What the OWRB production establishes
This review concerns an earlier records production received before the separate August 31 follow-up request. It materially improves the regulatory and dam-condition record, but does not supply a reproducible answer to how much Dams 5 and 6 changed Cedar Lake inflow.
Verified scope
Six dam IDs resolved
OWRB records identify Coffee Dams 1-6 as OK30688, OK30689, OK30690, OK30691, OK30692 and OK30686. Cedar Lake Dam is OK11073.

OWRB measurements and condition observations
- Dam 1 · OK30688: 40 ft · 216 AF maximum storage · fair condition
- Dam 2 · OK30689: 29 ft · 205.1 AF maximum storage · poor condition
- Dam 3 · OK30690: 27 ft · 89 AF maximum storage · fair condition
- Dam 4 · OK30691: 18 ft · 64.1 AF maximum storage · poor condition
- Dam 5 · OK30692: Poor condition; OWRB describes it as directly upstream of Cedar Lake Dam
- Dam 6 · OK30686: 33 ft · 119 AF maximum storage · fair condition; no application or valid permit found at the June 2025 inspection
Measurements are OWRB approximations derived from site survey and available LiDAR unless otherwise noted. Condition ratings describe the inspection date, not current condition.
Jurisdiction and compliance
All six were treated as jurisdictional
The June 2025 Dam 6 warning and November 2025 Dams 1-5 notice state that the structures met jurisdictional size thresholds. OWRB required a construction application for Dam 6 and applications for Dams 1-3; it requested Statements of Assurances for Dams 4-5.
Water rights
Five applications in the production
Files are present for 2026-0010 (Dam 6, C&F Ranch LC) and 2026-0012 through 2026-0015 (Dams 1-4, Coffee Grounds LLC). Production filenames describe them as pending. Dam 5's assurance was said by OWRB correspondence to require an associated stream-water application, but no Dam 5 application file appears in this production.
Engineering
Dam 6 drainage areas closely align
The production includes Dam 6 application forms, plans, H&H reports, a variance request and review correspondence. A February 2026 applicant-side H&H report models a 201-acre drainage area; Johnson-Becker's published StreamStats analysis reports 188.8 acres. The values are within about 6%, corroborating scale but not proving downstream causation.
Flow statement
A party statement, not measured streamflow
May 2026 correspondence says Pond 6 remained full and passed spring flow through its drain, while also stating that no streamflow estimate or filling history was available. This is a filed party statement and does not replace monitored inflow, storage, release or downstream-flow data.
Material omissions
What the production does not resolve
- The complete approximately 69-page Cedar Lake investigation and its appendices
- Underlying lake-stage, precipitation, evaporation, seepage, groundwater and calibrated water-balance files
- The complete 82-well laboratory package, QA/QC and chain-of-custody records
- A complete Dam 5 stream-water application file
- The referenced completed Dam 6 breach analysis
- Complete current compliance histories and final dispositions for all dam and water-right applications
- A verified reconciliation of the identical coordinates on the Dam 4 and Dam 5 assurance forms
Decision boundary
What this review does not conclude
The production verifies regulatory actions, identifiers, inspection observations and application activity. It does not establish current legal ownership, prove that a condition persists today, determine legal liability, or quantify Cedar Lake inflow with and without Dams 5 and 6. Hydrologic causation remains disputed pending the missing data and independent professional analysis.
