In an effort to prevent the potential spread of quagga mussels, we are advising all boaters who visit Lake Piru to conduct the following measures upon departure of the lake and before entering a another body of water:
1. Inspect all exposed surfaces - small mussels feel like sandpaper to the touch.
2. Wash the hull of each watercraft thoroughly with hot water greater than 140 Fahrenheit.
3. Remove all plants and animal material.
4. Drain all water and dry all areas.
5. Drain and dry the lower outboard unit.
6. Clean and dry all live-wells.
7. Empty and dry any buckets.
8. Dispose of all bait in the trash.
9. Wait 5 days in hot weather and up to 30 days when cool and moist. Keep watercraft dry between launches into different fresh waters.
Additionally, until further notice Lake Piru has suspended its joint AIS tagging program with Castaic and Pyramid Lakes and will not be tagging any vessels leaving Lake Piru. While the potential discovery is unpleasant news, we do not anticipate that it will impact our ability to provide recreation services to the visiting public. As more information becomes available, we will keep our visitors apprised. We apologize for this inconvenience and ask for your help in preventing the spread of invasive species and ask that you aid us in continuing to protect California's water resources. If you have any questions, please contact the Lake Piru Park Services Officer station at (805) 317-8990 or United Water's main office at (805) 525-4431.
