Retention Vs Detention Ponds
A Retention Pond: RETAINS water year round.
A Detention Pond: DETAINS water after a heavy rain until it can drain into the ground.
The reason I am making this point is because there is a Market for Aquatic Weed control. A $ 600 under water weed eater can be a money maker. Of course Pond management is a Science by it's self. But with some aquatic Herbicides and algaecide keeping these Retention/Detention clear can be a nice up sell.
But first get an Aquatic Certification, BTW they aren't hard to get.
PS the Big Boys have all the bigger jobs tied up because of the requirements and extra paper work needed for the EPA. Small area don't need that much paper work.
it is one thing to do a off label applications. It is total stupidity to post it on the world wide web and expect people to approve.
