Controlling Invasive Species
There are many ways to control invasive species but the best method is to prevent them from entering your lake. Control methods are categorized into three groups (see below), each having their own set of tools and methods.

Chemical Control - Using pesticides, herbicides, or fungicides can be effectively used to kill invasive species, but it can be problematic due to impacts on non-target organisms, including humans. Prolonged use of chemical control is expensive, and may be ineffective when target organisms evolve resistance to certain chemicals.

Mechanical Control - Physically removing the invasive species or changing habitat conditions is often successful, but can be expensive and labor intensive. Modifying habitat conditions, through alteration of fire or flooding regimes is a mechanical control option when removal is infeasible.

Biological Control - Introducing a natural enemy (predator or parasite) generally from the invader’s native range is often the only alternative for controlling an invasive species that has established dense populations over large areas. It can be an environmentally sound way to control invasive species with minimal expense, but some control agents do not survive and others attack non-target organisms.

Note: The methods above have many advantages and disadvantages, each one having an adverse affect on the other, so it is very important that you perform the proper research and choose the best method for your environment.
