b. December 3, 2004 at 06.00 am weir Lodoyo provide standby signal III / red for discharge = 1,016 m3 / sec. c. The operation of the sluice weir Lodoyo already done on December 2, 2004 beginning at 1:00 am. d. The rain did not stop so that the discharge tends to increase steadily even on December 3, 2004 at 08:30 pm at the weir Lodoyo out flow discharge reached 2,115 m3 / sec. e. Areas affected by the inundation is under flood water level of Bogel River, so that when water is abundant and several tributaries berms fail then there is a pool of sufficiently high (the highest inundation reached El. 139,87m, while areas were inundated elevation 137.00 - 139.00 m). f. Based on the evaluation, the flow capacity of Bogel River in the upstream (15 m3 / s), while in the central part of 20 m3 / s, and upstream tributaries after meeting capacity up to 110 m3 / sec. The estimated calculation of flood discharge reaches + 190 m3 / sec. (Jasa Tirta I Public Corporation,2005. Flood Audit Report) 2. Impact of Fatalities of Flood 2004 There are six (6) people died in the district Sutojayan, Blitar in the event of flooding. (Jasa Tirta I Public Corporation,2005. Flood Audit Report) FIGURE 2.
