Montana/Waterways
Waterways can be imported from external databases or traced from aerial imagery. In any case please keep in mind that imported or traced waterways need to be merged with existing map data; highway intersections will need waterway sections in culverts or bridges (or fords) added to the highways; nodes for lakes, dams or islands imported from GNIS will have to be merged with the areas traced or imported (best by moving all the gnis:* tags from the node to the area and then deleting the node).
Tracking NHD Imports
Imports from the National Hydrography Dataset are tracked on the NHD wiki pages; Montana is in the central basins area; mostly relevant would be region 10 (Missouri).
The tables below have been created mostly with aerial tracing in mind; if the area in question is already imported from NHD, just use it as a reminder to review the imported data in that area or for that river and mark it as done when you completed the review.
Lakes and Reservoirs
Wikipedia has lists of named lakes and reservoirs by county. These lists are incomplete and contain a few errors, but are a good way to look for lakes that are stilling missing in our map. While you are tracing lakes from aerial photos, look for more lakes and ponds in the area.
Rivers
The rivers in the list are taken from the known incomplete list at Wikipedia, so please add any that you find missing.
