Talk:List of longest rivers of Mexico

Map
I believe the map is mostly complete, except that some of the river lengths seem kind of off. The Fuerte River seems to be a lot longer than the Cualicán River. Additionally, I couldn't find out where the Aguanaval River joins the Nazas, so I'm assuming it was a mistake and they are actually separate rivers (might have to be fixed). Lastly the San Juan and Salado Rivers, both tributaries of the Rio Grande, appear long enough to be on this list, at least according to the map, though neither of their articles have length figures.

 * Map looks good, a big improvement to the article. I think you are right that the Nazas and Aguanaval don't actually meet. They appear to drain into large basin that has no outlet to the sea. I don't have the impression that the basin is a lake. Since I relied so heavily on a single government source (Statistics on Water in Mexico), I didn't have many cross-checks. The Conchos isn't on the government list, for example, which seems puzzling. Your hunch that others like the San Juan and Salado might be long enough is probably a good one. Alas, the individual articles on rivers of Mexico often give no lengths, and even when they do, they don't provide sources. Maybe or another of the river wizards will know of other reliable sources. I wonder if Mexico has a GIS system like the NHD that might have more data. Anyway, thanks for doing the map. Finetooth (talk) 22:34, 11 July 2011 (UTC)


 * I'll update the map when needed, just give me a heads up with any changes. (P.S. I like how you say "river wizards")... Shannon  +    º    !   06:25, 13 July 2011 (UTC)


 * Thanks, will do. I count you among the river wizards, by the way. Finetooth (talk) 16:07, 13 July 2011 (UTC)


 * Starting to look for good info on rivers of Mexico--an NHD-like source would be great, not sure one exists, at least online, but perhaps there's a detailed GIS dataset out there--only just started looking, found this: http://wikien4.appspot.com/wiki/List_of_longest_rivers_of_Mexico ...very odd.

 * This web map app looks potentially promising, http://gaia.inegi.org.mx/mdm5/viewer.html. If only my grasp of Spanish was better. Pfly (talk) 20:08, 13 July 2011 (UTC)
