If you see Mary Lake on the map at the stream's headwaters, don't think of fishing it. It has no fish. In the northeast section of the park, on the Northeast Entrance Highway. Take the Lamar River Trail or Cache Creek Trail. Underfished even though its confluence with the Lamar lies near the highway.
Anglers can expect to catch bigger rainbow and cutthroat than in many similar-sized streams.
In the northeast section of the park, this diverse stream parallels the Northeast Entrance Highway. Soda Butte Creek has lots of changing characteristics, ranging from a bumpy run in its upper reaches to a wide, meadow stream as it meets up with the Lamar. The rainbows and cutts are above average in size. The brook trout are small but plump. This is a good place to learn how to cast or fly fish.
