About the Branch Brook
Branch Brook runs through the sandy country behind the southern Maine coast, gathering in the woods and wetlands of Wells and Sanford and running down to the Mousam River a few miles inland from Kennebunk. It is an unremarkable looking stream and it is protected far more carefully than its appearance suggests, because it is the sole source of drinking water for Kennebunk, Kennebunkport and Wells. The Kennebunk, Kennebunkport and Wells Water District owns or controls a large block of the watershed, and that ownership has kept development off the banks and the aquifer intact in a part of Maine where very little land has escaped attention.
The result is a cold, clean, sand and gravel stream carrying wild brook trout within a short drive of one of the busiest stretches of tourist coast in New England. The trout are not large, as is usually the case in coastal sand plain streams, but they are wild and they are distributed throughout the system rather than concentrated in a few holes. Brown trout are present in the lower reaches, chain pickerel and largemouth bass occupy the slower dead water and the beaver flowages, and American eel are common throughout and still have reasonable access from the sea.
The gauge reports discharge and stage and sits on one of the better studied small coastal streams in Maine, because the water district and the United States Geological Survey have a long standing interest in how much the aquifer can yield without harming the stream. That makes the flow record unusually useful for an angler: Branch Brook is small enough to be affected quickly by dry spells, and the summer low flow reading is a direct indication of whether the trout have retreated into the few deep and spring influenced pockets or are still spread through the riffles.

Seasons
Spring: high clean flows and the most active trout fishing of the year through the riffles and runs.
Summer: the stream drops and warms, and the trout concentrate into the spring influenced pockets and shaded bends.
Fall: flows recover with the autumn rain and the brook trout colour up and feed hard before spawning.
Winter: cold and largely iced over, with the season closed on most of the stream and very little activity.
