Document a leaking irrigation canal segment near Tivoli, site 1, a public irrigation district canal right of way near Tivoli, TX 77990, Refugio County, upstream of the San Antonio Bay and Guadalupe estuary watershed (2026-07-30)

This public irrigation district canal segment near Tivoli shows active seepage or standing wasted water with no photo record to prioritize it for a hand seal, water that would otherwise never reach the San Antonio Bay watershed the whooping crane's blue crab food source depends on. Standard: USDA NRCS irrigation water management conservation practice plus Texas environmental flow standards for the Guadalupe Estuary and San Antonio Bay, applied here to a public irrigation district canal right of way near Tivoli, TX, Refugio County, upstream of the freshwater inflow that sustains San Antonio Bay's blue crab population, a core whooping crane food source. SDG 6.4 and 15.1. Proof: document only stand off photo log plus seepage condition note plus GPS plus ranked follow on note Method (USDA NRCS irrigation water management conservation practice plus Texas environmental flow standards for the Guadalupe Estuary and San Antonio Bay, applied here to a public irrigation district canal right of way near Tivoli, TX, Refugio County, upstream of the freshwater inflow that sustains San Antonio Bay's blue crab population, a core whooping crane food source. SDG 6.4 and 15.1.): 1. 1. From the public irrigation district canal right of way, photograph a leaking or overflowing canal segment without leaving the right of way. 2. 2. Note whether the segment shows active seepage, standing wasted water, or an intact sealed bank. 3. 3. Photograph the nearest canal marker or crossing structure for reference. 4. 4. Record a ranked follow on note naming the segment for the water conservation crew. Done when: document only stand off photo log plus seepage condition note plus GPS plus ranked follow on note

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. 1. Confirm the site/zone; record GPS; identify the system type (sprinkler / drip / micro).
2. 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. 3. Compute distribution uniformity (low-quarter DU) from the catch-can depths.
4. 4. Drip/micro zones: measure emitter flow at several points (fill a container over a fixed time) and inspect for clogs and leaks.
5. 5. Read operating pressure at the zone; note leaks, broken/misaligned heads, and overspray onto pavement.
6. 6. Review the run schedule against plant/soil need (over/under-watering, runoff).
7. 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

Proof is measured against these, not judged by taste.
