Richfield is a town located in Otsego County, New York, USA. This township was formed from Otsego in 1792. It then included the townships of Exeter and Plainfield, which were set off from it in 1799. The surface is rolling and moderately hilly with a mean elevation of 150 to 200 feet above Canadarago (or Schuyer) Lake. Several wooded mountain peaks near the eastern boundary rise 300 feet higher. Canandarago Lake, the northern portion of which is within this township, lies in a deep valley and is fed by a number of streams which enter it from the northwest. Its outlet is Oaks Creek, through which its waters flow southward into the usquehanna river. The settlement of this region was rapid as soon as the close of the Indian wars made it safe to establish homes in the wilderness. The northern portion of Otsego county was regarded with especial favor in consequence of its beautiful lake scenery, fertile soil, good timber and eligible millsites and water privileges.
