Upper Lakes Shipping Ltd. Vessels Scrapbook, 1964-1967, no date

The origins of Upper Lakes Shipping can be traced back to 1931, when Gordon Leitch, the general manager of Toronto elevators, sent Captain Bruce Angus to scout for potential ships that could be used to transport grain. The ship Sarnian was purchased as a result. It soon became apparent that more ships would be needed by the business, and Leitch subsequently partnered with James Norris of the Norris Grain Company, in order to transport their products more economically. The Upper Lakes and St. Lawrence Transportation Company (which later become known as Upper Lakes Shipping), was incorporated in 1932. In 1956, the company bought Port Weller Dry docks. At this point, the company began constructing new vessels designed to meet specific freight and classification needs.

Niagara River (Ontario) Remedial Action Plan fonds, 1984-1997, n.d.

The Niagara River Remedial Action Plan was part of an initiative to restore the integrity of the Great Lakes Basin ecosystem. In 1972, the Great Lakes Water Quality Agreement was signed by both Canada and the United States to demonstrate their commitment to protecting this valuable resource. An amendment in 1987 stipulated that Remedial Action Plans (RAPs) be implemented in 43 ecologically compromised areas known as Areas of Concern. The Niagara River was designated as one of these areas by federal and provincial governments and the International Joint Commission, an independent and binational organization that deals with issues concerning the use and quality of boundary waters between Canada and the United States. Although the affected area included parts of both the Canadian and American side of the river, Remedial Action Plans were developed separately in both Canada and the United States. The Niagara River (Ontario) RAP is a three-stage process requiring collaboration between numerous government agencies and the public. Environment Canada, the Ontario Ministry of the Environment, and the Niagara Peninsula Conservation Authority are the agencies guiding the development and implementation of the Niagara River (Ontario) RAP. The first stage is to determine the severity and causes of the environmental degradation that resulted in the location being designated an Area of Concern; the second stage is to identify and implement actions that will restore and protect the health of the ecosystem; and the third stage is to monitor the area to ensure that the ecosystem’s health has been restored. Stage one of the RAP commenced in January 1989 when a Public Advisory Committee (PAC) was established. This committee was comprised of concerned citizens and representatives from various community groups, associations, industries and municipalities. After several years of consultation, the Niagara River (Ontario) Remedial Action Plan Stage 2 Report was released in 1995. It contained 16 goals and 37 recommendations. Among them was the need for Canadians and Americans to work more collaboratively in order to successfully restore the water quality in the Niagara River. Stage three of the Niagara River (Ontario) RAP is currently ongoing, but it is estimated that it will be completed by 2015. At that point, the Niagara River Area of Concern will be delisted, although monitoring of the area will continue to ensure it remains healthy.

Critical evaluation of diameter increment modelling in the Great Lakes region

Simulations of forest stand dynamics in a modelling framework including Forest Vegetation Simulator (FVS) are diameter driven, thus the diameter or basal area increment model needs a special attention. This dissertation critically evaluates diameter or basal area increment models and modelling approaches in the context of the Great Lakes region of the United States and Canada. A set of related studies are presented that critically evaluate the sub-model for change in individual tree basal diameter used in the Forest Vegetation Simulator (FVS), a dominant forestry model in the Great Lakes region. Various historical implementations of the STEMS (Stand and Tree Evaluation and Modeling System) family of diameter increment models, including the current public release of the Lake States variant of FVS (LS-FVS), were tested for the 30 most common tree species using data from the Michigan Forest Inventory and Analysis (FIA) program. The results showed that current public release of the LS-FVS diameter increment model over-predicts 10-year diameter increment by 17% on average. Also the study affirms that a simple adjustment factor as a function of a single predictor, dbh (diameter at breast height) used in the past versions, provides an inadequate correction of model prediction bias. In order to re-engineer the basal diameter increment model, the historical, conceptual and philosophical differences among the individual tree increment model families and their modelling approaches were analyzed and discussed. Two underlying conceptual approaches toward diameter or basal area increment modelling have been often used: the potential-modifier (POTMOD) and composite (COMP) approaches, which are exemplified by the STEMS/TWIGS and Prognosis models, respectively. It is argued that both approaches essentially use a similar base function and neither is conceptually different from a biological perspective, even though they look different in their model forms. No matter what modelling approach is used, the base function is the foundation of an increment model. Two base functions – gamma and Box-Lucas – were identified as candidate base functions for forestry applications. The results of a comparative analysis of empirical fits showed that quality of fit is essentially similar, and both are sufficiently detailed and flexible for forestry applications. The choice of either base function in order to model diameter or basal area increment is dependent upon personal preference; however, the gamma base function may be preferred over the Box-Lucas, as it fits the periodic increment data in both a linear and nonlinear composite model form. Finally, the utility of site index as a predictor variable has been criticized, as it has been widely used in models for complex, mixed species forest stands though not well suited for this purpose. An alternative to site index in an increment model was explored, using site index and a combination of climate variables and Forest Ecosystem Classification (FEC) ecosites and data from the Province of Ontario, Canada. The results showed that a combination of climate and FEC ecosites variables can replace site index in the diameter increment model.

Occurrence and geochemistry of lake-bottom manganiferous deposits in Canadian lakes

It is the purpose of this paper to record information concerning the distribution and occurrence of manganiferous concretions and other manganese oxide deposits that develop on certain lake bottoms. During the summer of 1935 several days were devoted to a study of this type of lake bottom deposit in various parts of Nova Scotia. Lake studies in Ontario have extended the known distribution from lakes on or near the Atlantic coast to lakes in southern Ontario. During the writer's first work on lacustrine manganiferous deposits the concretions of manganese oxide which were found were almost entirely limited to the relatively shallow parts of the lakes examined. Other lakes are now known where the manganese oxide appears to occur only in the maximum depths.

Troubled Waters Ahead: An Evaluation of Shoreline Land Use Policies for Water Quality Protection in Renfrew County, Ontario

Increases in the rate and extent of lakeshore development along inland lakes in Ontario are adversely impacting water quality. Despite growing awareness, there is a lack of knowledge about the land use policies and tools in place to protect inland lakes in rural Ontario. This research evaluated official plans for water quality protection policies for inland lakes in the County of Renfrew, Ontario to address this gap. The findings suggest that municipalities implicitly link water quality to land use planning policy and fail to incorporate innovative methods to protect water quality.

(Table 1, page 605) Chemistry of concretions from Grand Lake (GL) and Ship Harbour Lake (SH), Nova Scotia and Mosque Lake (ML), Ontario

Studies by optical microscopy, x-ray diffraction, and electron probe techniques of ferromanganese concretions from three Canadian lakes reveal chemical banding of amorphous hydrated iron and manganese oxides. The average ratio of iron to manganese in concretions from these lakes varies from 0.43 to 2.56. The concentrations of cobalt, nickel, copper, and lead are one to two orders of magnitude below those reported for oceanic ferromanganese concretions.
