Hand-stabilize an eroding earthen tank bank-top, a public bank-top vantage of the Fort Griffin State Historic Site earthen stock tank, site 1.

The survey above found active bank-top erosion at the Longhorn herd's earthen stock tank at Fort Griffin State Historic Site; hand-placed rock and brush along the eroding edge, worked entirely from stable bank-top ground, slows further loss of the earthen dam without ever entering the water.

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

bank top only confirm plus before after photos plus material record plus GPS of the public vantage only

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

• Before photo of the eroding bank-top section
• Confirmation the work stayed bank-top only, never entering the water
• Confirmation that this work never entered a pasture holding livestock, never approached, herded, handled, restrained, treated, or fed any animal, and never worked among cattle, observing and working only from a public trail, designated visitor area, or the outside of a fence line with the stand-off distance stated; that any exclosure plot work happened only in staff-approved, confirmed-ungrazed ground, never inside an active pasture; that any earthen-tank work happened bank-top only, outside the pasture fence, never entering the water, wading, or sampling; that no precise coordinate of the ear
• Rock or brush material used recorded
• After photo of the finished bank-top placement

Proof is measured against these, not judged by taste.

The standard this serves

Watershed Health. A watershed is everything the land pours into a stream, and the stream keeps the record. The EPA's bioassessment method reads that record through the small creatures living in the gravel: mayflies and caddisflies mean clean water, only worms and midges mean trouble. Mastery looks like a person who can wade one riffle with a net and tell you how the whole valley is doing. That skill is built sample by sample. This packet is one of them: one site, one careful count, one entry in the long record of a stream.
