L<strong>at</strong>e afternoon. Lecture on fish. There are 4-5 popul<strong>at</strong>ions of omul, occupying various niches.<br />

(1) shallow w<strong>at</strong>er, near the shore<br />

(2) down to 200 meters in the main lake<br />

(3) another popul<strong>at</strong>ion below 200 meters<br />

(4) a steep vertical slope zone.<br />

These popul<strong>at</strong>ions spawn in different rivers, the Selenga is a main one.<br />

We were unable to go ashore in the Selenga Delta, because the lake level is low, and the w<strong>at</strong>er<br />

level where we planned to go is less than a meter.<br />

The delta was seen from some distance off, yet looking like a vast expanse of brown grass, the new<br />

season's green having not yet overtopped the last years. But with binoculars you could see the<br />

green lower down.<br />

There is a lighthouse on an artificial island.<br />

The marsh area is about 7 km. wide with aqu<strong>at</strong>ic grass, and no solid ground.<br />

Visit to Posol'skoye, village.<br />

Here is where a large region of delta sank below lake level in 1861, 190 sq. km. including several<br />

villages, but no one was killed. There was subsidence over a few hours.<br />

Farewell dinner, 11.00 p.m.<br />
