Heavy winter snowpack and glacial ice in the high Olympics act as a natural reservoir, releasing meltwater gradually through the dry summer months. This sustained, cold runoff keeps the peninsula's rivers flowing year-round even during low-rainfall periods, supporting salmon, downstream forests, and the broader ecosystem that depends on reliable cool water.
Here's a way to think about all that snow piled on the peaks behind you. Those mountains are the peninsula's water tower. Storm after storm packs the high country with snow through the winter, then summer slowly lets it go, feeding the rivers and keeping them cold and running even in the driest months. Without that frozen reservoir overhead, these streams would shrink to a trickle by August. Instead they run full and chilly all summer long, which is exactly what the salmon and the giant trees depend on.
