Abstract
The Peace-Athabasca Delta (PAD) is a complex, dynamic, and misunderstood ecosystem. This study uses landscape, ecological, climatic, hydrologic, historical, stratigraphic, and wildlife data that document how and why the PAD has changed and varied from ~1900 to 2023. The ecological, climatic, and hydrologic components of the ecosystem vary in concert. Flood-drawdown cycles influenced by physical and biological factors have driven a host of landscape changes over the past 120 years. Prior to regulation, net drying of the PAD took place over the period ~1900 to the mid-1940s. Since mid-20th century, there has been no multidecadal drying trend but rather decadal-scale wet and dry episodes. Levels of the confluent Lakes Athabasca, Claire, and Mamawi, and their adjacent restricted basins, are strongly correlated with the combined flows of the Peace, Athabasca, Fond du Lac, and Birch Rivers. River regulation has changed the seasonal distribution of flows and suppressed summer flows. There is, however, no evidence that ‘dramatic landscape change is underway, devastating local fauna’ or that river regulation has caused delta desiccation, declines in spring flooding, declines in lake levels, or declines in wildlife, waterfowl, or their habitat. The great areal extent of the PAD watershed imparts hydrologic and ecological resilience.

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; both teacher heads agree on what is shown here.
