What is this article about?
The Conemaugh lake reservoir, largest in the U.S., belonged to the South Fork Fishing and Hunting club of Pittsburg men; its dam, 110 feet high, was believed breached when a cloudburst added water faster than it could hold.
Quality green show the numbers
Measured from the scan
— how cleanly the OCR engine read the characters
- Mean ink quality
- 99.0% The length-weighted average confidence across the OCR lines — the mean of exactly the per-line scores whose tails the two figures below report. Typical is 99%.
- Illegible ink
- 0.0% Text sitting in OCR-detected lines that scored below 80% confidence — very shaky reads. Weighted by line length, so one long bad line counts for more than a short one.
- Uncertain ink
- 0.0% Text in lines that scored 80–90% — somewhat shaky reads.
- Matches source
- 98.78% How closely the served text matches the raw OCR of the same boxes, letter by letter, after collapsing spacing and case. This measures agreement, not correctness: the OCR is often wrong and the extractor corrects it, so 100% does not mean perfect, and a low figure usually means poor scan text was rewritten rather than that text was lost (length vs source shows loss).
- Length vs source
- 98.84% Below 100% means text was dropped from the OCR; above means text was added to make it read.
Assembled by the extraction model
— whether the stitched-together text holds up; catches layout and segmentation errors, which the scores above cannot see
- Transcription confidence
- 96.0% (typical 96%) How cleanly the extractor could assemble what it was given. Low here with clean ink scores points at layout analysis — the characters were read correctly but grouped or ordered wrongly.
- Comprehension
- 95.0% Whether the piece reads coherently start to finish. Can stay high while transcription confidence drops, when only part of the component is affected.

Largest Reservoir in the Country.
GREENSBURG, Pa., June 1.—The reservoir was situated eighteen miles northeast of Johnstown on the site of the old reservoir that was one of the feeders of the Pennsylvania canal. It is the property of a number of wealthy Pittsburg men who constitute the South Fork Fishing and Hunting club. The sheet of water was formerly known as Conemaugh lake. It is from 200 to 300 feet above the level of Johnstown, and is 3½ miles long by 1¼ miles wide, and in some places is 100 feet deep. It is the largest reservoir in the United States. The dam holding the water in check was from 700 to 1,000 feet long, 90 feet thick at the base, 110 feet high, and 20 feet thick at the top. It was inspected monthly by a Pennsylvania railroad engineer.
It is supposed that a cloud burst suddenly added such a volume of water to the immense amount already poured in by swollen streams that the dam could not support the strain.
