I can't help you with the fishing part, cause I haven't fished out there yet this year, but as far as lillies, I pass over Henderson a few times a week and WLF have been out there spraying and they're not as bad as they were a month or so ago.
I see quite a few boats have been launcing at Butte LaRose, so it shouldn't be a problem.
The Lilly pads are bad u can dock at any private landing all around the interstate is full of Lilly pads. Water is muddy in some areas due to a pipe line being put in north of the interstate. I was on water lastnight frogging.
which one are you talking about here? Usually lily pads are just starting to come up this time of year?
Water hyacinth are a free-floating perennial aquatic plant native to tropical and sub-tropical South America.They are an invasive species and have been screwing up our water ways for years. See top pic.
Lily Pads are native to louisiana and sprout up during the warmer months and die off during the winter. they help control water temp and prevent overgrowth of subsurface grass such as coontail and hydrilla by blocking out the sun. They are a great thing to have around. See middle pic.
Giant Salvinia is the other extremely problematic aquatic invader we have choking out our water ways. they are kind of like super duckweed or mini water hyacinths. in many ways they cause more harm than water hyacinths. See bottom pic
