In the building of the Olimpiyskiy pool, competitions were held in swimming, water polo and diving. Its internals were made strictly according to the Olympic standards. Training and demonstration pools (the size of each is 50x25, depth – 2.2 m), separate swimming pool for jumping (length – 25 m, depth – 6 m). The jumping and swimming sectors were divided by an acoustic glass partition. This made it possible to compete simultaneously in different sectors.
One of the days of the Olympics, a dramatic event occurred when they forgot to lower the partition. In the jumping pool, Alexandr Portnov made another attempt to jump from a 3-meter diving tower. At the same time, swimmer Vladimir Salnikov went for a record on the lane of the swimming pool: the stands roared, everyone was excited (including technical staff), the noise did not allow jumpers to concentrate. Salnikov captured the gold and set a record at the same time: he was the first in the world to swim 1,500 m freestyle in 14 minutes 58.27 seconds. But Portnov also became an Olympic champion. He was allowed to repeat the thwarted attempt, and he improved his result. By the way, the jumper from the GDR was also given a second attempt – he jumped from a 10-meter diving tower also without the partition. It was Falk Hoffman. His extra jump was a gold medal jump in his discipline.
Everyone said that the water in the Olympic pools was special. Even experts called it "fast water". In this water, 12 Olympic records, 49 world records and 42 European records were set.
