Dad’s getting ready for some new stock in the lake this year - esp excited about his new flock of Grass Carp headed this way in March.
Given how sneaky those young teenage Carp are - he’s building a fish gate for the spillway.
Measure 3 times, weld it twice.

He’s making it stick together. No one can see the welds underwater!

Nice little design. Fits perfect in the spillway.
That’s a proud engineer with a nice little fish gate.
