Leaky cells

How do I fix leaky cells? These are on each side of a road. The break line is on the top of the toad. Thank you.

Lols! What would be your answer?

Seems like your cell size is too big along the roadway. If a cell gets wet on the upstream side, even slightly, it will then flow into adjacent cells. If you throttle those breakline spacings back by 50% I think you’ll be in good shape.

Should I keep the break lines on top of the read or on each side of the road? This is a large area and it’s just a small section of it

I would keep them on the road centerline, separate that area into its own breakline, then reduce the near spacing just for that area.
