This spring brought a few Lake Havasu boats through the Malad Inspection Station. Mussel Fouled Watercraft 4, 5, and 6 were all pontoons with varying degrees of biological risk.

💧Mussel Fouled Watercraft #4 spent 90 days in Lake Havasu and had been out of the water for 11 days before it was intercepted by Malad Inspectors. This watercraft had been inspected and decontaminated prior to reaching Idaho. Additional mussels were found deep within the motor mount area and within the chines where they could not be fully removed.

💧Mussel Fouled Watercraft #5 posed significant biological risk having spent 180 days in Lake Havasu with only 1 day out of the water before it reached the Malad Inspection Station. This pontoon had not been captured by any other station on its trip. Mussels were found in the chines and engine area.

💧Mussel Fouled Watercraft #6 was purchased near Lake Havasu and assumed to have been out of the water for approximately 9 months. Malad Inspectors found mussels around the lifting strakes and under the transducer.

🔎 Great job Inspectors!

🔍 Malad Inspectors are at it again with the third catch of the season!

💧 Mussel Fouled Watercraft #3 was a fishing boat that spent the winter in Lake Havasu. The vessel had been out of the water for 3 days by the time it reached the station. Inspectors found multiple small mussels on the trim tabs and gimbal area.

When mussels first settle out, they can be smaller than a grain of rice. How many mussels do you see?

Idaho watercraft inspectors are starting off the 2026 season strong with our first 2 catches of the year.

💧 Mussel Fouled Watercraft #1 was intercepted at the Malad Inspection Station. This boat was in and out of Lake Powell for a few weeks and out for 3 days by the time it arrived at the station. Mussels were found in the bilge area, interior compartments, and carpeted deck tracked in on footwear.

💧 Mussel Fouled Watercraft #2 was intercepted early in the night at the Cedars Inspection Station. This large sailboat had been out of the water for 4 years, but prior to that had spent time in Lake Huron. Mussels were found attached to the keel. Although this vessel poses low biological risk, the introduction of dead mussel material into waterways can skew early detection monitoring results.

Great work Malad and Cedars inspectors! 🔎
