Invasive Species kayak care

We don't have any EBMUD inspections on launches up this way. But growing up near those lakes, I've grown used to the idea of boat inspections and regular care to prevent invasive species while lake hopping.
Most of my lake hopping is done in the summer, as winter limits my options and mobility and I tended to hit the same 2 or 3 stomping grounds, often a week apart due to work. During the summer, my hose outside in the Redding heat stays hot to the touch all day long and steams when I spray it in the shade. Even poached an egg with it as an experiment (this heat is gunna be killer next week). I'm sure it's close to the 140F water required in some lakes to prevent mussels. I also keep my kayak to air dry with hatches open in the 100+F norcal heat but in the shade of my patio after powerwashing it down inside and out. But sometimes I'm doing back to back lake binges, often 100+ miles apart. I haven't been as religious on washing my auxiliary gear like paddles and transducer and tackle.

I don't want to be the guy that brings invasive species. Any tips to mitigate risk?

My PA takes on small amounts of water via the 360 gear hole in the pedal well. I carry a pump to pump the kayak out before leaving the lake, and then on its return to the garage, will pop the hatch covers to ensure the interior of the hull dries completely.

Having lived in Redding for years I can attest to the heat, you are pretty safe due to the ambient temps in your storage area. Frequency of use can be an issue which is why I pop the hatches on my boat. Being retired I have the luxury of fishing multiple times a week and the boat may not have time to dry completely between trips (hence the extra diligence I use).

After fishing I set a fan on top of the front hatch blowing air into the hull and open the hatch in the middle (on my newer outback) or the rear (older outback) to let the air out. Everything, including my pool noodles, are dry the next day.

The Oregon Department of Fish and Wildlife suggest using Formula 409 as a quick, effective way to kill invasive species larvae.

From a 2014 USFS technical report on invasive species control: "...much of research for their effectiveness against aquatic invasive species has focused so far on one of the alkyl dimethyl benzylammonium chlorides, abbreviated as ADBAC, the active ingredient in Formula 409®. Formula 409® was selected to test against whirling disease and New Zealand mudsnails..." and was proven effective for most invasive species in an aquatic environments, but found to not be practical for terrestrial envirnments.

Sorry, they didn't include recommendations for how to use it.  I just spray it everywhere on my kayaks, scrub it in, let it set for a moment, then rinse everything.

I think the main consideration is to be extremely vigilant if you fish in a lake, or river that has an infestation. So far California does not have many areas in the north where they are located. Here is  a list of the areas of concern:

And here are the most recent new areas:

Also, the larva are microscopic so when your kayak, or other vessel is being inspected they are only looking for water. If they find even a tiny amount you are sent on your way back home.

I store my boat upside down with hatches open. I insert a desk fan to move the air about.

Kudos for doing what you can.
