This may not apply where you live. But I was reinforcing the walls of a stream for a client who lived on a steep hill and during the construction we dug out a couple of flat spots with water falls to slow the flow of water.

In these flat spots in the steam, which the spring sprung right behind his house, not 200 feet up the hill had started to show up with hundreds of what we call million fish.

So depending on your climate and the habitat around you it is entirely possible.

look for fish in the stream

If you live in a developed country there may be environmental and zoning laws that dictate what you can and can't do with the stream. wetlands and water sources tend to be heavily legislated because so many douchebags of yore would dredge, pollute, dam, divert, or hog them and it would cause a chain reaction of damage to an expansive amount of the local ecosystem and water supply.

for this reason there are building and construction codes involving disturbance and proximity to streams, agricultural and storage codes involving streams, disruption of water flow involving streams, and hell - a lot of places you can't even collect rainwater within proximity to streams because you're effectively "stealing" it from the stream's ecosystem

so... check with your local bylaws OP
