advanced work · a working ranch parcel along the upper Green River, Big Piney, WY 83113
Rebuild the leaking wooden headgate on the hay-meadow irrigation ditch, a working ranch parcel along the upper Green River, Big Piney, WY 83113
This ranch's gravity-flow irrigation ditch waters the hay meadow through a decades-old wooden headgate that no longer seats tight, wasting a real share of the ranch's Green River water right to leakage before it ever reaches the field; rebuilding the gate to hold its set puts that water back where it belongs. Standard: USDA-NRCS Irrigation Water Control Structure (CPS 587) + Irrigation System, Surface and Subsurface (CPS 443); SDG 6.4 Proof: before/after photos + gate-seat/seal check + flow-set measurement + GPS Method (Mobile Irrigation Lab catch-can distribution-uniformity audit, ~60-120 min): 1. Confirm the site/zone; record GPS; identify the system type (sprinkler / drip / micro). 2. Sprinkler zones: lay catch cans on a grid across the zone, run the zone a fixed time, and measure the water depth in each can. 3. Compute distribution uniformity (low-quarter DU) from the catch-can depths. 4. Drip/micro zones: measure emitter flow at several points (fill a container over a fixed time) and inspect for clogs and leaks. 5. Read operating pressure at the zone; note leaks, broken/misaligned heads, and overspray onto pavement. 6. Review the run schedule against plant/soil need (over/under-watering, runoff). 7. Rank fixes (head repair, pressure regulation, schedule change) by water savings; record DU/emitter flow, pressure, leaks, schedule note, photos; sign. Equipment: matched catch cans (or cups), measuring cylinder / ruler, pressure gauge, stopwatch, GPS phone, camera, data sheet Done when: Distribution uniformity (or drip emitter-flow) recorded; Operating pressure recorded; Broken/leaking components + overspray noted; Schedule-vs-need note + ranked fixes + GPS + photos
How this work is done
A documented method, so this packet comes out the same whoever does it. Typically 60–120 minutes. Method of record: Mobile Irrigation Lab catch-can distribution-uniformity audit
Bring
- matched catch cans (or cups)
- measuring cylinder / ruler
- pressure gauge
- stopwatch
- GPS phone
- camera
- data sheet
Steps
- 1. Confirm the site/zone; record GPS; identify the system type (sprinkler / drip / micro).
- 2. Sprinkler zones: lay catch cans on a grid across the zone, run the zone a fixed time, and measure the water depth in each can.
- 3. Compute distribution uniformity (low-quarter DU) from the catch-can depths.
- 4. Drip/micro zones: measure emitter flow at several points (fill a container over a fixed time) and inspect for clogs and leaks.
- 5. Read operating pressure at the zone; note leaks, broken/misaligned heads, and overspray onto pavement.
- 6. Review the run schedule against plant/soil need (over/under-watering, runoff).
- 7. Rank fixes (head repair, pressure regulation, schedule change) by water savings; record DU/emitter flow, pressure, leaks, schedule note, photos; sign.
If it does not match the plan
- Low-quarter DU < 0.65 (sprinkler) -> flag poor uniformity for repair/redesign.
- Visible runoff or overspray onto pavement -> flag schedule/head correction.
- Emitter clogging or line leaks (drip) -> flag maintenance.
- Broken/misaligned head -> flag for repair. Documentation only; no repairs by surveyor.
What counts as done
- Distribution uniformity (or drip emitter-flow) recorded
- Operating pressure recorded
- Broken/leaking components + overspray noted
- Schedule-vs-need note + ranked fixes + GPS + photos
