• The upstream of Wampu Waters is a habitat for various fish species including Tor spp fish. Fluctuating conditions of habitat will greatly affect the existence of fish as diversity, uniformity, dominance, and abundance of fish. This research was conducted to determine of the condition of habitat and diversity of Tor spp fish in the upstream of Wampu waters. Measurement of habitat conditions by measuring current velocity, depth, temperature, visibility, DO and pH. The method was used n this research is descriptive post facto with fishing using backpack electrofishing units, 12 volts and 9 amperes of battery with the multiple-pass depletion operation technique. Habitat conditions in both research locations are good and appropriate to support the life of fish of Tor spp. Tor fish species was found are Tor soro and Tor tambroides with low fish diversity index of Tor spp of 0.5 for the Bahorok River and 0.61 for the Berkail River, lowest evenness index of 0.09 was found in the Bahorok River and 0.11 in the Berkail River and lowest dominance index of 0.17 were found in the Bahorok River and 0.2 in the Berkail River.
