Left tributaries of the Prokhodnaya River.
For 10.6 kilometers after the source, the Prokhodnaya river receives two insignificant nameless tributaries on the left.
Morenaya river.
10.6 kilometers after the source of the Prokhodnaya River, on the left, a small tributary flows into the river - the Morenaya River, 2.5 kilometers long. The river originates from underground streams of the ancient moraine, which is a continuation of the Kargalinsky Right glacier.
The lower part of the moraine is located between the peaks of Pyla in the south, 3790 meters above sea level and Vechernaya in the north, 3410 meters above sea level. The mouth of the Morenaia River is located north of the Terra glade, at an altitude of 2543 meters above sea level.

Burkitta River.
Through 950 meters after the confluence of the Morenaia River, the Prokhodnaya River receives a tributary of Burkitta, 3 kilometers long. The river originates from the eastern side of Kargalinsky peak 3675 meters above sea level and glaciers on the slope of the eastern exposure of the Prokhodny gorge.

Northern Burkitta River.
560 meters after the confluence of the Burkitta River, the Prokhodnaya River flows into the Burkitta Severnaya River, 2.5 kilometers long. The sources of the river begin from the northeastern side of Kargalinsky peak, 3674.9 meters above sea level.

Sakhnovka river.
1.5 kilometers after the confluence of the Severnaya Burkitta River, the waters of the Sakhnovka River, 2.6 kilometers long, flow into Prokhodnaya. The left tributary of the Sakhnovka begins from the eastern side of the watershed ridge between the rivers Kargalinka and Prokhodnaya. The northern tributary of the Sakhnovka originates from the eastern side of an unnamed peak 2932 meters above sea level. The mouth of the Sakhnovka into the Prokhodnaya River lies at an altitude of 2005 meters above sea level.

Kaskabas river.
3.9 kilometers after the Sakhnovka River, on the left, Prokhodnaya receives the Kaskabas tributary, 3.9 kilometers long. The origins of Kaskabas begin in the northwestern part the Maybulak tract. The mouth of the Kaskabas is located at an altitude of 1527 meters above sea level.

Right tributaries of the Prokhodnaya River.
Karniznaya river.
After 8.6 kilometers from the headwaters of the Prokhodnaya River, the Karniznaya tributary, 2.7 kilometers long, flows into the river on the right. The tributary originates from the eastern side of the Almatynin Alagir ridge from a moraine, flowing lake located on the eastern side of the Almatynin Alagir ridge on a moraine, at an altitude of 3510 meters above sea level, in the northern part of the Karniznaya glacier.
The length of the lake from south to north is 98 meters, the greatest width in the southern part of the lake is 70 meters. The mouth of the Karniznaya River is located at an altitude of 2883 meters above sea level.

For 800 meters from the mouth and above, the stream has a wide channel formed by periodic catastrophic mudflows descending along the stream canyon. Mudflows are formed due to the high steepness of the western slope.

A nameless stream with a small waterfall, located 200 meters south of the bath in the Passage Gorge.
2 kilometers after the confluence of the Bolshoi Iguzek stream into the Prokhodnaya river, a 2.8-kilometer stream flows into the right. Not far from the mouth, just above the path on the stream, there is a small waterfall. The sources of the stream are located at an altitude of 2856 meters above sea level from the springs, in the upper reaches of the western slope of the Prokhodnoye gorge, the mouth of the stream is at an altitude of 1833 meters above sea level.
