Why Lake Chickasha has no grade

We grade a lake only when the monitoring record supports a letter: at least three phosphorus or chlorophyll-a samples in the last ten years, scored against EPA National Lakes Assessment thresholds for this lake’s ecoregion. For Lake Chickasha, the only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. Sampling here has recorded water clarity and phosphorus, but not algae (chlorophyll-a).

Not Rated is not an F. It is EPA Integrated Reporting Category 3 — insufficient information. The water here may be excellent or poor; nobody has measured enough of it to say. Everything below that has been measured is still reported on this page.

Sampling is run by ODEQ and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.

Lake Chickasha is a 820-acre lake in Caddo County, Oklahoma with an estimated average depth of about 63 feet. Water clarity is improving over recent sampling years. Limited fish-species data available. Public access is available with 3 public boat landings.
