Eyes over Puget Sound

Around once a month, we take to the air and travel by boat to obtain high-resolution aerial photo observations and gather water data at our monitoring stations and state ferry transects. This provides us a visual picture of the health of Puget Sound, which we call Eyes Over Puget Sound or EOPS.

Eyes Over Puget Sound empowers you to:

  • See what is currently happening in Puget Sound.
  • See how weather and climate are shaping Puget Sound water quality.
  • Use Eyes Over Puget Sound as free educational material for your own endeavors.

Surface conditions on our latest flight

Low air temperatures, rain, and late snow accumulation pushed back the discharge of meltwater to Puget Sound this season. The water temperature in Puget Sound was mostly at expected levels, but cooler in South Sound by May. Central Sound saw more oxygenated conditions. This year, La Niña weather made flying for aerial photography challenging, but by June, sunny days made up for it, revealing a high number of schooling fish, unusually low tides, and a glimpse of macroalgae to come. Internal waves in Central Basin and Puget Sound, and the beauty of Puget Sound from the air, are a reminder of the unique place we live in.

While we document water quality issues, we also showcase the natural beauty of Puget Sound.
