Invasive species like Quagga and Zebra mussels and New Zealand Mud Snails are spreading at a rapid clip to lakes and streams throughout the West, and because of the threat these non-native critters pose to our water ways, you may soon find launching at your favorite lake more of a logistical hassle than ever before.

Local authorities are taking the threat very seriously, as these invaders are a really bad deal. In short, they are filter feeders which can completely alter entire ecosystems by removing phytoplankton from waterways — the stuff from which all other life begins. Also, they clear up the water, allowing sunlight to penetrate deeper, causing a proliferation of aquatic plants that can change species dominance.

To battle these guys, some lakes have completely banned all outside watercraft, while many others are requiring increasingly thorough inspections before you launch. Take one of my favorite fishing spots for example, Lake Tahoe. There, you have to pay for a complete inspection prior to launch (it was $30 for my little 14-foot skiff). Click here to read more…
