No public gauge reports the water level at Lake Cushman, so this page shows no level chart. We would rather leave the figure out than publish an estimate that nobody measured. Local marinas and park offices usually know the current state of the water better than any feed.
If the water looks like pea soup or paint, stay out and report it to the managing agency. Water temperature is not measured at this lake by any public agency we read. Swimming season in Washington runs through the warm months, and day-use areas set their own opening dates.
