Sportfishing Notes Walleye and Saugeye
Fish the dam during early
spring when the water
temperature is 40-50°F.
Boat anglers do well jig-
ging, trolling or casting
shad raps, and trolling wally
divers during late spring
and early summer.
Fish rocky areas, drop-offs,
and flats in each arm of the
reservoir at other times.
Wiper
Fish the inlet when the
reservoir is filling and fish
open water at other times.
Fish are often found chasing
shad, so use shad imitations
and follow the seagulls.
Green mussels as bait work
well.
Channel catfish
Fish coves and reservoir
arms, especially during
August and September.
Cut shad, cut carp, and
shrimp as bait work well.

North Sterling Reservoir, once known as Point of Rocks Reservoir, was built by the Empire Construction
Company between 1909 and 1911, making the reservoir approximately 105 years old. Water used to fill
North Sterling Reservoir is taken from the South Platte River near the town of Snyder, and flows down a
62-mile long earthen canal before reaching the reservoir. Due to water breeching the inlet canal in several
places, the reservoir was not filled until 1912. The reservoir was stocked with black bass and yellow perch
before it officially opened in 1913. In 1915, black crappie were also stocked.
Since the primary function of North Sterling Reservoir is to store irrigation water, water levels routinely
drop during the irrigation season. During a typical year, water levels can fluctuate by approximately 40 ft,
reducing the reservoir’s volume to about one-seventh of its capacity (Figure 1). Unfortunately, the reservoir
is drawn down while panfish are spawning, limiting
recruitment of critical prey species such as bluegill and
gizzard shad. These young fish seek refuge in
littoral habitat, but this habitat is lost as the water
level begins to drop, increasing their vulnerability
to predation. The risk of being consumed is heightened
as the water level continues to drop and fish are concentrated into a successively smaller
pool. Young fish of other species such as walleye, saugeye, wiper, and crappie are also
negatively impacted by reservoir draw down.

In 2012, the reservoir’s water level was drastically reduced
due to severe drought conditions. The low water level, in
combination with decaying organic matter from an earlier
blue-green algae bloom, created a perfect storm that re-
sulted in a mid-September fish kill. High winds turned the
reservoir over, forcing decaying organic matter from the
bottom of the lake up to the top of the water column, deple-

Wildlife crews found at
least one fish of every spe-
cies that inhabits the reser-
voir dead along the shore-
line. Though the reservoir
did not suffer a complete
fish kill, catch-per-unit-
effort decreased by 80%
from the 2011 to 2012 an-
nual survey (Table 1).
While some primary
predators such as walleye
were not drastically effect-
ed by the partial summerkill,
other primary predators
such as wiper were (Table 1).
While it was terrible to lose
so many predatory sportfish,
the loss allowed panfish spe-
cies to flourish (Table 1),
which has helped create ex-
cellent black crappie, white
crappie, yellow perch and
bluegill fisheries.

in low numbers, other species (e.g., bluegill and channel catfish) are routinely caught during annual surveys, indicating
the 2012 fish kill negatively affected these species among others.

FISH SURVEY AND MANAGEMENT DATA Mandi Brandt - Aquatic Biologist (Brush)
As in many of Colorado’s reser-
voirs, gizzard shad are relied upon
as the primary prey species for
sportfish in North Sterling Reser-
voir because the species is a broad-
cast spawner and is highly prolific
(250,000 eggs per female). Unfortu-
nately, there was extremely poor
gizzard shad recruitment in the
reservoir in 2006, 2007, and 2008
(Figure 2), leaving sportfish in
poor condition.
Reservoir draw down, winterkill,
and nutrient inadequacies are re-
sponsible for the lack of recruit-
ment. Large drawn downs oc-
curred in 2005 and 2006. In 2006,
the reservoir was substantially drawn down during the irrigation season due to severe drought, resulting in
a very low pool level during the winter. Gizzard shad could not withstand the poor water quality in the pool
and succumbed to winterkill, leaving extremely low numbers of adults in 2007 and 2008 to produce young
fish. Even if young gizzard shad were produced, the zooplankton prey base would not have been large
enough at the time to support the gizzard shad. Relatively small numbers of zooplankton were available to
eat, likely due to low levels of
nutrients that would normally
support phytoplankton, which
would in turn support zoo-
plankton.
In an effort to re-establish the
reservoir’s gizzard shad popu-
lation, crews from the former
Division of Wildlife initiated a
shoreline grass seeding project
and an adult gizzard shad
stocking program. In 2009 and
2010 crews seeded shorelines
with Japanese millet and annual
rye to return nutrients that
were locked up in the reser-
voir’s soil to the water column.
About the Grass Seeding Project...
North Sterling Reservoir LAST UPDATED: JANUARY 2016
FISH SURVEY AND MANAGEMENT DATA Mandi Brandt - Aquatic Biologist (Brush)
About the Fish... The idea behind shoreline seeding is that as the grass grows, it
takes up nutrients from the soil. Then, when the grass is inun-
dated by water it is killed and these nutrients are released into the
water column where they are available to phytoplankton. This
creates a positive bottom-up effect in the food-web in which more
nutrients are available to support more phytoplankton, which in
turn can support more zooplankton, which in turn can support
more gizzard shad, which in turn can support more sportfish.
In addition to seeding shorelines, crews began an adult gizzard shad stocking program. Approximately 700
adult gizzard shad have been stocked into the reservoir since the spring of 2009. As hoped, the gizzard shad
spawned and substantial recruitment returned in 2009 through 2011, supplying sportfish with a much
needed prey base (Figure 2). Unfortunately, the gizzard shad population took a severe hit during the 2012
fish kill (Table 1; Figure 2). While the fish kill initially resulted in the loss of gizzard shad, the gizzard shad
population expanded due to less predatory pressure from species such as wiper (Table 1; Figure 2). In 2014
and 2015 the walleye and saugeye populations flourished on the robust gizzard shad prey base, which has
caused the pendulum to swing yet again, resulting in a low catch of gizzard shad during the 2015 annual
survey (Table 2; Figures 2-3).
Gizzard shad
Figure 2. Gizzard shad catch-per-unit-
effort (CPUE) during the 2005 to 2015 an-
nual surveys at North Sterling Reservoir.
For comparative purposes, the number of
fish collected was standardized per gillnet.
Severe draw downs in 2005 and 2006, fol-
lowed by a gizzard shad winterkill in the
winter of 2006, led to poor recruitment in
2007 and 2008. Recruitment rebounded in
2009 through 2011 as a result of shoreline
grass seeding and adult gizzard shad
stocking. Gizzard shad CPUE was drasti-
cally reduced again in 2012 since a large
portion of the population died during the
fish kill. The loss of predatory fish during
the fish kill allowed the gizzard shad
population to rebound in 2013 and 2014,
increasing CPUE. However, the gizzard
shad population supported enough preda-
tors in 2014 and 2015 to consume most of
the gizzard shad by the 2015 annual sur-
vey.

FISH SURVEY AND MANAGEMENT DATA Mandi Brandt - Aquatic Biologist (Brush)
Walleye and saugeye Walleye were first stocked in 1949, and were one of the species that made North Sterling Reservoir one of
Colorado’s premier warmwater fisheries during the 1970s. During the early 1980s rough fish (common
carp and river carpsucker) all but overtook the reservoir. To improve the fishery, the reservoir was chemi-
cally reclaimed by the former Colorado Division of Wildlife in 1985. Many efforts were made during the
late 1980s and 1990s to rebuild the walleye fishery; however, it never bounced back to its former self,
partly due to the introduction of wiper. In 2004, crews tried once again to build a premier walleye and
saugeye fishery by drastically increasing fry and fingerling stocking rates. Since that time, nearly 46.6 mil-
lion walleye and saugeye have been stocked into North Sterling Reservoir. Though annual surveys from
2005 to 2009 yielded extremely low numbers of walleye and saugeye, the 2010 and 2011 surveys indicated
walleye and saugeye were on their way to making a comeback before the 2012 fish kill (Figure 3). Fortu-
nately, the fish kill had a relatively small impact on these two species, as opposed to wiper (Figures 3 and
5). By 2013, the size of the walleye population surpassed the populations of the 1970s that made North Ster-
ling a premier warmwater reservoir (Figure 3). The average number (52) of walleye and saugeye caught
per gillnet in 2015 is the highest recorded catch in history for North Sterling Reservoir (Table 2; Figure 3).
This catch is currently the third largest in the state, following 123 and 89 per net at Jumbo Reservoir and
Jackson Reservoir, respectively. Walleye and saugeye caught during the 2015 annual survey were in excel-
lent condition (Figure 4). Walleye were 14.85” and 1.42lbs on average, with the largest (walleye) measuring
27.32” and weighing 8.87 lbs (Table 2; Figures 3-4). Walleye and saugeye fishing was excellent during 2015,
and based on the number
and sizes of walleye and
saugeye caught during
the 2015 annual sample,
should be even better
during the 2016 fishing
season.

Wiper Though catch rates of wiper were generally higher
than those of walleye and saugeye during the 2005 to
2009 annual surveys, wiper abundance was relatively
low through these years (Figures 4-5). Abundance
really dropped in 2009 through 2011 because fewer
wiper were stocked to decrease predatory pressure
while efforts were made to re-establish the gizzard
shad prey base (Figure 5). Only one wiper (20.9” and
4.6 lbs) was caught during the 2012 annual survey,
indicating the wiper population took a substantial hit during the 2012 fish kill (Table 1; Figure 5). As ex-
pected, the gizzard shad population had a positive response to the loss of predators resulting from the fish
kill (Figure 2). It was felt the gizzard shad prey base could support more predatory fish; thus, substantial
numbers of wiper were stocked into the reservoir in 2013-2015. Annual surveys indicated that some of these
wiper survived in 2013, but not in 2014 or 2015 (Tables 1-2; Figure 5). The survival of this young age-class
of fish is vitally important because these fish will help form the future wiper population. Without their sur-
vival, the population, which was composed of older age-classes in recent years, would eventually disappear
(Figure 5). Though the majority of anglers target wiper at North Sterling Reservoir (Figure 9), the species
has had little success in recent years. Although efforts will be made to re-establish a wiper population, fu-
ture predatory management will primarily
focus on walleye and saugeye, which have
proved to provide an excellent fishery in
recent years.

Crappie (black and white) Though it was terrible to lose so many preda-
tory sportfish during the 2012 fish kill, the loss allowed
panfish species such black crappie and white crappie
to flourish (Tables 1-2). In fact, crappie catch-per-unit-
effort was 15 times higher in the 2013 annual survey
than it was in the 2012 annual survey (Table 1). Based
on the crappie caught during the 2015 annual survey,
anglers can expect excellent fishing during the 2016
season (Table 2; Figure 6). In addition to good num-
bers of quality-sized (8-10”) crappie, anglers will have
the opportunity to catch several preferred- (10-12”)
and memorable-sized (12-15”) fish (Figure 6). Trophy-
sized (>15”) crappie are undoubtedly lurking in the
reservoir. Catch rates for stock-sized (5-8”) crappie
should also be high (Figure 6).

About the Fish... Channel catfish Approximately 428,000 channel catfish
have been stocked since 2004. Regard-
less of stocking rates, low numbers of
channel catfish are sampled in nets dur-
ing annual surveys. The 11 channel cat-
fish sampled during the 2015 annual
survey were 17.93” long and weighed
2.37 lbs on average, with the largest fish
measuring 24.33” and weighing 5.63 lbs
(Table 2). Though few channel catfish
are typically caught in nets, the lower
numbers of fish caught in 2012 and 2013
compared to 2011 indicate the 2012 fish
kill negatively impacted the channel
catfish population (Table 1). Despite
this negative impact, fishing for channel
catfish was good during 2015. In an ef-
fort to gain a better understanding of the channel catfish population, a catfish project was performed in
2015. Results from this project indicated that the channel catfish population is composed of several size
classes, and that there is a large number of fish 17-23” long (Figures 7-8). The largest fish caught during the
project measured 36.26” and weighed 24.10lbs. Channel catfish fishing should be great during the 2016
fishing season.

About the Anglers...
2011 North Sterling Reservoir creel survey According to the 2011 creel survey, almost
6,200 anglers fished North Sterling Reservoir
for nearly 21,000 hours between May and
September of 2011 (Table 2). Ninety-eight
percent of anglers were Colorado residents,
of which 42% were from nearby towns in the
six surrounding counties (Logan, Sedgwick,
Phillips, Yuma, Washington, and Morgan).
Non-resident anglers were from Nebraska,
Wyoming, Utah, California, Minnesota,
and Michigan. The majority of anglers
fished with bait (75%), followed by
lures (14%), or a combination of
the two (10%). The remainder of
anglers fished with flies. Over one-
half of anglers targeted wiper
(Figure 11). Walleye and saugeye
were also highly sought after (Figure
11). Nearly 17,500 fish (all species
included) were caught, of which
approximately 43% were kept
and 57% were released. In
general, most anglers
enjoyed their fishing
trips at North
Sterling
Reservoir,
ranking their trip
quality as either
excellent (11%), good
(40%), or average (31%).
Likewise, most anglers approved of the fish they caught,
ranking fish quality as either excellent (22%), good
(56%), or average ( 21%).
