| Ok but the first generation to hit the dam died there and had no offspring. Any salmon spawning in these streams have no connection to pre-dam salmon. |

| Right. But their genes do. You assume: hit the dam > died. |

| ▲ | mulmen 4 days ago | parent [-] | | Yeah pretty much. That’s why the dams were breached. | | |
| ▲ | jimnotgym 4 days ago | parent | next [-] | | No it isn't. The remaining salmon population spawned below the first dam because their habitat was cut off. This reduced spawning and juvenile habitat meant less salmon. Now they have the whole river they are spreading out and the numbers can increase again | |
