Constructing habitat for a sustainable native fisheries in the Sphinx Lake end pit lake system
Bibliographic record
Abstract
Fisheries habitat and watershed integrity are highly valued resources in the subalpine natural subregion of west-central Alberta. Teck’s Luscar open pit coal mine has been in operation in this area since 1969, and 51-C6 pit was mined from 1992 to 1999. Accomplishing a sound development and reclamation plan to meet biodiversity objectives for 51-C6 pit included operational considerations such as surface water diversions and post-mining fisheries habitat development. The pit had to be mined and reclaimed such that the end pit and inlet/outlet streams would sustain in perpetuity the full range of habitat and watershed features needed to support native Athabasca Rainbow Trout (Oncorhynchus mykiss) and Bull Trout (Salvelinus confluentus). The five year post-reclamation fisheries habitat and population assessment indicates a surging Rainbow Trout population, high growth rates and enhanced habitat conditions as compared with the pre-mine cold-water, lotic system. This paper covers the process from environmental assessment through construction and reclamation to closure assessment, highlighting the challenges, uncertainties, and successes of Teck’s award-winning Sphinx Lake system within the context of biological diversity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
