The Gateway State Bank began operating as Goose Lake State Bank in 1907 in the pictured brick and stone building. The Clinton County bank survived the depression, even expanding in 1936 when it absorbed a failed bank in nearby Charlotte. In 1980, the bank charter was moved to Clinton and renamed Gateway State Bank. While the bank has occupied several locations in Clinton, it has remained in its original office in Goose Lake for the entirety of its 100-plus-year history.
Mail equipment was transferred to the new post office in the Clinton County community of DeWitt on Friday, July 14, 2000, and the new facility was officially opened to customers the following Monday. The new post office offered dedicated customer parking, a 24-hour lobby, and about twice the square footage of the previous location.
The previous post office was constructed in 1936, one of several built across the state as part of the Works Project Administration. After sitting vacant for nearly a year, the City of DeWitt purchased the building and renovated the interior for use as the City Hall.
On May 15, 1901, Clinton Mayor George D. McDaid wrote to the Andrew Carnegie Foundation requesting funds for a new library building to be constructed in the eastern Iowa community. The result was a $45,000 grant provided the city provided land for the library and the annual budget was not less than 10% of the grant amount. Ground was broken for the new building on June 24, 1903, and the library opened to the public on November 9 the following year. More than 5,400 books were checked out in the library’s first month of operation.
In 2005, the group Preservation Iowa added the Clinton Public Library to its list of the state’s most endangered buildings as the city was considering building a new library facility at that time. A proposal in 2010 to allocate up to $10 million in bonds to construct a new library at a former elementary school site was soundly defeated. In December, the Library Board president told the Clinton Herald plans to renovate or move the library had been tabled for the immediate future.
