First Full Year DSP Temperature Analysis

First Full Year DSP Temperature Analysis of Denver Trout Unlimited’s 24×7 temperature sensors shows trout friendly water.

Overland Temperatures

Ronnie and Rhys’s trout survive and thrive the short term temperature peaks precisely because they have fish passage, deep pools, shaded structures, cool water seepage, park land irrigation runoff, and the diurnal (day/night) temperature swings. Making sure that trout will have deep pools and shaded structures below the water line is precisely why Denver Trout Unlimited has invested so much time, and effort on studies, meetings, and raising funds for enhanced flows from the Chatfield Environmental Pool.  ...read more

LUNKER pipes are coming.

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.

Keep current with our progress here.

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.

DSP Temperature Monitoring Results are in!

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.

Overland Park Pond needs Water

UPDATE – Water is flowing into the pond!! Thanks Paul, Alan, Ronnie, Casey and the powers that be !!

3/15/2016 5PM

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.

Full Year Temperature Monitoring

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.

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.)
