Minimum flows for sustaining summer water quality in constructed fish habitat in the lower mainland of British Columbia
Bibliographic record
Abstract
Constructed fish habitat is created to offset destroyed and degraded fish habitat. Reviews from government and research organizations indicate that constructed fish habitats often do not function as intended. To address this shortcoming, a summer survey of 26 constructed off-channel fish habitats in the Lower Mainland of British Columbia was conducted in 2019 to quantitatively assess design features of constructed fish habitats. Linear regression was used to estimate minimum turnover flows needed to sustain appropriate water quality for salmonids during rearing summer conditions. Model results suggest that flows of approximately 1 L/s are required to maintain water quality in 70 m3 of habitat volume and indicate that proximity to development increases the flows needed to sustain water temperatures. These findings are intended for use by biological practitioners and regulators to estimate minimum flow requirements for constructed fish habitat at the planning stage in advance of construction.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
