Seal 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)

The survey above found a leaking or overflowing segment of this public irrigation district canal near Tivoli, and a hand sealed bank plus a small tailwater catch berm would otherwise keep sending freshwater to waste instead of downstream toward San Antonio Bay. 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: before after photos plus length sealed record plus GPS 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. Confirm the seepage segment with irrigation district staff and photograph the leaking or overflowing stretch before starting. 2. 2. Hand seal small canal bank seepage points with hand tools only, no power equipment, staying on the public right of way. 3. 3. Hand build a small tailwater catch berm below the segment to capture and return any residual runoff to the canal. 4. 4. Photograph the sealed segment and finished berm from the matching before vantage and record the length sealed. Done when: before after photos plus length sealed record plus GPS

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

before after photos plus length sealed record plus GPS

This is exactly what gets it approved. Nothing settles without it.

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.
