Description

This map displays the risk of soil degradation by water in the agricultural region of Alberta. Water erosion is a concern because it reduces soil quality by removing soil particles and nutrients, and reduces water quality if these particles are carried into nearby water bodies. The map uses five classes to describe the water erosion risk on bare, unprotected mineral soil: negligible, low, moderate, high and severe.This resource was created using ArcGIS, originally published as a print map in 1993 .

Description

Describes the field protocols and methods for the measurement of precipitation using the OTT Pluvio precipitation gauge. These protocols are important to ensure that data are collected consistently and the data obtained are accurate and scientifically sound. The information that is gathered is critical for flood forecasting and water supply, the accurate prediction of runoff, long-term hydrological analysis, agricultural insurance assessment, and to assist in the operation of reservoirs and hydroelectric facilities in Alberta.

Lotic Riparian - Strahler Order Derived

Description

This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. Riparian areas consist of the lands adjacent to streams, rivers, wetlands and lakes that are strongly influenced by the presence of water. They are often distinct from the surrounding landscape as the vegetation growth is very lush. These areas form a transition between dry land and open water and are characterized by the presence of hydrophilic vegetation and specific soil types. Riparian areas are usually very productive in terms of biomass and form critical wildlife habitat. Additionally, these areas often have standing water and are subjected to periodic flooding when high water levels fill the stream channel to the top of the bank. The term 'riparian' is derived from the Latin word for river bank. Riparian areas provide valuable food, shelter and travel corridors as well...

Description

Pine Lake is a small eutrophic lake southeast of Red Deer, Alberta. Public concern over deteriorating water quality prompted the Alberta government to initiate a lake restoration program in 1991. The Pine Lake Restoration Program was intended as a pilot project for future lake and watershed projects in Alberta. An advisory committee that represented all stakeholders in the community directed early planning and problem diagnosis by technical advisors from the Alberta government. A diagnostic study in 1992 determined that approximately 61% of the total phosphorus (TP) loading was from sediment release and other internal sources, compared to about 36% from surface runoff, and determined that nuisance algal blooms in Pine Lake were mainly controlled by the supply of phosphorus.

Impacts of agriculture on surface water quality in Alberta

Description

Part 1 -The Haynes Creek Study was one of three studies funded under the Canada-Alberta Environmentally Sustainable Agriculture agreement (CAESA) to describe the effects of agriculture on surface waters in Alberta. This study was conducted in the Haynes Creek watershed to determine if runoff from cattle wintering grounds and from cultivated fields had a direct, measurable influence on stream water quality. The Haynes Creek watershed (east of the city of Red Deer) was selected because it was considered representative of very intensive agricultural activity on a landscape sensitive to water erosion. Part 2 - The Provincial Stream Survey was one of three studies funded under the Canada-Alberta Environmentally Sustainable Agriculture agreement (CAESA) to describe the effects of agriculture on surface waters in Alberta. This study was conducted to determine if there are relationships between the agricultural intensity in the drainage basins and water quality of streams. Part 3 - Federal...

Description

This study provides a first step in assessing effects of storm and combined sewer discharges on water quality in the North Saskatchewan River. Results generally confirmed conclusions from other studies conducted by Alberta Environmental Protection and the City Of Edmonton that these discharges are a significant source of pollutants to the river during wet weather.
