The section of the South Branch Penobscot River in Passamaquoddy territory (Hammond Township) in Somerset County has some special regulations. From April 1 through Aug. 15, the daily limit on trout is two fish, with a minimum length of six inches. (Only one may exceed 12 inches.) From Aug. 16 through Sept. 30, the bag limit is one fish, minimum of six inches. Fishing is allowed with artificial lures only.

In Holeb Township, the daily creel limit on brook trout is two fish, with a minimum length of 14 inches.

State rules prohibit the use of motors greater than 10 horsepower on Big Fish Pond and the thoroughfare upstream to Little Fish Pond and Grassy Pond. These waters are limited to fly-fishing only. The daily creel limit on Little Fish and Grassy is two brookies, with a minimum of 10 inches.

Cape Horn Pond in Prentiss Township also has a daily bag limit of two fish, 10-inch minimum length. Fishing (with flies only) is above-average here and well worth the drive up Route 201 to Kelly Dam Road to access the Passamaquoddy territory.

Nearby, Mary Petuche Pond is subject to tribal regulations that will be posted, so call ahead before wetting a line there. Lower Wellman Pond, Hall Pond (flies only), Duncan Pond and the unnamed inlet stream from Hall to Duncan also have a two-fish, 10-inch minimum-size restriction. Wellman and Duncan ponds are open to artificial-lure fishing only.

Sections of all other rivers, brooks and streams in Passamaquoddy Territory in the above townships, as well as in Alder Brook, Pittson Academy, Soldiertown and Hammond Townships, fall under general-law provisions. Many of the Washington County waters fall under the general law, including Lower Chain Lake, the Sysladobsis (lower) lakes, Grassy Pond and sections of prime trout brooks and streams in T5 NDBPP and T19 MDBPP.

The Penobscot Indian Nation also holds some prime trout fishing holes. In Alder Stream Township, Round Mountain Pond opens May 1 to fly-fishing only, with a daily bag of two trout and a 10-inch minimum size restriction.

From the confluence of Alder and Little Alder streams downstream to Penobscot Territory boundary lines, from April 1 through Aug. 15, anglers age 15 and under may use artificial lures with single-pointed hooks. For anglers 16 and older, and all anglers from Aug. 16 through Sept. 30, these waters are open to fly-fishing only, as are the rest of Alder, Little Alder and their tributaries and the North Branch Dead River.

Both Blanchard and Snow Mountain ponds are open to fly-fishing only, and no motors are allowed.
