Effects of the Leptonic CP violating phase,δ, on 3 generation neutrino oscillation rates and asymmetries are discussed. A figure of merit argument is used to show that our ability to measure the phase δis rather insensitive to the value of θ13 (for sin22θ13\gsim0.01) as well as the detector distance (for very long oscillation baselines). Using a study of νμ→νe oscillations for BNL-Homestake (2540 km) we show that a conventional horn focused wide band neutrino beam generated by an intense 1-2 MW proton source combined with a very large water Cherenkov detector (250-500 kton) should be able to determine δto about ± 15^∘ in 5× 107sec of running. In addition, such an effort would also measure the other oscillation parameters (θij,Δm2ij) with high precision. Similar findings apply to a Fermilab-Homestake (1280 km)baseline. We also briefly discuss features of Superbeams, Neutrino Factories and Beta-Beams.
