Grassrivers is an official Grand Theft Auto VI region in the state of Leonida. Rockstar has included the name in official Leonida materials. WhenGTA6 records the name. It does not write a nature documentary around it.
Compound names invite fan ecology. “Grass” plus “rivers” is still just the official string. This site will not declare a wetland classification, a wildlife list, or a flood mechanic. Those claims need first-party copy or a clearly labeled shown clip — and even then, a clip is not a system description.
Name versus invented landscape
If official screenshots later caption a Grassrivers location, this page will quote the caption. Until then, “it looks swampy in a fan crop” is not a source. The map rule is the same for every region: shown names, no official square miles.
Crossplay, GTA Online for VI at launch, and PC are unannounced product facts. They do not secretly describe Grassrivers. WhenGTA6 will not invent a wildlife list to fill space. The countdown still tracks November 19, not a region unlock.
Basketball in trailer footage and vehicle shops in screenshots are game-wide shown items. They are not Grassrivers amenities unless Rockstar places them there.

Place among the other official regions
Grassrivers sits on the same short list as Vice City, Leonida Keys, Port Gellhorn, Ambrosia, and Mount Kalaga National Park. Fan maps that draw Grassrivers as half the state are not measurements.
Jason Duval and Lucia Caminos are protagonists of the Leonida game. That does not make Grassrivers their hometown. Cal Hampton is not placed here.
How rumors get in — and stay out
A “full political map of Leonida” that adds Grassrivers counties is a rumor document. WhenGTA6 will not merge it into this entry. Process: how rumors are rated.
Weather rumors (including storms) are not attached to Grassrivers here. They are unconfirmed game-wide. The map guide remains the size answer for the whole state: biggest yet, no official square miles.
What WhenGTA6 will not claim
- A swamp, wetland, or wildlife essay
- Official towns, trails, or missions
- Character hometowns
- Weather systems pinned to this name
- That Grassrivers is half the state
- That 60 FPS describes the landscape

This page will quote a caption if Rockstar prints one. Until then the official string is enough.
Read the name as a name. If a thumbnail promises a swamp documentary, that promise is not a Rockstar sentence. Use how rumors are rated for those videos, the map for the official roster, and Leonida for the state container. Preload on November 12 still does not open Grassrivers early.
