Little Underwater Neighborhood Keepers Encompassing Rheotatic Salmonids (LUNKER) Pipes.
To solve the problem of lack of habitat shelter from undercut banks, sweeper logs, or big boulders in the Denver South Platte, the DTU River Run Habitat Committee, Ben Neilsen (RiverRun Phase II designer), and Paul Winkle (CPW DSP Aquatic Biologist) have designed and located for experimental placement, of ten 18-36 inch diameter 8 foot sections of concrete pipe with rectangular windows below the water line to simulate the kind of shelter we hope the fish of the DSP will love.
Keep current with our progress here.
Update 11/3/2017. Ben Neilsen, project manager reports:
” The first LUNKER will be installed in the next 3-4 weeks. I’m very excited too about these for a lot of reasons. Particularly I see real promise for reaches that have vegetation restrictions or limitations due to urbanization and flood conveyance. We will vary LUNKER alignments and angle of windows (rotation). “
