Several large koi have been observed recently in McAleer Creek. Koi are not native to this area, and the ones observed were likely released into the stream intentionally to dispose of them. The release of non-native animals and plants into the general environment can have serious negative consequences for native populations. 

If you observe koi in any of LFP’s streams, the City wants to know 206-368-5440.
