The Nepal flood disaster continues to evolve. The drainage of the lower landslide-dammed lake last week undercut riverbanks, resulting in further small landslides. The huge volumes of sediment mobilized and redeposited during this event will remain unstable for many years to come. @planet.com 🧪⚒️

Based on their results, the USGS researchers estimate between one-third and half of the nutrients in streams came from “lagged, non-point sources.” This means it took longer than one season for nitrogen or phosphorus to move from soil or groundwater into a waterway.

⚒️ We were in New Hampshire last weekend and discovered this gem: Sabbaday Falls cuts down through a basaltic dike intruded into the surrounding granite. A highly effective visual demonstration of these rocks' relative hardness!

View up a narrow stream running down a straight slot canyon, about 1m wide. At the end of the canyon, a waterfall can be seen plunging into a deep blue pool which extends almost to where the picture is taken from, at which point it shallows and runs over a dark black rock, which is very distinct from the white-pink rock that surround the canyon. This black rock can be seen on the right inner wall of the canyon jn front of the waterfall, and also behind the waterfall (if you squint). The waterfall is clearly eroding through a basaltic dike that intrudes the surrounding basalt. Part of another dark basaltic dike can be seen intruding the granite in the right foreground.

View from above the waterfall seen in the first picture. Water is cascading down a granite face into a clear into the linear gash formed by erosion of the basalt dike, which can be seen clearly in its uneroded form, with a granite stringer, on the back wall on the right of the picture.

The USGS report I mentioned says that lake evaporation has increased - probably a lot to do with increased surface area- but not as much as precipitation and inflows. And extra evaporation doesn't necessarily produce rain locally.

Playing with Google Earth, you see Devils Lake level rising before the smaller lakes take off ... so I think it's a bit of both: river inputs exacerbated by lake overflows. But I am not an expert.

How long will Devils Lake remain in a wet cycle and at such a large extent? We don't know. The USGS says wet cycles average around 30 years, but it's been longer than that already. In 2008, a USGS report gave it a 37% chance of lasting through 2038. So far, their predictions are right on track.

The state of ND has constructed 2 outlets from Devils Lake to try to control levels, and the Corps completed work to stabilize the natural outlet. Levees, roads, and bridges have been raised. Costs to date? >$500 million pubs.usgs.gov/sir/2008/501... Photo from ND Dept of Water Resources

Paleoflood records indicate at least 2 natural spills of the lake in the last 4000 years. Such a spill now would mean catastrophic flooding for downstream communities.

Anne Jefferson @annejefferson.bsky.social · 10/03/2026

Why has Devils Lake risen so dramatically? Precipitation has gone up, likely due to natural climate cycles. Which cycles? This 2008 USGS report says it's complicated to disentangle. But the historical estimated precipitation and inflows really tell the story. pubs.usgs.gov/sir/2008/501...

1993 wasn't even the lowest of the low for Devils Lake. In 1940, it was 1400.9 ft and nearly dry. The multidecadal rise in Devils Lake water has had significant economic costs, destroying hundreds of homes and businesses and submerging 1000s of acres of farmland. www.swc.nd.gov/pdfs/dl_fact...

Anne Jefferson @annejefferson.bsky.social · 10/03/2026

Devils Lake (ND) flooding occurs because there are no natural outlets to the lake until it reaches an elevation of 1458 ft. Back in 1993, it was ~1422 ft. At that elevation it covers ~69 sq. miles. Today, the lake surface is at 1449 ft, and it covers 213 sq. miles. ND is flat.

Aerial imagery of Devils Lake, ND in December 1993 shows a small lake with several basis and lots of agriculture and prairie land

Aerial imagery shows Devils Lake ND in July 2025 with a much larger lake than 1993, and a large Lake Alice to the north that is nearly absent in 1993.

Tonight, I was looking at water.noaa.gov to see where the US is flooding. My 11-year old pointed to the ongoing major flooding in North Dakota, and I said "Oh, that's Devils Lake. It's always flooding there." They asked "Why?" and a rabbit hole yawned before me.
