To help struggling salmon populations, the state of Washington is legally required to replace hundreds of culverts that divert streams under roadways. The state transportation department is replacing old, rusting metal pipes with broad, concrete promenades that provide more gradual gradients and gentler flows for salmon swimming upstream to access more spawning grounds. The full scope of the effort will last 17 years and cost $3.8 billion.

How much can you really learn from a dead herring in a jar? Housed in the UW College of the Environment, the Burke Museum’s Ichthyology Collection is home to more than 13 million preserved fish specimens from around the world, many dating back over a century. By far the largest collection of its kind in North America, it includes over 300 different samples of Pacific herring — an ideal species for researchers aiming to look back in time.
