The Baikal Neutrino Telescope: Results, Plans, Lessons
  We review recent results on the search for high energy extraterrestrial neutrinos, neutrinos induced by WIMP annihilation and neutrinos coincident with Gamma Ray Bursts as obtained with the Baikal neutrino telescope NT-200. We describe the moderate upgrade of NT-200 towards a ~10 Mton scale detector NT-200+. We finally draw a few lessons from our experience which may be of use for other underwater experiments.
