Delhi Dam
Delhi Dam, also known as Hartwick Dam, was an embankment dam on the Maquoketa River 2.5 km southwest of Delhi, Iowa that created Lake Delhi. The dam was over-topped and subsequently failed on July 24, 2010 after a period of heavy rain.
The dam and lake are part of the Turtle Creek Recreation Area, and is owned by a local community group.〔http://thegazette.com/2011/11/06/ownership-switch-to-aid-delhi-dam-rebuilding-effort/〕
==History==
The dam was built between 1922 and 1929 by the Interstate Power Company for hydroelectric power production, but its generators ceased operating in 1973 shortly before the Lake Delhi Recreation Association took ownership. Since then, it has been used for recreation. Several floods in 2008 caused an estimated $500,000 in damages to the dam and its floodgates. In October 2008, the Association signed a partnership with Modern Hydro to have the power plant's turbines refurbished and recommissioned.〔 The new power plant was to have two turbine generators with a 1.5 MW capacity able to produce 3 GWh of electricity annually for sale to the local power utility. $1.5 million in funding was sought by the Iowa Power Fund and power production was expected as early as 2010. The dam was cited for minor problems during a 2009 Iowa Department of Natural Resources safety inspection.〔 〕
