Rivers a.nd Artificial Watercourses The Y4 _W0renai)8 At tale village of liotoshtno, there is the artificial upper Volga dam ((Verkhnyi.Volzhskii J3iishlot). With the waters of the lakes above (Malyi and. olshoi Verkhit. Sterzh, Veeluga, ara~: Peno), the dam forms the reservoir which enables the Volga to carry traffic from Rzh:tav to Ryoinsk, The dam collects about 350 million cubic meters of reserve water. Small ateuaers ply up and down the Selizh!arovkP_ river and. on Lake Seliger; the latter is eighty ksne. long; and is, in planes, twenty to teentymfive meters deep. `.:`here are thirty-two small ran ids between ;}ieish of and Rzhev, and six between Rzhev. and Kalinin. The largest rapids is the Tienski,, which lies between 4;heltsy and Jtzhev. (b) Traffic on ?theVolgas. '?eg-ulr,.r steansn.n traffic on the Volga begins at Rzhev~ The distance from this point to Kalinin is 179 Iona.; the jol.-n-ney requires fifteen ars downstre and twenty-four for return. Vessels eta?rs at nine jetties on the way. The steamers on this route have single decks. : teamerg plying between Kalinin and Rybinsk are a little larger; some are of American design, with two decks. The dovmstream journey requires thirty-one hours and the return journey forty-four. Steamers on this winding; route, which is 390 lens, long, are somewhat hindered by rocks and shoali, and in most cases traffic is interrupted from the second ;.a1f of July to the beginning of septenber because the upper Volga .am is unable to sunnly sufficient rater to the upper Volga during the low water ueriod of the eumraer.
