About this water

Maramec Spring Park is the fourth piece of the Missouri trout-park set and the most useful St Louis-facing park entry. It is privately owned by The James Foundation but operated as a public-use trout park, with Maramec Spring Branch and the Meramec River carrying daily stocked trout through the park season. As with Bennett, the product value is rule clarity: daily tag in the catch-and-keep season, annual trout permit replacing the daily tag in winter catch-and-release, park entry logistics, and a clear distinction between stocked park water and broader Meramec River trout context.
