Formation of plasma between a metallic pin and water electrode is investigated. A streamer to spark transition occurs when the pin is anode. The influence of the water surface deformation due to the ionic wind on the spark formation is discussed. High speed photography indicates that the streamers just before sparking are always branched near the water surface. Optical and electrical characteristics of a stable filamentary glow-like discharge regime, ignited after electrical breakdown with currents between 20 and 120 mA are studied.
