A fact from Eastman tunnel appeared on Wikipedia's Main Page in the Did you know column on 7 August 2007. The text of the entry was as follows:

Did you know... that the 1869 collapse of the 2,500-foot-long Hennepin Island tunnel (pictured) resulted in cementing over the only major waterfall on the Mississippi River?

spillway the correct term?[edit]

The article says this was dug "to create a downstream spillway" but the spillway article says that spillways exist only for flood control of dams. Is what really meant here something different? More like a Power Canal or something similar? 65.210.129.209 13:16, 7 August 2007 (UTC)[reply]

The spillway article is too limited. There are other uses for the term, including bypasses of dams or outlets of a channels used during highwater, and outlet channels carved through natural dams such as moraines. Kablammo 13:33, 7 August 2007 (UTC)[reply]

Something needs fixing then I guess... got any sources that might help with improving the spillway article handy? Thanks. 65.210.129.209 14:20, 16 August 2007 (UTC)[reply]

From the reference "Engineering the Falls: The Corps Role at Saint Anthony Falls" - "excavate a tunnel under Nicollet and Hennepin Islands for their tailrace" and "began excavating the tailrace"
The correct name is "tailrace tunnel"
(unrelated) the Power Canal at the West Bank is a headrace canal. A mill may have a headrace to connect it to the source and a tailrace to channel the water out of the mill turbine. BudKey (talk) 13:13, 22 October 2020 (UTC)[reply]

Hennepin Island tunnel → Eastman tunnel –
The definitive source of the name for this entity is Nomination of the St. Anthony Falls Historic District to be on the National Register of Historic Places The nomination is from the City of Minneapolis to the National Park Service to place the St. Anthony Falls Historic District on the National Register of Historic Places (it was placed there).
It has descriptions of "contributing resources" to the historic district. The tunnel is one of the resources. The tunnel, in this document, pdf page 83, is called the Eastman Tunnel. That is how it is known on the National Registry of Historic Places.

The Corps of Engineers did the final fix of the tunnel disaster. Engineering the Falls: The Corps of Engineers' Role at St. Anthony Falls
The COE calls the disaster the Eastman Tunnel Collapse.
An older archived version of this document, which is one of the article references (Engineering the Falls: The Corps Role at St. Anthony Falls), also says Eastman Tunnel Collapse.

River of History: A Historic Resources Study of the Mississippi National River and Recreation Area by John O. Anfinson, was developed for the National Park Service, and the U.S. Corps of Engineers
It has 2 figures that refer to the Eastman Tunnel and details "after the Eastman tunnel collapsed"

"The Falls of St. Anthony: The Waterfall That Built Minneapolis" (1987) by Lucile M Kane, is published by the Minnesota: Minnesota Historical Society. It is a standard source for the history of the St. Anthony Falls.
This book is also one of the references for the article.
It refers to the eastman tunnel. (pg 69-71, 74, 91)

The Minneapolis Riverfront as the Birth Place and First Place was prepared for the St Anthony Falls Heritage Board
It refers to the Eastman Tunnel

Evaluation of the 1990 St. Anthony Falls Interpretive Plan is a report to the The St. Anthony Falls Heritage Board
It includes recommended "interpretive exhibits" including 2 relating to the Eastman Tunnel

The Minnesota Historical Society - has had many "Events, Programs and Exhibits" in which "Visitors will learn about the Eastman Tunnel Collapse".

Both picture for this article are labeled "...Hennepin Island..." by Wikipedia. That is not in the description from the source of either.

Looking for a source that labels this entity "Hennepin Island tunnel", they appear to be derived from this Wikipedia article. I have not seen anything as reliable as any of the above.

This should include a redirect from Hennepin Island tunnel to Eastman tunnel

I will change "Hennepin Island tunnel" within the article to "Eastman tunnel", including pictures.

I will also change most of the Wikipedia article links from Hennepin Island tunnel to Eastman tunnel

Error[edit]

In the information at the start of Talk: Eastman tunnel is:
"A fact from Eastman tunnel appeared on Wikipedia's Main Page in the Did you know column on 7 August 2007. The text of the entry was as follows:
Did you know... that the 1869 collapse of the 2,500-foot-long Hennepin Island tunnel (pictured) resulted in cementing over the only major waterfall on the Mississippi River?"

That is wrong. It is the Eastman tunnel, not the Hennepin Island tunnel. And the fix for the tunnel disaster was a dike. The (originally wood) apron was the fix for a different problem (upstream progression of the falls). The Corps of Engineers dike was created about the same time as the (second) wood apron, but they fixed different problems. BudKey (talk) 13:53, 17 October 2023 (UTC)[reply]
