Where a listing names its water source — spring-fed, dam-released, tidal — that source tells you more about temperature and current than the category does.
Recent rain matters for anything moving and matters less for anything still.
In Washington, the Washington State Department of Health publishes the water-quality and algal-bloom advisories that apply to these waters. Check them alongside the live gauge data rather than instead of it.
Scout depth and current from the bank before entering anywhere unfamiliar, and enter feet-first the first time.
Assume no lifeguard, no cell signal, and a long response time.
Check posted signage for swimming bans — these are often the sites where legal status is least obvious.
Cascade rivers are cold enough for cold-water shock on the hottest days of the year, and drownings cluster on the first hot weekend of summer when the water is still at snowmelt temperature. Olympic hot springs have had closures for bacteria.
Cold water deserves more respect than most swimmers give it. The National Weather Service notes that cold shock can be as severe at 50-60°F as at 35°F, and that the involuntary gasp reflex can be triggered by water as warm as 77°F — which is why entering slowly matters even on a hot day.

Olympic hot springs have had closures for bacteria.
Generally no, not straight away. Runoff raises the current, pushes new debris into familiar pools, and spikes bacteria counts. Give moving water 24 to 48 hours to clear after heavy rain.
