A study was conducted to provide detailed mapping of glacial aquifers associated with the Fairport-Lyons channel system in Wayne, Ontario, and Seneca Counties, New York. The study was part of the cooperative Detailed Aquifer Mapping Program between the U.S. Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The objective of the study was to characterize the hydrogeology of the Fairport-Lyons channel and inter-drumlin aquifer system and to present the results as an electronic 1:24,000 scale map, hydrogeologic sections, and a summary report. The spatial extent and hydrogeologic framework of this valley-fill aquifer was delineated using existing data, including soils maps, well records, geologic logs, topographic data, and published reports. This data release contains digital datasets for the areas of surficial sand and gravel with water-resource potential, eskerform features, areas of sand and gravel or sand pits, delineated areas of p ...

Groundwater monitoring map

The map shows the location of the six hydrogeological regions in Canada and the location of observation wells. The terrain composition is also shown on the map, which includes crystalline rocks, mixed crystalline rocks, folded sedimentary rocks and flat lying sedimentary rocks. The southern limit of continuous permafrost zone and the limit of the discontinuous permafrost zone appear on the map. Canada has been divided into six hydrogeological regions on the basis of similarities of geology, climate, and topography. These six hydrogeological regions are (1) the Appalachians, covering the area of New Brunswick, Prince Edward Island, Nova Scotia, Newfoundland, and the Gaspé and Eastern Townships of Quebec; (2) the St. Lawrence Lowlands, covering Anticosti Island, the extreme southern area of Quebec, and the southern part of Ontario; (3) the Canadian Shield, lying north of the St. Lawrence Lowlands and extending northward to a line joining the north end of Lake Winnipeg to Anticosti Island; (4) the Interior Plains, lying approximately south of the southern limit of discontinuous permafrost and consisting largely of the southern prairie regions of the provinces of Manitoba, Saskatchewan, and Alberta; (5) the Cordilleran Region, the mountainous part of western Canada within British Columbia; and (6) the Northern Region, approximately covering the area north of the southern limit of discontinuous permafrost. To monitor the groundwater flow systems and fluctuations in these hydrogeological regions a series of groundwater observation wells and piezometers have been established in various parts of Canada, as is shown on the map. The groundwater observation well map indicates the extent of provincial observation well and piezometer networks in Canada. Because of scale limitations, the symbols on the map may indicate more than one well. These wells and piezometers have been established in the southern part of Canada to monitor groundwater fluctuations and may also be used to monitor groundwater quality. Since this region of Canada has the largest population density, groundwater is of more immediate interest here. In the areas of discontinuous and continuous permafrost little has been done at present to monitor groundwater conditions, although this is changing as mineral exploration looks north for new reserves.

The Forest Resources Inventory (FRI) provides information about tree species, including:

• composition
• height
• age
• density

Ontario’s forest resource inventories allow us to support resource management and land use decisions, and help sustain healthy, natural environments.

Forest resource inventories for each forest management unit are legally required under the Crown Forest Sustainability Act (1994). Every 10 years, the ministry creates a new forest management plan where inventory data is updated and must be compliant with the requirements detailed in the Act.

Ontario’s FRI is also used to meet provincial, federal, and international reporting requirements.

These draft FRI Packaged Product data sets are being provided for the purpose of consultation and product development. The number of attributes and the algorithms used to generate the attribute as well as the data formats will change over time and should not be considered the final version. A final version of the structure and content of the FRI will be made available after the required consultations are complete.

Data sets will be made available for each Forest Management Unit as they are produced.

For more information on the FRI please see: https://www.ontario.ca/page/forest-resources-inventory

To support improved groundwater geoscience knowledge for southern Ontario, a regional 3-D model of the surficial geology of southern Ontario has been developed as a part of a collaboration between the Ontario Geological Survey and the Geological Survey of Canada. Covering approximately 66,870 km2 in area, the model is a synthesis of existing geological models, surficial geology mapping, and subsurface data. The model is a simplified 9-layer reclassification of numerous mapped local surficial sediment formations in places over 200 m thick with a total volume of approximately 2,455 km3. The model integrates 1:50,000 scale surficial geology mapping with 90 m bathymetrically corrected topographic digital elevation model (DEM) and 8 existing local 3-D models. Archival subsurface data include 10,237 geotechnical and stratigraphic boreholes, 3,312 picks from geophysical surveys, 15,902 field mapping sites and sections, 537 monitoring and water supply wells and 282,995 water well records. Roughly corresponding to regional aquifer and aquitard layers, primary model layers are (from oldest to youngest): Bedrock, Basal Aquifer, Lower Sediment, Regional Till, Post Regional Till Channel Fill, Glaciofluvial Sediment, Post Regional Till Mud, Glaciolacustrine Sand and Recent Sediment / Organics. Modelling was completed using an implicit modelling application (LeapFrog®) complemented by an expert knowledge approach to data classification and rules-based Expert System procedure for data interpretation and validation. An iterative cycle of automated data coding, intermediate model construction and manual data corrections, expert evaluations, and revisions lead to the final 3-D model. A semi-quantitative confidence assessment has been made for each model layer surface based on data quality, distribution and density. This surficial geology model completes the development of a series of regional 3-D geological and hydrogeological models for southern Ontario.

Wetlands are lands that are seasonally or permanently flooded by shallow water, as well as lands where the water table is close to or at the surface. In either case, the presence of abundant water has caused the formation of hydric (moist) soils and has favoured the dominance of either hydrophytic (water-loving) or water tolerant plants.The term wetland is a general one and includes specific land types commonly called marshes, bogs, swamps and fens. Other terms sometimes used to describe wetlands include mires, sloughs and peatlands.Periodically soaked or wetlands being used for agricultural purposes that no longer exhibit wetland characteristics are not considered to be wetlands for the purposes of this definition.Wetland polygons are mapped independently from other hydrographic data classes and may overlap water bodies or other hydrographic data.Not all wetlands have been identified and mapped. Active maintenance is ongoing province-wide.Evaluators using the Ontario Wetland Evaluation System (OWES) will find additional guidance on the Ontario Wetlands evaluation page.For user friendly viewing of the wetland data, navigate to Ontario’s Make a Natural Heritage Map web application. This map application displays wetlands that have been evaluated using the Ontario Wetland Evaluation System as provincially significant or non-provincially significant. The application also displays wetlands that have not been evaluated but have been mapped using other procedures.*Due to limitations of the shapefile format, Wetland data can only be downloaded in the file geodatabase format (.gbd).

The Surficial Geology of Southern Ontario - Moraines feature displays areas of hummocky topography as well as areas mapped as moraines.

Revision note: The map has recently been revised and updated and replaces the map previously released on MRD 128.

The Surficial Geology of Southern Ontario data set is a GIS based geological map that shows the distribution and characteristics of surficial units across Southern Ontario. It illustrates surficial deposit types, material types, geological features (e.g. drumlins, eskers) and general bedrock types and outcrops. The surficial geology of southern Ontario consists largely of varying types and thicknesses of deposits emplaced primarily during the Quaternary period. These surficial deposits overly a bedrock terrain consisting mainly of Phanerozoic sedimentary rocks that overlie older Precambrian rocks of the Canadian Shield.

The data used in generating the map was derived from Quaternary maps, primarily at a scale of 1:50 000, completed by the OGS and Geological Survey of Canada (GSC) for most of southern Ontario over the past 40 years.

The Surficial Geology of Southern Ontario - Moraines feature is part of the Surficial Geology of Southern Ontario series. The other features are available on the GeoPortal and can be located by searching the following titles:
