Why Echo Canyon Reservoir 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 Echo Canyon Reservoir, no nutrient or algae measurement meets the evidence bar (at least 3 samples within 10 years).
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 NDEP and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
Echo Canyon Reservoir is a 64-acre lake in Lincoln County, Nevada. Overall water quality is improving over recent sampling years. Limited fish-species data available. Public access is available with 1 public boat landing.
