Plant native streambank vegetation along Yegua Creek, site 1, Yegua Creek riparian corridor near Lake Somerville State Park and Trailway, Washington County, TX (2026-07-27)

A bare or eroding streambank reach along Yegua Creek near this public state park is losing sandy soil into the channel every high-flow event, ground that native switchgrass and eastern gamagrass would otherwise hold. Standard: Watershed health shoreline and streambank litter and condition assessment practice (Texas Stream Team style visual survey and hand removal), applied here to Yegua Creek's public access points near Lake Somerville State Park and Trailway. SDG 6.6 and 15.1. Proof: before/after photos + species/count record + GPS Method (Watershed health shoreline and streambank litter and condition assessment practice (Texas Stream Team style visual survey and hand removal), applied here to Yegua Creek's public access points near Lake Somerville State Park and Trailway. SDG 6.6 and 15.1.): 1. 1. Confirm the treatment reach with state park staff and photograph the bare or eroding streambank from an accessible bank edge before planting. 2. 2. Work only from the stable bank edge at low flow, never entering standing water or a flowing channel. 3. 3. Plant native switchgrass, eastern gamagrass, or black willow stakes at the design spacing along the accessible bank. 4. 4. Photograph the finished planting from the matching before vantage and record species and count. Done when: before/after photos + species/count record + GPS

$170 proposed

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 + species/count record + 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 30–60 minutes. Method of record: EPA dry-weather / AMD field screening

Bring

• GPS phone
• pH meter or strips
• conductivity meter
• ammonia + iron test kit as specified
• surfactant screen if specified
• gloves
• camera

Steps

1. 1. Navigate to the outfall/reach; record GPS; photograph it, capturing any visible flow or staining.
2. 2. Note whether flow is present in dry weather (yes/no).
3. 3. Measure and record pH, conductivity, and each specified analyte per kit instructions.
4. 4. Log any color, odor, floc, or aquatic-life observation.
5. 5. Enter all readings with units, GPS, time, and photos into the proof record; sign.

If it does not match the plan

• Dry-weather flow present with elevated conductivity/ammonia/surfactants -> flag suspected illicit discharge for the responsible agency.
• pH < 6 with visible iron floc -> tag suspected acid mine drainage; recommend metals lab panel.

What counts as done

• pH + conductivity recorded with units
• Each specified analyte recorded with a value
• Dry-weather flow present? recorded yes/no
• GPS waypoint + timestamped photo

Proof is measured against these, not judged by taste.
