A St. George River Pond in Union
Seven Tree Pond covers 528 acres in the towns of Union and Warren, a few miles inland from the busy midcoast harbors. It is a natural widening of the St. George River, the river that flows on south through Warren and Thomaston to reach saltwater. The pond reaches about 45 feet at its deepest, with a mean depth around 24 feet, and its connection to the river system gives it a steady flow and a mix of fish you would expect from moving water and a quiet pond both.
This is one of a cluster of ponds in Union, alongside Round Pond and Crawford Pond, that together make up easy, low-pressure paddling country close to Camden and Rockland. Seven Tree is the most accessible of them, with a state boat launch right where the river enters the pond. The setting is gentle midcoast farmland and woods rather than dramatic wilderness, which makes it an inviting place for an unhurried day on the water.
Lake paddling
Paddling
Seven Tree Pond is excellent flatwater for canoes and kayaks. The pond itself is a manageable size for a relaxed paddle, and the real draw is that you can keep going. From Seven Tree you can paddle up the outlet to reach Round Pond, turning a short outing into a longer connected exploration of the Union ponds. The St. George River connection means there is always a quiet channel to follow.
The shoreline is a gentle mix of woods, fields, and camps, and the water is calm enough most days for easy paddling without the wind worries of a big open lake. Loons, herons, and other waterfowl are common, and the slow current makes for pleasant downstream drifting. This is a good lake for beginners and families looking for a low-key paddle.
Do not stop at Seven Tree. Paddle up the outlet and you can reach Round Pond by canoe, linking the two for a longer, quieter trip. It is one of the better connected-water paddles in the midcoast, and most of it stays sheltered from wind.
Fishing
Seven Tree Pond fishes well for a midcoast pond. Brown trout are stocked and add a cold-water target to the mix, best pursued in spring and fall near the cooler water. Smallmouth and largemouth bass provide the most consistent warm-water action, holding around the rocky structure and weedy coves, with summer being the prime bass season.
White perch and chain pickerel round out the fishery and are easy and fun on light tackle. The pond is also part of the St. George River’s sea-run alewife system, with alewives moving through the connected waters. The water quality runs on the lower side, but the fishing stays productive. Check current Maine regulations before you fish.
The state-owned boat launch is off Route 235, on the left where the St. George River flows into the pond. It is a straightforward ramp with parking and works for trailered boats and hand-carried canoes alike. It is the obvious starting point for both fishing and the paddle up to Round Pond.
Getting There

The state boat launch is off Route 235 where the river enters the pond. Watch for the access on the left coming from the village. Cell service is spotty in this rural stretch, so set your route ahead of time.
