I am using a few resources that make this project possible.
In this project I am doing this by hand with no use of bot edits.
To start off a changeset I first download data from Overpass turbo via JOSM. I use the query:
I next select the objects that I will edit in that changeset and add them to the todo list via the TODO List plugin.
I finally cycle through the list of all the nodes/areas/relations manually and add appropriate tagging for each feature.
In the above step I first position the node/area/relation correctly. Many of the nodes with landuse=reservoir are imported from USGS GNIS and do not have correct positioning. I find positioning by first looking at Bing. If the imagery is bad I use Mapbox Satellite which has similar quality. If there is no obvious reservoir within close proximity of the node I check US Topo Maps for the possible location of the reservoir. If I still do not find the reservoir I look up its USGS GNIS code using the query feature. If I do not find a valid code I delete the node. If I find a valid node I see if it matches up with the node on OSM. I then check the coordinates of where it claims the reservoir is. If the location is not correct I remove landuse=reservoir from the node and move on.

Below will be an unordered bulleted list of all the changeset links that have been a part of this project.
