the term "infested" implies something that decreases property value.
if the lake were full of trout, which might increase property value if uncontaminated and fish-able, a word that implies an increase in property value could be "brimming" or "flush" (e.g. "I am flush with ocelots" -3rd rock from the sun, beanie babies episode)

While the word 'infested', which was obviously ill-chosen, does convey notions of contamination et al, the eel-like sea lamprey could someday enable paralyzed people to reliably control their legs.
You see, the creature has a removable spine that can remain alive in a dish and be stimulated to move as if it's still inside a swimming animal. It is possible to transplant the spinal chord into a human being and control the signals via outside controls, thereby enabling the paralyzed individual to move.
This is a veritable medical miracle which must be worth millions. It is obvious to me that the lake containing these wonderous creatures would easily be considered the more valuable of the two.

Question 1: The correct answer is False.
Since sea lamprey are nuisance species that are likely to harm native species, their presence in your lake will decrease your property value.

False
These organisms were a major cause of the collapse of lake trout, whitefish, and chub populations in the Great Lakes during the 1940's and 1950's

European, as the Sea Lamprey (Petromyzon marinus) existed in the Atlantic ocean, prior to discovery in the Great Lakes in 1835...
