m). Small glaciers have formed on

The inhabitants of the town of Kodiak , with ash falling on them, were led to the United States Revenue Cutter Service revenue cutter USRC Manning where they sheltered and were cared for by the crew, remaining in the harbor because Captain Perry determined "an attempt to leave here would be unwise" because the eruption made navigation dangerous. The withdrawal of magma beneath Katmai resulted in

Between 9 to 11 inches (23 to 28 cm) of rain fell over five days, March 25 to 29, 1913. An amount equivalent to about 30 days' discharge of water over Niagara Falls flowed through the Miami Valley during the ensuing flood. In the Great Miami River Valley, 360 persons died, about 200 of whom were from Hamilton. Some drowned, some were washed away and never found, others died from various diseases and complications, and some committed suicide because of severe losses. Damage in
