Osceola Island And Holston River Weir Dam
Nov 2, 2023 07:15:51 #
During my recent trip I visited Osceola Island and Holston River Weir Dam located in Bristol, Tennessee. A weir dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in height of the river level(per Wikipedia). It also produces excellent fishing opportunities. This must be working as I saw a large number of people fly fishing.

Interesting dam design.
But aren't all dams "a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in height of the river level"?

Unlike dams, weirs do not usually prevent downstream fish migration(as water flows over the top and allows fish to bypass the structure in that water)….also per Wikipedia.

Isn't fish migration a different subject/aspect of dams? The definition you used applies to all dams.
And if the water level behind the dam goes below the top of the dam, no water will flow over a weir dam also.

A weir generally allows the water to flow over the crest(which is the top) or sometimes underneath some sections. In comparison, dams mainly allow water flow to be regulated (controlled) by gates or spillways. A dam usually does not allow water to go over the crest.

I suppose it depends solely on the design and purpose for the waterway.
At least six dams near me always have water going over the top.

Good eye! Definitely a great place for catching fish.
