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

In 2014, Stantec Consulting Ltd. carried out an in depth survey of the Highwood River valley for archaeological, historic, and palaeontological resources. In addition to revisiting known sites and recording new ones, the project provided risk assessments relative to flood related impacts and site management strategies. New sites were recorded all along the Highwood River and several known sites were found to be much richer than previously thought. Additionally, numerous new Quaternary microfaunal, macrofaunal, and palaeoenvironmental sites were recorded during the palaeontological survey. This paper presents a brief summary of the program, including a case study of a joint archaeological and palaeontological locality. 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

In 2016, preliminary excavations were conducted at EdPm-7 and EePl-261 along the Highwood River south of Calgary. The sites were heavily impacted by the 2013 floods and continue to be threatened by future flood events. Excavations, diagnostic artifacts, and radiocarbon dating confirmed that EePl-261 and EdPm-7 are Late Precontact Period sites. Eight interesting in situ features were identified and excavated, which contribute to a better understanding of camp life and settlement patterns along the Highwood River. 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

Assessment excavations were completed in the fall of 2016 at the Spitzee Post (EdPl-13) and the Metke Site (EdPl-10). Recognizing the value of historic resources along these drainages, these archaeological studies were conducted to assess erosional impacts of the 2013 flood on these two sites. Conclusions highlight the importance of this ford on the Highwood River over the last 5,000 years or more. 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.

Reconstructing the Highwood River’s Holocene palaeoecology : assessment of organic-rich alluvial samples collected following the 2013 flood event

Description

Periodic flood events are normal for rivers. These events sometimes deposit sediments that trap biological remains that can be used to reconstruct the local environment. Following the 2013 flooding of the Highwood River, southwestern Alberta, 24 organic-rich palaeoenvironmental samples were collected from the river’s banks at 14 localities. Data synthesis generated a detectable signal of climatic change throughout the Holocene. The general trend shows a progression from drier conditions in the early Holocene towards relatively moist conditions today. This study is the first detailed examination of near-river palaeoenvironmental conditions in southern Alberta.

Description

Twin Valley Reservoir was first filled in 2003 following construction of a new dam on the Little Bow River near its confluence with Mosquito Creek. To fill and operate the new reservoir, increased diversion from the Highwood River to Women’s Coulee and to the Little Bow River occurs in spring according to an approved water management plan. An existing lake, Clear Lake, was also stabilized by diversion from Mosquito Creek near the mouth first operated in 2002, and additional enhancements. This report presents an evaluation and statistical analysis of water quality in Twin Valley Reservoir, Clear Lake, and their tributaries that was prepared using intensive monitoring data collected by Alberta Environment from 1999 to 2010, with reference to previous baseline sampling where needed for statistical testing.

Twin Valley Dam environmental monitoring program : Little Bow River and Mosquito Creek fish inventory project, 2014

Description

The report describes the fish communities of the Little Bow River and Mosquito Creek, based on the results of field sampling conducted in 2014. Assessment of the fish community was completed as part of the Twin Valley Dam environmental monitoring program. Monitoring was intended to determine the environmental impacts of the construction and operation of Twin Valley Dam and the effectiveness of environmental mitigation measures. In 2014, the fish assemblages in the Little Bow River and Mosquito Creek were generally unchanged compared to previous post-dam monitoring results. The Little Bow River fish assemblage is influenced by entrainment of fish from the Highwood River upstream from the Twin Valley Dam Reservoir and by movement and migration of fish from Travers Reservoir, downstream from Twin Valley Dam.
