Code of Maine Rules › 01 - DEPARTMENT OF AGRICULTURE, CONSERVATION AND FORESTRY › 669 - BUREAU OF FORESTRY (MAINE FOREST SERVICE) › Chapter 25 - STANDARDS FOR PLACING WOOD INTO STREAM CHANNELS TO ENHANCE COLD WATER FISHERIES HABITAT › Section 669-25-3 - DEFINITIONS

Current through 2024-29, July 17, 2024
For the purpose this rule, the following terms are defined
				  as follows.
A.
Atlantic salmon
				Areas:
From the Androscoggin River northward along the Maine coast to
				the Dennys River, and wherever these fish occur in the estuarine and marine
				environment. The following impassable falls delimit the upstream extent of the
				freshwater range: Rumford Falls in the town of Rumford on the Androscoggin
				River; Snow Falls in the town of West Paris on the Little Androscoggin River;
				Grand Falls in Township 3 Range 4 BKP WKR, on the Dead River in the Kennebec
				Basin; the un-named falls (impounded by Indian Pond Dam) immediately above the
				Kennebec River Gorge in the town of Indian Stream Township on the Kennebec
				River; Big Niagara Falls on Nesowadnehunk Stream in Township 3 Range 10 WELS in
				the Penobscot Basin; Grand Pitch on Webster Brook in Trout Brook Township in
				the Penobscot Basin; and Grand Falls on the Passadumkeag River in Grand Falls
				Township in the Penobscot Basin.
B.
Bankfull Elevation:
The elevation of the stream banks at bankfull
				width.
C.
Bankfull Width:
Bankfull width is the width of the stream at the "Normal high water
				line" as defined in 38 MRSA §480-B.(6) to mean "that line along the shore
				of a great pond, river, stream, brook or other nontidal body of water which is
				apparent from visible markings, changes in the character of soils due to
				prolonged action of the water or from changes in vegetation and which
				distinguishes between predominantly aquatic and predominantly terrestrial
				land..."
D.
Biologist:
A fisheries biologist employed by the Maine Department of
				Inland Fisheries and Wildlife or Maine Department of Marine Resources, or other
				qualified person identified by those departments, who has attended a training
				in wood addition techniques including an introduction to timber harvesting
				techniques and forestry regulation.
E.
Designated Reach:
A section
				of stream that has been identified by DIFW or DMR as suitable for wood addition
				treatment and where a DIFW or DMR biologist or their designee has developed a
				treatment plan that has been mutually agreed upon by DMR or DIFW, and the
				landowner or their agent. The treatment detailed in the plan must be consistent
				with the standards in this rule.
F.
Dispersal Flow:
Stream flow forced around a piece of large wood
				and into the stream banks leading to bank erosion.
G.
Key Piece:
A piece of wood
				that will form the basis of a log jam structure and is of sufficient size to
				resist movement by bankfull flows.
H.
Licensed Forester:
Licensed
				forester means a forester licensed under 32 MRSA, chapter 76.
I.
Meander:
A meander is one of
				a series of freely developing sinuous curves or loops produced as the stream
				moves from side to side of its floodplain.
J.
Meander bend
: A meander bend
				is the convex side of a meander.
K.
Stream channel:
Stream channelmeans a channel between defined
				banks created by the action of surface water, which is characterized by the
				lack of terrestrial vegetation or by the presence of a bed, devoid of topsoil,
				containing waterborne deposits or exposed soil parent material or bedrock; and
				which is connected hydrologically with other water bodies. "Stream channel"
				does not include rills or gullies forming because of accelerated erosion in
				disturbed soils where the natural vegetative cover has been removed by human
				activity.
L.
Wood:
Wood refers to the stems and branches of trees either fully severed or
				partially attached to the stump. Wood may include uprooted trees if the root
				wad or disturbed soil is not in a position such that it will end up below the
				normal high water line. Wood does not include processed wood such as slabs,
				edgings, lumber or timbers, or logging debris including slash and material left
				from temporary stream crossings such as pole or brush fords, or other forest
				product refuse prohibited by 38 MRSA §417 (1).
M.
Wood Diameter:
Wood diameter
				is the average diameter of the stem measured at the large end.
