You hear the stocking reports - you think, "Yes! I know they're in there...
let's go!" But how exactly do the fish get from the hatchery to the lakes
or rivers being stocked?
I had the privilege of watching Cherry Creek Reservoir being stocked
with Rainbow trout on June 4, 1999. I asked the Division of Wildlife if
I could observe the procedure and Cindy Regan, of the Chalk Cliffs hatchery,
was very obliging. I waited by the boat ramp on the northwest side of the
reservoir.
The DOW truck arrived at about noon - it's a pretty obvious truck -
big tanks on the bed. The stocker this day is Rod Lane, a DOW employee
for 28 years.
The first thing he does is check the temperature of Cherry Creek Reservoir
where the fish will be released. The water in the reservoir is 61F; the
water in the truck tanks is 58F. It's important the the two temperatures
are very similar - else the fish can go into shock and perhaps have a difficult
time assimilating to their new home.
The pH is also checked to make sure it is similar between tank and
lake or river.
Next Rod opens the the valve and out come the fish!

Today, Rod is releasing 652 lbs. of trout into the water. At an average
2.51 trout per pound, this equates to 1636 fish. And, this all happens
in about one minute! The survival rate of stocked trout is close to 100%.

Here they come! It's a big jump into the reservoir. |

The fish are about ten months old and have been raised at the Chalk
Cliffs Hatchery (west of Buena Vista near the hot springs). Chalk Cliffs
raises about 800,000 trout every year. Stocking of these cold-water fish
takes places between March and July into various places around the state.
Cherry Creek is stocked with Rainbows about every 15 days during the summer.
The warm-water hatcheries also stock the reservoir.

Oooh, I'm stuck! How come I'm always last?  |
When asked if his job is "fun", Mr. Lane responds, "Yes". I think it
would be a pretty fun occupation. Besides stocking, he works at the hatchery
and is a game warden (both hunting and fishing).
