Dauphin Lake basin water level Vertical stack of threshold zones showing where the current Dauphin Lake level sits. Above the waterline, threshold bands retain warning colors. Below the waterline, submerged bands appear in grayscale and are tinted with light blue water. A translucent ice sheet sits at the current level during pre-breakup season.

Outlet Monitor  ·  Mossy River Dam

Water exits through the Mossy River dam at Terin's Landing. When the lake is high, the river channel itself — not the dam — limits outflow to ~500 cfs. In 2011, inflow peaked at 60,000 cfs. The lake rose.

Basin Snowpack — Contributing Context

The 2026 season opened with 160–185 mm SWE near Riding Mountain — the highest recorded snowpack in this dataset, exceeding even 2011 and 2014. High-elevation headwaters broke April 14 and ran hard through late April. That water has now passed through the watershed; residual at upper elevations is minor. Based on HFC field measurements (March 9–12) · Estimated · April 14, 2026

Loading forecast…
Watch for: Sustained rain accelerates lake rise on a charged basin. Strong winds can push effective waterline well above gauge readings on the downwind shore. Above-normal temperatures forecast through June 2026 (IRI / all models agree).
