Forest Grove was once a small, scenic town overlooking the Charles River. Now it's a fetid marsh, due to the nonfunctional river lock and the failure of riverside floodwalls. This combination has driven off all but the most inquisitive or reckless scavengers. The dam is home to a small scavenger camp, where transients occasionally stop for the night.
Half of the town is flooded with irradiated water and inhabited by feral ghouls. Mutated ferns are known to grow at Forest Grove marsh and are sought for radiation resisting properties. A small crew recently set up walkways all over the town to cultivate and harvest the ferns for Solomon in Diamond City, but they were all killed when their activities inadvertently attracted ferals. Opening the pub's door near the water on the side of town activates a frag mine.
There is a collapsed, two-story gunshop near the northwest corner of the town. It can be identified by the flashing red light and tall antenna on the roof of the building. On the second floor of the shop are a weapons workbench and duffle bag. On top of the roof are a steamer trunk, two sleeping bags, supplies, and Sheila's holotape.
- Sheila's holotape - On the roof of the gun shop.
- At least 20 mutated fern flowers as mentioned in Sheila's holotape (most of which are scattered across the rooftops). Two flowers are on the ground, between two houses south of the gunshop.
- Botany Class: Mentioned by Sheila's holotape, to obtain mutated fern flowers.
Forest Grove marsh appears only in Fallout 4.
Behind the scenes
Forest Grove marsh is based on the real world location of Forest Grove Park in Waltham, Massachusetts.
- Fallout 4 Vault Dweller's Survival Guide Collector's Edition pp. 314-315: "[3.17] FOREST GROVE MARSH
Forest Grove Marsh is a series of residential and other small buildings that have sunken and been flooded by the river. Some radioactive leak below the area has irradiated the water, and though scavengers have tried to put up walkways across the rooftops of the buildings to explore the houses, the numerous Ghouls in the area have stopped all but the most inquisitive or reckless scavengers. Proceed at your own risk. With the river waters rising to the south, the nonfunctioning river lock is at the root of the problems Forest Grove Marsh is experiencing. There’s little you can do about it, save scavenging some health from the moored boat within the lock. The metal shack has an armor workbench to tinker on. A small scavenger camp with a cooking station, this is occasionally used by scavengers and others passing through. The only permanent resident is a large stuffed space monkey."
