On 16 September 1976, a trolleybus operating alongside
Yerevan Lake went out of control and fell from the
dam wall into the lake. The sound of this accident was heard by
Shavarsh Karapetyan, a multi-champion
finswimmer, who was training with his brother Kamo, also a finswimmer, by running alongside the lake. The trolleybus lay at the bottom of the reservoir some 25 meters (80 ft) off the shore at a depth of 10 meters (33 ft). Karapetyan swam to it and, under conditions of almost zero visibility due to the
silt rising from the bottom, broke the back window with his legs. The trolleybus was crowded, it carried 92 passengers and Karapetyan knew he had little time, spending some 30 to 35 seconds for each person he saved. Karapetyan managed to rescue 20 people, but the combined effect of cold water and the multiple wounds he received left him lying unconscious for 45 days, with subsequent sepsis (due to the presence of raw sewage in the lake water) and lung complications. ==See also==
