Description

This document clarifies authorization and application requirements under the Water Act and the Water (Ministerial) Regulation where excavations into the ground are proposed. Typically, excavations into the ground that may trigger Water Act authorizations are dugouts, borrow pits, pits, or other pits/excavations. This guide does not address excavations that may be created for the purpose of drainage, flood control, erosion control, or channel realignment. Also not addressed by this guide is the issue of whether evaporative loss is considered a "diversion of water" under the Water Act.

Description

Reports on the development of an integrated modelling framework established and implemented from April 2012 to March 2015, to provide a comprehensive understanding of hydrology, hydraulics, sediments, and contaminants within the Athabasca River and to inform current and future monitoring efforts. The broad objective of this part of the Joint Oil Sands Monitoring plan was to provide critical knowledge on and improved predictive modelling capability for water availability and sediment/contaminant transport in the lower Athabasca River.

Description

Reports on two studies developed to address science needs and gaps related to groundwater-surface water interactions on tributaries of the Lower Athabasca River and proximate to tailings ponds. The studies address to sub-themes of the groundwater theme identified in the Joint Canada-Alberta Oil Sands Monitoring program regarding water quality of the Lower Athabasca River, namely: What is the relative importance and contribution of groundwater quality and quantity to surface waters? and: Is there groundwater seepage from tailings ponds and/or other oil sands industrial operations entering the surface water system?
