This leads me to doubt that Tilapia can be found in colder water like the Snake or Oneida, however Blue lake is warm spring feed and has a suface temp of close to 70 deg. in the winter and I personally have caught many there.

Tilapia are unable to survive in low temperate climates because they require warm water. The pure strain of the Blue Tilapia, Oreochromis aureus, has the greatest cold tolerance and dies at 45 °F (7 °C) while all other species of tilapia will die at a range of 52 °F (11 °C)-62 °F (17 °C). As a result, they cannot invade temperate habitats and disrupt native ecologies in temperate zones; however, they have spread widely beyond their points of introduction in many fresh and brackish tropical and subtropical habitats, often disrupting native species significantly.[url "http://en.wikipedia.org/wiki/Tilapia#cite_note-15"][16][/url] Because of this, tilapia are on the IUCN's 100 of the World's Worst Alien Invasive Species list.[url "http://en.wikipedia.org/wiki/Tilapia#cite_note-16"][17][/url] In the United States, tilapia can live only in extreme southern Florida and a few other isolated areas such as power plant discharge zones.
