Cate (Shannen Doherty) and her husband Michael (Jason Brooks) have moved to a new house close to a large Michigan lake, one of the many habitats which comes under his control as he leads a small wild life service operation. But it seems they have a major and rather unusual problem on their hands as the lake is full of lampreys which having depleted the indigenous fish stock are now attacking any human which gets near the water. The trouble is that the mayor (Christopher Lloyd) doesn't want Michael kicking up a fuss and warning the general public.
Like a big flashing warning sign "Blood Lake: Attack of the Killer Lampreys" starts with the words "The Asylum presents" and in doing so making it very clear what sort of movie you are about to watch. In truth you should already know what sort of movie you are about to watch as the title "Blood Lake: Attack of the Killer Lampreys" should scream out poor movie long before you have even started watching it.
And "Blood Lake: Attack of the Killer Lampreys" is every bit as bad as you probably imagine it to be. The storyline does nothing new; killer creatures in a lake, girls in bikinis, a mayor who won't put out warnings, the hero in authority trying to protect the community. I shouldn't need to say this but think "Jaws" but with sharks switched out for lampreys which in fairness is a little bit creative. That in truth is what this movie is all about, the creativity of people dying by lamprey and it is clear that those behind the movie put more emphasis on how people could die by lamprey although the less than convincing special effects make many of these death scenes expectedly weak.
What this all boils down to is that "Blood Lake: Attack of the Killer Lampreys" is a poor movie but in truth no worse than I imagined it to be when I saw the title and saw who the production company was. Unfortunately it isn't one of those entertainingly bad movies and just one you regret wasting your time on.
