rock covered 1 foot was reported in the marina entrance in about 44°09′11.3′′N., 77°22′32.5"W. Mariners should favor the E side of the entrance. In 1978, the W part of the basin had depths of 10 feet. Marinas in the basin on the E side of Victoria Park and on the W side of the river provide berths with electricity, gasoline, diesel fuel, water, ice, marine supplies, sewage pump-out, a 20-ton marine railway, and hull and engine repairs.

(530) Just W of the mouth of the Moira River, a fixed highway bridge with a clearance of 74 feet, crosses the Bay of Quinte between Zwick Island on the N shore and Hennessy Point on the S shore. In September 1985, it was reported that much of the remains of a former bridge and causeway are W of the fixed bridge; mariners are advised to use the marked channel.

(531) Chart *2069.-From Hennessy Point, the Bay of Quinte extends SW for 6 miles to Makatewis Island. This stretch has depths of 13 to 18 feet at midchannel except for a few offlying dangers. Anderson Shoal, with a depth of 4 feet, is marked on the N side by a buoy 2.3 miles SW of the Bay Bridge. Two unmarked shoals of 11 and 12 feet are off the S shore of the bay 1.4 and 1.8 miles SW of Anderson Shoal, respectively.

(532) Makatewis Island is off the N shore of the bay 6 miles SW of the Bay Bridge. Narrows Shoal, with a rock that uncovers 3 feet and with depths of 5 to 12 feet, extends SW from the island almost completely across the bay to Pine Point on the S shore. The Narrows is the channel between Narrows Shoal and Pine Point. It is well marked and had a reported controlling depth of 12 feet in 1972.

(533) Charts *2069, *2031.-From The Narrows to its head, the Bay of Quinte is generally shallow with several dangers. A small 8-foot shoal is 0.6 mile WSW of Way Point on the S side of the bay. About 1.8 miles SW of Way Point, Indian Island Bank is a narrow shoal lying E and W between Onderdonk Point and Indian Island. The grassy shoal has depths of 1 to 6 feet and is marked on the E end by a lighted buoy. A 7-foot spot is 0.4 mile NNW of Onderdonk Point. A channel with a least depth of about 7 feet leads along the S shore of the bay from The Narrows to the entrance to the Murray Canal, which connects with Presqu'ile Bay to the W.

(534) On the N shore of the bay, a causeway connects Baker Island and Meyers Point. NE of Baker Island a buoyed channel with a depth of 5 feet leads to a rescue launch wharf on the E side of Meyers Point.

(535) The town of Trenton, Ont., is on the NW side near the head of the bay at the mouth of the Trent River. It is the E terminus of the Trent-Severn Waterway.

opposite the Government wharf has depths of 8 to 9 feet alongside. In 1972, this wharf was reported to be in ruins.

(540) Small-craft facilities.-Berths, electricity, gasoline, diesel fuel, water, ice, sewage pump-out, a launching ramp, and hull and engine repairs are available.

(541) A Rescue Coordination Center is at the Canadian Forces base at Trenton. It is the headquarters of a coordinated network of agencies trained to search for and aid vessels in distress. The Canadian Coast Guard maintains a continuous watch at this center. Requests for assistance from vessels in Canadian waters should be directed to this center by telephone, 613-392-2811, extension 3870 or 3875, or via the nearest Canadian Coast Guard radio station, or by other available means. In U.S. waters, search and rescue facilities and activities are provided and controlled by the U.S. Coast Guard.

(542) Charts *2015, *2021-*2026, *2028, *2029.-The TrentSevern Waterway connects Trenton on the Bay of Quinte with Port Severn on Georgian Bay by a series of well-marked navigable rivers, lakes, and canals about 240 miles long. From Trenton, the waterway ascends 598 feet through 33 locks to Balsam Lake, then descends 264 feet through 9 locks and a marine railway to Georgian Bay. It follows the Trent River, Rice Lake, the Otenabee River, and the Kawartha Lakes to Balsam Lake at the summit, and then descends through lakes, rivers, and canals including Lake Simcoe, Lake Couchiching, and the Severn River to Georgian Bay.

(543) The controlling depth in the waterway is 61⁄2 feet from Trenton for 90 miles to Peterborough, thence 6 feet for 143 miles from Peterborough to Big Chute. At Big Chute, a power station and its dams block the waterway. Two marine railways serve to lift vessels 57 feet across a narrow neck of land to the pool above the power station. The largest railway limits drafts to 6 feet and can handle 100-ton vessels up to 100 feet long and 24 feet wide. From Big Chute for the remaining 8 miles to Georgian Bay the controlling depth is 6 feet.

(544) From Trenton to Big Chute, the locks have a useable width of 32.5 feet and a useable length of 110 feet for square-built scows and 127 feet for standard-built vessels not exceeding a 21-foot beam. From Big Chute to Georgian Bay, the locks have a useable width of 25 feet.

(545) The minimum vertical clearance of bridges and cables over the waterway is 22 feet at normal pool levels. The least recorded clearance during high water stages is 15 feet.

(546) Numerous branch channels diverge from the waterway through the lake section. The depths in these channels vary. The most important branch is the Scugog Branch which connects the S end of Sturgeon Lake, 148 miles from Trenton, with Port Perry, 35 miles S, via the Scugog River and Lake Scugog. The controlling depth in this branch is 4 feet. A lock in the Scugog River has a useable length of 120 feet and width of 33 feet with 6 feet over the sills. The minimum vertical clearance under bridges and cables in the river is 10 feet with a least recorded clearance during high water stages of 8 feet.

(547) Regulations.-Canal regulations and other waterwayrelated information may be obtained from the Superintendent, Parks Canada, Ashburnham Drive, P.O. Box 567, Peterborough, Ont. K9J 6Z6. Mariners are required to have a copy of the regulations on board at all times. A speed limit of 6 mph (5.2 knots) is enforced in all sections of the waterway less than 150 feet wide. Speed limits in other sections of the waterway are designated by

signs attached to white buoys along the channel edge or to signposts along the shoreline.

The islands are near the N edge of an extensive shoal bank that extends 1.5 miles N and 2 miles E from the NE end of Amherst Island. The bank has depths as little as 2 feet and numerous submerged rocks. Salmon Island, 2 miles ESE of Centre Brother Island, is on the NE edge of the bank. A lighted buoy 0.8 mile SE of Salmon Island marks the SE extent of the shoal bank. The N extent is marked by buoys NNE and NW of

Salmon Island and by lights on Centre Brother Island and the W Brother Island. Vessels are cautioned to not pass S or W of Salmon Island.

(558) The SE shore of Amherst Island from its E end SW to Emeric Point (44°06.2′N., 76°42.2 W.) has no landing places, and shallow water extends as much as 0.7 mile offshore. There are several detached offlying dangers along this stretch. An unmarked 30-foot spot is 3 miles NE of Emeric Point, a shoal with a least depth of 24 feet and marked on its SE side by a lighted buoy is about 2.5 miles E of the point; an unmarked 27-foot shoal is 2.2 miles SE of the point. Big Bar Shoal, with a least depth of 9 feet and unmarked, is about 3 miles SSW of Emeric Point.

(559) The S shore of Amherst Island from Emeric Point W to Pig Point is indented by several shallow bays, and shallow water extends about 1.5 miles offshore. Long Point Bay is on the W side of Emeric Point. Nut Island, 1 mile W of Emeric Point, is connected to Amherst Island by a drying bar and separates Long Point Bay and Amherst Bay. Wemps Bay is about 2 miles W of Amherst Bay. Grape Island is off the E entrance point to the bay. A lighted buoy, 2 miles S of Grape Island, marks the W end of a 24-foot shoal. Bluff Point is the W entrance point to Wemps Bay. Deep water is close to the shoreline between Bluff Point and Pig Point 0.8 mile NW.

(560) From Collins Bay at the E end of North Channel eastward to the entrance to the St. Lawrence River, the mainland shoreline is a series of small bays. Horsey Bay has two indentations that provide little protection except from N winds. A buoy marks shoals extending 0.4 mile off Everett Point, on the E side of Horsey Bay.

(561) Charts *2005, 14768.-Cataraqui Bay, with depths of 4 to 13 feet, is 1.7 miles E of Everett Point on the N side of the entrance to the St. Lawrence River. The bay is between Carruthers Point on the W and Samson Point on the E. A breakwater extends E from Carruthers Point across the mouth of the bay to protect facilities on the NE side of the bay. A lighted buoy off the E end of the breakwater marks the W side of a dredged channel that leads to the facilities. The channel has a controlling depth of about 22 feet and is marked by buoys. Small craft have good shelter in the bay in depths of 8 feet. It is reported that rock patches make the holding ground uncertain.

(562) The Canadian Steamship Lines elevator wharf extends from the NE shore of Cataraqui Bay. The E side of the wharf is 642 feet long with a depth alongside of 24 feet in 1979. Two traveling marine towers unload vessels at a rate of 35,000 bushels per hour to a 22-million-bushel elevator. In 1969, the W side of the wharf had depths of 18 to 19 feet alongside. To the E of the elevator wharf, a 17-foot channel has been dredged to the W side of the James Richardson wharf.

General description.-Lake Erie is the southeasternmost and fourth largest of the five Great Lakes. With a greatest depth of 210 feet, it is the shallowest of the lakes and the only one with a floor above sea level. The deepest part of the lake is generally at the E end, while the island region in the W part of the lake is the most shallow. The lake has an average depth of 62 feet. The lake is fed at the NW end by water from Lake Huron via St. Clair River, Lake St. Clair, and Detroit River. The only natural outlet of the lake is at the NE end through Niagara River. Welland Canal bypasses the falls and rapids of Niagara River and provides a navigable connection to Lake Ontario.

(9) The waters of Lake Erie E of Long Point are part of the St. Lawrence Seaway and are under the navigational control of the Saint Lawrence Seaway Development Corporation, a corporate agency of the United States, and the St. Lawrence Seaway Authority of Canada. These agencies issue joint regulations covering vessels and persons using the Seaway. The regulations are codified in 33 CFR 401, and are also contained in the Seaway Handbook, published jointly by the agencies. A copy of the regulations is required to be kept on board every vessel transiting the Seaway. A schedule of the Seaway tolls is contained in the handbook. (See St. Lawrence Seaway, chapter 3, and 33 CFR 401, chapter 2.)

(10) Extensive waterborne commerce is carried out between the ports on the lake as well as to and from the other lakes. The bulk of commerce on the lake radiates from the mouth of Detroit River to the various ports on the lake, to the Niagara River, and to Welland Canal. Most of the vessel traffic proceeds from the Detroit River through the N part of the island region and Pelee Passage. This is the most important channel of the lake. Vessels plying between Lake Erie and Lake Ontario are restricted in size by the locks in the Welland Canal; the maximum vessel dimensions are 730 feet overall length, 76 feet extreme breadth, and 26 feet draft.

regarding pilot requirements to the pilot dispatch centers, marine weather broadcasts, and information on vessel location to all interested parties. St. Catharines traffic control center controls traffic in Sector 7 through "Seaway Long Point," VHF-FM channel 11.

(12) Calling-in point.-Upbound and downbound vessels shall contact "Seaway Long Point" on VHF-FM channel 11 when approximately abeam of the E end of Long Point, Ont. After initial contact, downbound vessels shall guard VHF-FM channel 16.

(13) Complete information on the traffic control sectors and their respective calling-in points is contained in the Seaway Handbook.

(14)

Vessel Traffic Service.-The Canadian Coast Guard operates a Vessel Traffic Service in Canadian waters from Long Point in Lake Erie through the Detroit and St. Clair Rivers to De Tour Reef Light in Lake Huron. (See chapter 3 and the Annual Edition of Canadian Notices to Mariners for complete information.) (15) Fluctuations of water level.-The normal elevation of the lake surface varies irregularly from year to year. During the course of each year, the surface is subject to a consistent seasonal rise and fall, the lowest stages prevailing during the winter and the highest during the summer.

(16) In addition to the normal seasonal fluctuations, oscillations of irregular amount and duration are also produced by storms. Winds and barometric pressure changes that accompany squalls can produce fluctuations that last from a few minutes to a few hours. At other times, strong winds of sustained speed and direction can produce fluctuations that last a few hours or a day. These winds drive forward a greater volume of surface water than can be carried off by the lower return currents, thus raising the water level on the lee shore and lowering it on the windward shore. This type of fluctuation has a very pronounced effect on Lake Erie, because it is the shallowest of the Great Lakes and affords the least opportunity for the impelled upper water to return through lower return currents beneath the depth disturbed by storms. As a result, the water level in the harbors, particularly those at the ends of the lake, fluctuates markedly under the influence of the winds; the amount of fluctuation depends on the direction, strength, and duration of the wind. Fluctuations as great as 10 feet and lasting as long as 12 hours have been observed. September through April is the most likely period, particularly November, December, and January. At the E end of the lake, W winds pile up water in Buffalo Harbor and increase the depth in Niagara River, while E winds drive the water out of Buffalo Harbor and decrease the flow and depths in Niaraga River. The winds produce exactly the opposite effect at the W end of the lake; the greatest effects are at Sandusky, Toledo, and the mouth of Detroit River. Intermediate points are not subject to level changes as great as those at the ends of the lake. Along the S shore, fluctuations caused by winds are generally less than 1 foot above or below normal; extreme fluctuations of about 2 feet above or below normal may occur.

(18)

Weather.-Strong winds are mostly likely in autumn during the navigation season; November and December are the worst as gales blow 6 to 9 percent of the time. However, Lake Erie's maximum wind occurred in July, NNW at 87 knots. Reported by two vessels, these winds were triggered by an Independence Day (1969) squall line. Gales, however, are encountered less than 1 percent of the time from May through September. Summer winds blow mainly out of the S through W, particularly SW. These directions are also favored during other seasons along with northwesterlies and northeasterlies.

(19) The shallowness and orientation of Lake Erie make it susceptible to SW and NE winds, which can quickly raise dangerous seas and, if persistent, create a dangerous surge problem at both ends of the lake. Rough seas are most frequent in autumn and in the E half of the lake. Waves of 10 feet or more can be expected up to 3 percent of the time in the E, while seas of 5 feet or more are encountered 30 percent of the time lakewide; extremes of 15 to 20 feet have been encountered.

(20) Poor visibility is mainly a spring and autumn navigational problem. Over open waters, spring is the most prevalent fog season. Visibilities of less than 0.5 mile occur up to 5 percent of the time. Visibilities of 2 miles or less occur 5 to 10 percent of the time during most of the navigation season. The shoreline is susceptible to both autumn radiation fogs and early spring advection fogs. Fog is more frequent along the N shore.

(21)

Simcoe's visibilities drop to less than 0.5 mile on an average of 46 days annually compared to a range of 15 to 23 days along the S shore. At Simcoe this includes about 4 to 6 days of fog per month in autumn and early spring, about twice as many days as Buffalo, Erie, or Toledo.

(22) Thunderstorms are responsible for some of the strongest winds on the lake. They are generally a problem from April through September, but can occur at any time. Over the open lake, they occur 1 to 3 percent of the time with a peak during the summer months. They are most likely between sunset and sunrise. Onshore they most often occur during the late afternoon, on 25 to 30 days annually. During June, July, and August, they blow on 5 to 10 days per month.

(23)

Ice.-The W end of Lake Erie is very shallow and freezes rapidly, the time of occurrence depending heavily on the temperatures. The ice attains an average thickness of 7 inches and an average maximum thickness of 11 inches. In Maumee Bay, the ice forms a solid sheet about 12 to 18 inches thick. The track through the channel to Toledo remains open except for a 3-foot thickness of brash ice, a slush ice under the refrozen surface. In South Passage, the ice reaches a thickness of about 18 inches because of slight rafting and ridging. During severe winters, thicknesses to 24 inches and windrows 5 feet high have been observed. By midMarch, the ice in the W end of the lake starts to clear because of the temperatures and the prevailing W winds. The ice in this area is field ice and covers over an opened track.

(24) The central part of the lake remains open through January except for a few strips of thin ice. Growth is rapid in February, and high concentrations of thin ice develop by mid-month. By early March, medium-thickness lake ice predominates, with somewhat better conditions along the Canadian shore. Decay and clearing is rapid in mid-March, and the remaining pack is usually concentrated E of Long Point by the end of the month.

(25) In the E part of the lake, ice begins to form in early to midJanuary and may reach a thickness of 8 to 12 inches by the end of the month. The solid ice increases to 16 to 20 inches thick by the end of February. In Buffalo Harbor, an average thickness of 9

inches and an average maximum thickness of 18 inches can occur. In the lake, the prevailing W winds usually jam and pack the ice to form considerable windrows. Extremely hard pressure ridges 3 to 4 feet thick are not uncommon in February and March. As the ice on the rest of the lake begins to break up, the winds force it into the E end of the lake, and it completely blocks the approach to Buffalo Harbor. The soft deteriorating ice forms mush ice about 3 to 6 feet deep, interspersed with pressure ridges 4 to 6 feet deep. The mush ice has been reported as much as 20 feet deep in places. Rafted ice fields 15 to 20 feet above the water level have occurred during severe winters; under these conditions, ice can persist thought late May. (See Winter Navigation, chapter 3.)

(26) Submerged wellheads and pipelines.-Mariners are cautioned that oil and gas drilling towers are temporarily established in various parts of Canadian waters of Lake Erie. These towers have a quick flashing white light and an automatic fog signal that sounds one blast of 2 seconds duration followed by 18 seconds of silence.

(27) There are many submerged gas pipelines and wellheads in Canadian waters Lake Erie. Most of them are shown on the charts. Damage to these structures can be extremely hazardous because the natural gas if flammable, is under pressure, and contains toxic chemicals. Mariners are cautioned not to anchor in the vicinity of the submerged structures.

(28) Fish netting areas.-In parts of Lake Erie that are intensively fished, gill nets, impounding nets, and trap nets may create a hazard to navigation. The areas most intensively fished and the principal type of nets employed are shown in an inset on NOS chart 14820. However, fishing gear may be encountered at any location in the lake.

(29) Routes.-The Lake Carriers' Association and the Canadian Shipowners Association have recommended, for vessels enrolled in the associations, the following separation of routes for upbound and downbound traffic in Lake Erie.

(31)

Downbound vessels for Port Colborne or Buffalo, from point of departure, Southeast Shoal, shall lay a course of 071° for 135 miles to pass not more than 9 miles off Long Point; then steer 054° for 45 miles to Port Colborne or steer 063° for 60 miles to Buffalo..

(32) Upbound vessels from Port Colborne or Buffalo, to a point on the S shore, E of Marblehead, lay a course to pass not over 5 miles off Presque Isle Light. The course from Port Colborne is 228° for 62 miles, and the course from Buffalo is 236° for 77 miles.

(33)

Upbound vessels for Southeast Shoal from Port Colborne or Buffalo lay a course to pass not over 3 miles off Long Point. The course from Port Colborne is 241° for 44 miles, and the course from Buffalo is 248° for 60 miles; then steer 249° for 134 miles to a position 1 mile S of Southeast Shoal. (34)

Upbound vessels for Detroit River Light departing from a position 1 mile S of Southeast Shoal Light shall steer 302° for 8.5 miles to a position 323° 1.75 miles from Pelee Passage Light, then steer 275° for East Outer Channel Light IE.

(35) For Toledo and Monroe, when 0.75 mile off Pelee Passage Light steer 272° to pass 1.5 miles N of Middle Sister Island Light, thence to destination.
