Tutka Bay Lagoon, Kachemak Bay State Park

by | Apr 6, 2020

Tutka Bay Lagoon is about 4 miles (6.5 km) inside and on the southwest shore of Tutka Bay in Kachemak Bay State Park, about 15 miles (24 km) south-southeast of Homer and 10 miles (16 km) east of Seldovia, Alaska. Kachemak Bay is considered a critical habitat area with relatively high biodiversity. Kachemak Bay State Park is 400,000 acres (161,943 ha) of mostly wilderness on the southern Kenai Peninsula. The park has no road access and visitors normally fly in or travel by boat from Homer.

Tutka Bay Lagoon is well protected and has depths to 27 feet (8 m), but the entrance is a very narrow channel, and not navigable at low tide. The entrance is also protected by a rock and a submerged delta plain that extends about 0.25 miles (400 m) offshore. About 100 million pink salmon fry are reared in net pens in the lagoon for about 2 months. The fry imprint at the net pens resulting in about 3 million adult pink salmon returning to the lagoon each year.

The Tutka Bay Lagoon Hatchery is owned by the State of Alaska and operated by the Cook Inlet Aquaculture Association. The facility was constructed in 1976 and expanded in 1991. The primary production is pink salmon, which have been released every year from 1976 to 2004, and then again from 2011 to the present. The hatchery is permitted by the State of Alaska to incubate 125 million pink salmon eggs annually. Read more here and here. Explore more of Tutka Bay Lagoon here:

About the background graphic

This ‘warming stripe’ graphic is a visual representation of the change in global temperature from 1850 (top) to 2021 (bottom). Each stripe represents the average global temperature for one year. The average temperature from 1971-2000 is set as the boundary between blue and red. The color scale goes from -0.7°C to +0.7°C. The data are from the UK Met Office HadCRUT4.6 dataset.
