What is changing
Cedar Lake?

A source-traceable examination of Cedar Lake's low water levels, the regulatory status of six Coffee-affiliated dams, and the competing hydrologic explanations.

THE CENTRAL QUESTION

Two questions.
One lake.

The evidence supports a real regulatory dispute. It does not yet provide an independently reproducible answer to how much the upstream dams changed Cedar Lake's inflow.

01

Regulatory compliance

Were the dams properly authorized, inspected and maintained?

Verified
02

Hydrologic causation

How many acre-feet would have reached Cedar Lake without Dams 5 and 6?

Disputed
COMPETING EXPLANATIONS

The claims do not yet reconcile.

OWRB POSITIONReported
“No evidence” the Coffee dams caused the lake or well decline.

Reporting says the agency emphasizes drought, evaporation, limited natural inflow, discontinued supplemental groundwater use and declining groundwater.

O
Oklahoma Water Resources BoardFull investigation requested
VS
JOHNSON-BECKER POSITIONReported
Dams 5 and 6 are the primary cause because they intercept two principal tributaries.

The published StreamStats analysis assigns 141.4 acres to Dam 5 and 188.8 acres to Dam 6—roughly 330 acres, or about 39% of the 853-acre watershed. It reports 3.5 AF and 71.2 AF of normal storage, respectively.

Johnson-Becker, LLCPublished method and figures available
Independent drainage-area cross-check

The applicant-side February 2026 H&H report models about 201 acres draining to Dam 6; Johnson-Becker reports 188.8 acres. The close figures strengthen the drainage-area estimate, but do not by themselves quantify lost Cedar Lake inflow.

What would resolve causation

A calibrated water balance comparing wet, normal and drought conditions with and without Dams 5 and 6.

STRUCTURE REGISTER

Seven verified IDs.

CHRONOLOGY

The record over time.

Dates marked reported await direct confirmation from the underlying primary files.

OWRB's published inventory lists Cedar Lake Dam completed in 1959 and the owner as Western Sportsman Club.

Verified

A gypsum-related subsurface event reportedly drained the lake rapidly.

Reported

Supplemental groundwater pumping reportedly ceased.

Reported

Coffee Dam 5 reportedly completed.

Reported

Coffee Dam 6 reportedly completed; Cedar Lake Dam breach also reported.

Reported

Anonymous complaint prompts OWRB review of an upstream dam.

OWRB RECORDS PRODUCTION

The production is indexed.
Material gaps remain.

OWRB responded to Web Inquiry 3078 on August 31, 2026 at 12:54 PM Central with a Box production and stated that it contained all requested Cedar Lake and Coffee-dam information. Review of the 103 PDFs found substantial complaint, dam-safety, engineering and water-application records, but did not locate several expressly requested categories. Production completeness remains under review.

BOX PRODUCTION 103 PDFs · 86 unique

A completeness follow-up to Web Inquiry 3078 listed twelve items: five categories not located in the August 31 production, three only partly represented, and four procedural items bearing on the September 15, 2026 Board meeting. OWRB replied at 1:21 PM CT that it would resend the Cedar Lake presentation through Box. The reply did not provide an item-by-item answer to the twelve items.

ITEM-BY-ITEM ANSWERNone providedReported

Reported A 72-slide file titled Cedar_Lake_presentation_8_13_2026_Final for public release.pptx (69 visible slides) has been adopted by this project as an OWRB records-production item delivered through Box in response to Web Inquiries 3078 and 3081; its contents are attributed to OWRB. Archive inventory listing is pending. Byte identity with Box file 2406118218844, version v4 as served on September 1, 2026 at 18:49 CDT, was verified against the project copy: 96,667,666 bytes and local SHA-256 651c1e4713b5493593166294ecf6d6f26ea1b195dde16811e83756b75fd65f4a. Whether this is the approximately 69-page investigation requested under item 1 has not been established. The presentation's substantive statements have not been independently reproduced, and its contents are not republished here. On September 2, 2026, a domain-authenticated OWRB Public Information response to Web Inquiry 3086 stated that the presentation is not for distribution in any individual slide or in its entirety and that the project's clarification had been forwarded to OWRB's legal department for further review. The response did not state a legal or policy basis for the asserted restriction. The filename is the file's own and does not itself establish official public-release authorization.

Additional records activity · September 2–10, 2026

Reported On September 2, the project completed an OWRB web-form interaction for Cedar Lake Dam (OK11073) structural and engineering records and two ODEQ Central Records form interactions concerning Clean Water Act §401 and related surface-water records and Cedar Lake-area well and laboratory records. A completion page appeared after each form. A form completion page confirms only the recorded browser interaction; it does not establish agency intake or processing. ODEQ Central Records later responded on September 10, requesting date-range clarification and referring the complaint-record search to its Environmental Complaints and Local Services Division. The response confirms receipt and routing only.

On September 3, OWRB responded under Web Inquiry 3090 and provided a Box folder containing 29 PDFs. The project verified that all 29 were byte-identical to files already present in the August 31 Coffee Dam production. Review of extracted text and full-page OCR covering all 131 pages located no record responsive to the eleven numbered OK11073 categories within that review scope. This does not establish that OWRB has no responsive records: OWRB supplied no item-by-item disposition, and agency holdings outside the delivered set remain unknown.

Also on September 3, the project sent six preliminary records-location or routing inquiries to EPA Region 6, USDA Natural Resources Conservation Service in Oklahoma, two local conservation districts, and the Canadian County Clerk and Assessor. EPA Region 6 responded on September 10 that locating the requested EPA records would require a formal FOIA request. This confirms EPA receipt and routing only; it does not establish responsive records, federal jurisdiction, or a permit requirement. No formal federal FOIA request or fee was authorized.

NEXT GATEObtain OWRB legal review's item-by-item disposition of the September 1 completeness follow-up, the basis and scope of the presentation-distribution restriction, and OWRB's item-by-item disposition of Inquiry 3090. Monitor the other government lanes for delivery failures, acknowledgments, fee estimates, or substantive responses. No fee is authorized without separate approval.

CONTROLLING SOURCES

Follow the record.

These documents consolidate the source trail and state what remains unresolved.

OWRB response to Web Inquiry 3078 · August 31, 2026

The Box production contains 103 PDFs representing 86 unique files after hash-based duplicate control, totaling 203.4 MB. OWRB represented that it contained all requested information. Review verifies all six Coffee dam IDs and substantial regulatory material, but did not locate the complete Cedar Lake investigation, underlying datasets, complete well-testing package, complete consent-order materials, or Cedar Lake water-right history.
