Description

Alberta Environment and Parks (AEP) is continuing with an environmental monitoring program in an area north of the former Canada Creosote Site and the Bow River in northwest Calgary, referred to as the North Bow Site. Advisian was awarded a five-year (2017-2021) contract to complete the North Bow Site environmental monitoring work. This executive summary provides an overview of the findings of works completed in the first year of this program from March 2017 to March 2018.

Post-2013 flood historic resource assessments of the Sheep, Highwood, and Bow rivers and their contribution to a regional understanding of the precontact landscape

Historic resources assessments of the impacts the 2013 flood on palaeontological and archaeological resources adjacent to the Bow, Sheep, and upper Highwood rivers in southern Alberta were... More ≫

Description

Historic resources assessments of the impacts the 2013 flood on palaeontological and archaeological resources adjacent to the Bow, Sheep, and upper Highwood rivers in southern Alberta were conducted between 2013 and 2015. These studies visually assessed erosional exposures on these rivers and documented historic resources. Analysis of the location and character of these finds has shed light on the types of landforms present and the nature of human occupations in the Bow River watershed, and highlights how significant the impact of flood-related erosion has been on historic resources. This paper discusses these finds in a regional context to integrate them into the larger geological and precontact landscape contexts of southern Alberta. Part of the 37th volume of the Archaeological Survey of Alberta Occasional Paper series, which contains 18 articles exploring multiple facets of the impact on archaeological resources of the 2013 flood in southern Alberta.

Description

Excavations in 2015 at EePj-103, Margaret’s Site, revealed a stratified Protohistoric and Historic Period site. A unique feature of this site is that it has two stratigraphically separate protohistoric occupations, neither of which are mixed with earlier Precontact Period materials nor later Historic Period materials. EePj-103 also has later Historic Period occupations, at least one of which is associated with the Domburg Ranch, established in 1889, and represented today by the remnants of sandstone building foundations. EePj-103 is uniquely positioned to help answer important research questions about the Protohistoric Period in southern Alberta, particularly those related to changing technology with the introduction of European trade goods. The historic ranch remains also represent a very early period in the settlement of Alberta after the building of the Canadian Pacific Railway. Part of the 37th volume of the Archaeological Survey of Alberta Occasional Paper series, which...

Description

Water quality surveys were conducted throughout the Bow River basin during low-flow conditions in the summers of 1994 and 1995. These surveys were designed to assess the impact on the mainstem Bow River of specific tributaries, irrigation return flows and effluents, and to address a recommendation of the Bow River Water Quality Task Force concerning the integration and optimization of sampling efforts by different stakeholder groups.

Description

Water quality in southern Alberta's Bow River, as measured by bacteriological indicators, has been affected by increasing population and development in the Bow Basin. This report documents levels of coliform bacteria in the Bow River for three time periods: 1951-52, 1967-75, and 1978-94, and includes data compiled from all agencies sampling in the Bow River basin for over 45 mainstem sites and for a number of tributaries.

Description

This report presents the results of 1986-88 Bow River water quality monitoring programs conducted by Alberta Environment. Plant nutrient, coliform bacteria count and aquatic plant biomass trends and differences between sites were analyzed. This program was mainly designed to detect changes in river water quality since the installation of phosphorus removal at Calgary sewage treatment plants in 1982-83.
