From September through October, 2013, over 100 volunteer citizen scientists were engaged in Salmon Blitz. Armed with minnow traps, GPS units, waterproof cameras, datasheets and other tools for assessing water quality, these volunteers caught, identified, and tallied local fish species in streams in Glennallen, Cordova and on the Copper River Delta. Their data will be used to generate nominations for habitat to be added to the Anadromous Waters Catalog (AWC).
Surveys will be continued through 2016. Contact CRWP for more information, to volunteer, or to discuss potential sites for conducting surveys.
The following table summarizes results so far:

|Cumulative length of new streams to be nominated to AWC (miles)||2.1||1.7||2.1|
|Area of new lakes nominated (sq. miles)||n/a||n/a||0.05|
|Increased upstream extent for listed species (miles)||2.1||1.7||2.1|

Types of Fish Found
The following are pictures of the different types of fish that were found during surveys.
Coho salmon were the most abundant fish caught around Cordova and are the targeted species for downriver surveys.
Chinook, or king, salmon primarily spawn in the upper reaches of the watershed, so it is expected we will only find rearing Chinook fry in upriver surveys. They are the targeted species due to declining Chinook runs.
Sockeye, or red, salmon primarily rear in ponds, so it was a surprise to find this sockeye fry during one of our stream surveys in Cordova!
Dolly Varden were found in most coho streams.
Cutthroat trout are mostly found in swifter, shallower coastal streams.
Sculpin were found in coastal streams. Sticklebacks were abundant in wetlands and ponds.
Arctic grayling are only found in the upper part of the watershed. This specimen was found in Dry Creek by the Glennallen 5th grade class.
Longnose suckers were also only found in the upper part of the watershed. Only one burbot was caught during surveys. This specimen was found in a tributary of the Copper River south of Gakona.
