River Mill Hydroelectric Project, also known as River Mill Dam and Station M, is a hydroelectric dam and powerhouse in Clackamas County, Oregon, United States. It is just north of Estacada, Oregon on the Clackamas River at river mile 23.5.

The project was nominated in 2001 to be listed on the National Register of Historic Places. It is possible that it was listed, or that it was deemed to be eligible but not listed due to owner objection.[3] The National Register announced its listing, however, without qualification.[2]

The project is listed in the Oregon Historic Sites Database of the Oregon State Historic Preservation Office.[4]

It is operated by Portland General Electric.[5]

However, these sites, including this one (an unofficial mirror site of NRIS), fail to note the NRIS code DR, which can be seen at another private site. DR is believed to indicate owner objection to the listing, so it appears the site was deemed eligible except for owner agreement.
