In the Nova Amaterska cave was discovered new parts in TNO passage with aim of finding of further part of Bila Voda creek riverbed. Active stream was not found. In consequence low level of water was interconnected Krematorium with Chrochtadlo across semisump between both parts. In the 13C cave was pumped out sump of Bila Voda creek between 13C and Spiralka cave and 175 m of passages was measured. In the 13C cave was reached 15 m long horizontal level on the top of Tri Drticu chimney. On the bottom of Krizuv sinkhole was started up diging and at the end of year 6 m of depth was reached. In the Pikova Dama cave was started up diging as well but any further advance was not reached. Members of Planivy speleogroup held an expedition to Slovenia and Romania to the Sureanu and Bihor (Padis) area.

At July of 2003 year was first time in history partly pumped out sump of Bila Voda creek between 13C and Spirálka cave. In consequence speleodiving discoveries before known passages was measured in 175 m of length. The sump was pumped out into 6m depth. During this action was approved the Bila Voda creek has flowed in the lowest level under actual flood level. Assumed direction of Fousaty sump to Planivy cave was not confirmed.

In the Nova Amaterska cave was continued in research of Labyrith of M. Slechta and eastern braches of Macossky corridor. In one of them were discovered new passages with active river-bed of Bila Voda creek, 180 m long together (more informations in this issue). There was found and documented small horizontal level on the top of 40 m tall chimney in Macossky corridor. In the „13C“ cave was achieved speleodiving research of sump between „13C“ and Spiralka cave in cooperation with speleogroup Speleoaquanaut. All activities of our group and others informations are newly available on internet domain www.planivy.cz. Members realized expedition to Bükk highland in Hungary and someones participated in speleoproject Kanin 2002 in Slovenia.

At the beginning of 2002 was explored left side branch in the Macossky corridor near the Labyrinth of M. Slechta in the Amaterska cave. Main aim was discovery of unknown Bila Voda creek river-bed. After taking out of sediments and cutting thru dripstones narrow passage exhausted into 17 m deep shaft. On the bottom was found active flow of Bila Voda creek. Downstream leads river-bed with a few left-side tributaries and it is finished after 30 m in outlet sump. Upstream continues inflow part 90 m long. At first this is getting over sump lake thru a chimney. From its top further continues freatic canal. This is slowly going down to next part river-bed of Bila Voda creek named Aqualung. Aqualung is predominantly flooded of active stream and is finished by inflow sump. Main direction of this system is same like direction of Macossky corridor but is situated in lower active level. Inflow part communicates with similar part of Amaterska cave – Crematorium – which is distant less then 15 m. From outlet part active stream drains to unknown parts in Solim’s bowl direction (water shaft which is flowed pass thru of Bila voda creek). Connection with the Labyrinth of M. Slechta was not proved. Length of new discoveries is about 180 m.
