On 7 April, the ice on the Moscow River in the vicinity of Moscow began
to drove. By 0500, the ice had reached pavshina, where it jammed and had to
be blasted free.(l) On 8 April, the ice was flowing in small and scattered
pieces. The greater part of the ice had passed by on 7 April. In the next
few days, ice was expected to flow from Zvenigorod and Mozhaysk.
The level of the Moscow River continued to rise slowly. At Mozhaysk
during a 24-hour period or. 6 - 7 April, flood waters caused the river to
rise 4 centimeters; at Zvenigorod, 43 centimeters. In the pavshina region,
a temporary recession was noted.(2)
The ice floe reached the former Bab'yegorodskiy Dam at 1400. Here, dur-
ing a 24-hour period on 6 - 7 April the water level rose 70 centimeters, ex-
ceeding the winter level by 140 centimeters. In the vicinity of Moscow, the
ice mass continued to move until late at night. During the night of 7 April,
the water level dropped slightly. The ice mass was expected to reach the
area around Kolomna by 1400 on 8 April. The flood waters continued rising.
The Karamyshevskiy Dam, which is to admit flood waters into the Moscow
River, was opened on 7 April. During the next few days, the water level of
the Moscow Lake was expected to rise considerably.(1)
Between 5 and 7 April, small quantities of Ladoga ice began to enter the
Neva River from Shlissel'burg Bay. However, the ice melted before it reached
Leningrad. It was expected that blocks of ice would reach the city for the
first time on 8 Aril.
This year, Ladoga ice appeared on the Neva River 8 days before the aver-
age date for past years. The present ice flow is not the main one, however,
since the greater part of Lake Ladoga ice has not yet broken.(3)

Ice movements have also been noticed in the upper parts of the Luga River.
On the Syasi, pashe, Oyati, and other rivers, the ice is still firm (4), but
part of the ice on the Volga River began to move on 7 April and by 8 April the
entire ice mass started moving.(5)
