Ta harbor of Riga is mainly formed by the main branch of the ,na River on which the major part of the quays and shipeing tnstallations are located. A smaller harbor is located on a branch of the rifer east of the main stream (Luehlgraben ailgravia Caureka). The fishing harbor is located downstream on 'Vac east bank of the river, and the harbor of Duenamuende (Daugavriva), which the Soviets use as a naval base, is located on the west bank of the river close to its mouth. The harbor installations most of which had been destroyed during the war, have meanwhile been reconstructed except for a small number of buildings and equipment.

(These guard boats generally fly the green flag of the border defense force). Outgoine veeeels are escorted as far as ieben Street, b. 'Ice Conditions C. during the winter, shipping traffic is rather seriously hir , ed because the i;ulf of Riga is frozen over; the aperoach to ',Ilea acpends on the ice conditions prevailing in the Irben Strait which, as a rule, begins to freeze over in Jaeuary and thaws in April. It is, however, eossible to keep sniping going throughout the einter on the ;Arena diver eith the aid of icebreakers. Anchors Suitable anchorages in 14 to 23 meters of water and on good holding ground are found west of the leading buoy, but they offer no shelter frorli northerly winds. Excellent anchorages in 9 meters of water are available inside the jetties on the east side of the river beteeen .egnusholm (:::angalsalas Ciem) and ainusch (Rinssi). d. There are no tides in these isaters, the water level depending only on the direction, of the wind. During the ice-melting peried, the Water level is liable to rise as high as 3 meters above mean water level. ;7a1 a rule, harbor operations are generally net hindered. by weather conditions. 21.1.2-iaba.q Pilotage is compulsory.

The River bed from the mouth of the river to Riga is 8 to 10 meters deep, which depth, however, can only be kept by uninterrupted dredging operations. The Ialalaapayage is about 10,000 meters the quay installations are modern and meet all requirements for ships trading in the Baltic Sea. The totathof the railroad sidings (including the shunting station at the export quay is about 15 kilometers. In addition to the cranes mentioned in connection with the description of the various quays, two 15-ton floating cranes are available in the harbor area. Two towboats are available for towing and other harbor service operations. As far as is known, an icebreaker is also stationed in Riga/ Duenamende; Soviet icebreakers will also ee made available in particularly hard winters (in 1953, for example, icebreaker "Sibiryakov"). No exhaustive information is available on sheds and warehouses; it was not learned whether all buildinae of this kind which were destroyed during the war, have been reerected and put again into operation. It may, however, be safely said that the sheds and storing facilities will assure adequate handling of average transhipment business. 2. .Details (Ea,st bank.), a. liaenuaholm (1): ?

A lateral branch of the river connects it with Stint Lake (9). The ;:seehlraben harbor facilities were considerably imeroved by the expansion of the quays and the "Old :alehlgraben 3hipyard", carried out in the past few years. A modern quay (10), about 1,500 meters long with a depth of 9 meters alongside, and railroad tracks maining along its total length, is located on the southeast side of that branch of the river, which is about two miles long and dredged to 10 meters depth. A mine depot (11) of the 3oviet Navy, separated from the quay only by the railroad tracks, is also located there; a fertilizer plant is located at the northeast end of the eier (12). J railroad and road bridge (13) forms the border between eluehlaraben harbor and Stint Lake in the northeast. Theuehlaralaan_alpayAKLI (14 - Picture 2) is located on.the north side of Luehlgraben harbor. Oaly vessels up to medium size could. formerly be repaired at this yard because of its limited capacity. However, in the past few years, the shipyard installations were considerably improved and expanded toward the northwest, eormitting now the construction of new ships. The shipyard has a quayage of 1,000 meters with 6 meters water alongside, possesses two floating docks capable of accommodating vessels of up to about 4,000 tons and four erficient hammerhead cranes. :aectric current is supplied by the shipyards own steam-driven power plant. The capacity of the new installations seems to indicate that naval vessels can also be built there, although no definite information on this subject has been received. No figures of the shipyard persoeael are available nor could the situation be clarified concerning the arrangement and capacity of the railroad system in the shipyard and its connection with the main railroad network. The shipyard premises are guarded by jeviet soldiars who are accommodated in a barracks installation newly erected within the shipyard area for this purpose. A branch of the euena hiver, the "Red Duena" (Sarkandaugava) (15; runs from Leehleraben basin toward the south; the water in the northern section of this river branch is up to 6 meters deep, and in the southern section 2 to 3 meters deep (raft berthing facilities); no quays or other harbor installations are available on the ")ed auena" A nigh voltage line with masts, GO meters high., coming fro:: the seuth bank (16) cef the huehlgraben harbor, spans the Duena Aver. jaRa 50X1 Declassified in Part - Sanitized Copy Approved for Release @ 50-Yr 2013/07/09: CIA-RDP83-00418R000100030003-0 Declassified in Part - Sanitized Copy Approved for Release @ 50-Yr 2013/07/09: CIA-RDP83-00418R000100030003-0 SLeRnT -7- d. 1 exbor Installations in kUa 50X1 The Riga harbor area begins with the exeort quay (21), located south of the branching point of the Red Duena and the main chaenel, and is followed by the adjoining exeort harbor (51), the teo harbors technically forming a harbor unit (pictures 3, 4, 5, 6). A quayage of 1,960 meters, 6 to 9 meters deep aloneside, with triple-track railroad sidings are available in this harbor unit. Thejort have a total of sixteen Aesel-electric cranes (eine 5-ton cranes, five 10-ton cranes and two 50-ton cranes); a 60-ton crane, Jeanding about 50 meters landward from the export quay, is ooesibly a construction crane. The northern section of the exoort quay forms a large store yard (22), with an adjoining large cold-storage house (25) in the south, and a five-storied warehouse (24), zet a little back. The two buildings were newly erected after the war. A warehouse shed, about 130 meters long (25), and a three-storied shed, about 60 meters long, (26), and some smaller single-floor store sheds followed in the sutheast as a continuation to the export harbor.' All t-ese sheds are comparatively new. A second row of warehouse .sheds (27) was located at the.rear of these sheds. Thus a total of 6 brick sheds are available, and all are in operation. The town-owned Ai?L.a Anior Station (picture 6)(32) is located on the south side of the export harbor. The entire area of the export quays and export harbor is surrounded by a high wire fence. htrance to the town is only through the southern gate. A guard room accommodating a guard unit of several soldiers is to be found in that entrance/exit gate house. ,Indreas ,uay (33), also called the coaling harbor is 630 meters lore; and 7.3 to 9 meters deep alongside; it adjoins the exeort harbor in the south. An eight-storied grain elevator (54 - picture 6), having a storage capacity of 16,000 tons, is at the northern end of the quay. This quay is used as a coal dump, as no sheds are available there. Two railroad tracks (one running close along the quay, and the second about 50 meters landward)from the edge of the quay, and six bridge cranes (one 20-ton crane and five 10-ton cranes) are available for cargo-handling operations. Passenger ships calling at iiieu generally berth alongside the Andreas Pier. Andreas Harbor '35), adjoinin the Andreas ,.uay in the south, is the berthing basin for towboats and harbor service craft. Railroad sidings also run along the east side of this quay. A small shipyard (56) (Suds Remont :dadaskoi Andrea Aevny Gavany), located on the northeast side of Andreas harbor, carries out repairs to ships and machinery. .A 1e0-ton marine railway is available,but there is no dock.
