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) are designing experimental placement of fifteen 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.

New Habitat Equals Better Fishing at River Run Park
DTU is actively working with McLaughlin Whitewater Design Group (Merrick & Company), Urban Drainage, and Colorado Parks and Wildlife to design and improve fish habitat downstream of River Run Park. McLaughlin will be redesigning current drop structures in this reach in order to better support recreation and habitat.
These drop structures will include deep pools that more than double the current depth of the river. Each pool will hold cold water throughout the year sustaining DSP Trout during the hot summer months.
The height of the drops will be dramatically reduced and the slope will be decreased improving the potential for fish passage.
DTU is also working with McLaughlin to design L.U.N.K.E.R. Boxes around each drop. Designed to mimic the overhanging banks you might find on the Dream Stream or big Montana Rivers, Lunkers provide fish with a calm place to hang out before striking at food pushed into the pool by the drop structure.

LUNKER BOX ideas and placement suggestions for the DSP River Run Park
When fishing this area in the future keep this in mind. Throwing deep nymphs will help you cover the new depth of the pool, while Wooly Boogers or streamers thrown at the bank and ripped across the pool may entice the big boys out from the box.

Preliminary temperature monitoring results are in.
Full Year Temperature Monitoring chair declares ,”Ha, we do have a trout fishery.”
Whether his pronouncement is shared by others only time will tell, but check out the comparison to the world class trout fishery flowing through Pueblo on an hour by hour basis this August.
DSP vs Pueblo results
UPDATE – Water is flowing into the pond!! Thanks Paul, Alan, Ronnie, Casey and the powers that be !!
With the help of Ronnie’s extensive contact list and fast acting officials, water is again flowing into the pond and will be more closely monitored in the the future. Thanks to all involved.
3/6/ 2016 … Overland Park Pond needs Water.
Who do you call? Help us out? We are trying to find out. … Ronnies call to S.O.B. Save Our Bass.
In July 2014 CPW planted 100 fingerling largemouth bass in Overland Park Pond after the fine restoration of the pond, $15,000 of it funded by Denver Trout Unlimited. We envisioned this great urban pond as a Gateway Fishery for kids. We didn’t envision it drying up. No river water since the Sept 2015. The bass must be gasping. We are down about 2.5 acre-ft or 840,000 gallons.
At present, the Denver South Platte has just one full year temperature monitoring site in Englewood. DTU would like to add at least 6 more to help with the management of this improving fishery.
Check the South Platte Project tab for more information on this project.

Phase 2 from Carson Nature Center downstream toward Reynolds Landing Park
What was a barren construction zone in January 2015 is evolving into a very nice urban fishery in November 2015. The high flows near 3,000 CFS in June-July took some of the topsoil out of areas slated for riparian replanting but all the structure seemed intact and the improved narrowed channels seem to have been retained. Willows planted along the banks in areas have new leaves.
The nicest surprise was the trout feeding along some stretches. More water would definitely help this fishery but the low flow design has obviously worked. Chatfield is putting less than 1 cfs into the Denver South Platte at the moment (11/7/2015.)

Denver Trout Unlimited helped save Carp trapped by construction and falling waters.
DTU Carp Spotting Committee – 15th St bridge over the Denver South Platte -8/3/2015
An estimated 30 Carp and a large turtle were trapped behind the damaged sheet pilings at the Shoemaker Plaza reconstruction site. Efforts convinced authorities that these carp should be saved. Last summer DTU member Trevor Tanner rescued a similar pod of 130 carp trapped by the lowering of Chatfield Reservoir for construction work.
A video of the committee’s visit is on youtube here. ..video

Why DTU believes these Carp should be saved:
The common carp has traditionally been thought of as a “trash” fish in the United States. It turns out most of what is believed about Carp is incorrect and can be traced back to a failed attempt to establish fisheries in the polluted waters of the US in the 1890’s.
Thanks in part to the Carp Slam, fly anglers in Colorado and around the world now see fly fishing for carp in the Denver South Platte as a challenging and exciting opportunity. We’re working as hard as anyone to bring habitat and flows to the Denver South Platte that will easily sustain populations of fish like brown trout and rainbows.
At the same time Denver Trout Unlimited realizes that it will be a long time effort and that a natural healthy river will also sustain Cyprinus carpio from the family Cyprinidae (family Cyprinidae). The Pikeminnow, indigenous to North America, is a member of the same cyprinid family and did coexist with the cutthroats in the Denver South Platte.
