Water Makes Grass Grow!
That is a theme I frequently use in my grazing management presentations around the country. I often say I have learned more about grazing management by working the last dozen years in the extremes of
Jim: I assume you have gotten your nozzle package fixed for the proper pressure and flow rate for each pivot. You didn’t mention this. Do you use pressure regulators? If so, closing the valve down may have reduced pressures below the minimum for regulators to even work, and nozzles (even if new) will not work as designed. If you are not using pressure regulators, that is one option you could look into so you don’t have to close the valve down. Glad to provide a little pro bono advice if you are interested.
You pictures do show an amazing difference in pasture growth.

The system had pressure regulators on the drops. Because our water is unfiltered direct from the creek, we get a lot of scouring through the regulators & nozzles. Ir was time they needed to be changed. It is in the budget for next year & will happen in the Spring.
OK. Good deal. Check your pressures, even if you put new regulators and nozzles on. You must maintain 5 psi above pressure regulator PSI. I had one this year that was 40 psi at 900 gpm. When the flow decreased to 700 gpm the pressure went below the minimum for regulators. They ceased to work, and pressure dropped clear down to 14 psi.
