This paper is cited by a paper I have an interest in. I am adding its references into Wikidata (this is its Scholia) and I added the "Dam-site selection" paper to make a complete reference. The result is something like this.
The PDF of the paper is available for download and as is to be expected, the Way Back machine of the Internet Archive has a copy as well for the URL of the download page. And then there is Internet Archive's Fatcat.
"Fatcat is a versioned, publicly-editable catalog of research publications: journal articles, conference proceedings, pre-prints, blog posts, and so forth. The goal is to improve the state of preservation and access to these works by providing a manifest of full-text content versions and locations."
