A dredge superintendent's comment on my slurry mix changed my whole summer

Ran a job on the Meramec River last July and kept getting flak for slow progress. A superintendent said my slurry was too thin, dumping extra water just to keep it moving. I fought it for two weeks, thinking thicker would clog the line. Finally tried his way, cut water at the pump and ran 12% more yardage per day. Anyone else had a boss whose offhand advice on viscosity actually saved their season?

Old-timer in Galveston had a point about slow swings

Last month a retired operator watched me work the cutter for 10 minutes and said my swing speed was leaving too much spoil. I argued it was about volume, but he timed my cycles and showed me 3 extra passes per cut because I was tearing material. Tried his slower pace for a week and my fuel use dropped 11 percent per shift, so maybe the old ways still hold up. Anyone else get a better result from easing off the throttle?

Dredged the same 2 miles of creek for 8 years, the bottom changed completely after one big rain

Back in March we had that 6 inch downpour up near the Johnson Creek headwaters, and I figured the usual silt would pile up like always. But when I got the cutterhead running the next week, the material felt different, more gravel than mud, and the draft dropped by nearly a foot in spots I'd been fighting for years. The flood must have scoured out all that packed clay that was building up since 2016, and now the channel holds its depth twice as long between passes. Has anyone else seen a single storm event reset a stretch of riverbed that fast, or was this just a lucky one-off?

Hit 40,000 cubic yards on my cutterhead last Tuesday in Toledo, never expected that number so early in the season

Saw this on the Mississippi near Baton Rouge, the silt settled weird after the last storm

The old pump house on the Missouri had a setup I'd never seen

The moment I realized my cutter suction was set up backwards

Spent 3 days chasing a sand plug that turned out to be a busted wear plate

Fouled intake for 3 days over a blocked sump screen

Sand bar shifted 40 feet overnight at the mouth of the Warrior River

Near miss on the Mississippi last Tuesday, check your swing cables

Took me 2 months to stop fighting the current on the Mississippi bend

Wasted $450 on a hydraulic cutter I barely use

Hit 1,000 hours on my cutterhead today, felt weirdly proud

Can we talk about how everyone swears by the short suction pipe?

That old-timer in Astoria changed how I read the river

Debate: Is a $900 spare pump stack worth it or just dead weight on the barge?

Never thought about silt density until I ran the numbers on our impoundment

Cable arm vs hydraulic arm for snag clearing, the difference is night and day

Just realized my cutterhead speed was way off after a rocky month on the Missouri River

Three years swinging a dredge before I figured out the swing speed trick

That dredge site near the old mill pond was way cleaner than I expected

The day I realized my dredge bucket was clogged for 3 months straight

Noticed a huge difference after I started greasing the swing bearings every 40 hours instead of 60

Rant: That job on the Mississippi River changed how I run my cutterhead
