They have been trying to get the Silver salmon population in small coastal streams to increase for quite a while now.

In the 1960s there were good Silver salmon populations in many of our small California coastal streams.

Small dams and dewatering from vineyards, etc. pretty much eliminated over 90% of them.

I knew some old friends of the Greatest Generation who yearly fly fished for them in about a dozen small streams.
