General Information: Adobe Creek Reservoir provides quality fishing for several warm water species. Known locally as “Blue Lake”, this reservoir has historically been a favorite for crappie and catfish anglers. As an irrigation storage lake, Blue Lake can experience fluctuation. 2020 water levels have returned to nor-mal upon completion of the dam project. Access road conditions can deteriorate rapidly during rain storms.

Location: Bent and Kiowa Counties, 20 Miles north of Las Animas on County Road 10.

Size: 2,000 - 4,000 surface acres (highly variable), Average Depth 11 ft.

2020 Fishing Forecast Jim Ramsay - Aquatic Biologist

Lamar Service Center

Catfish With the higher water levels in 2020, catfish will be a bit more spread out. However, catfish are very abundant at Blue Lake, especially blue cats in the 16”-18” range. Channel catfish numbers are improving, and large fish over 25” are available. Natural reproduction has benefitted the species through the use of the numerous catfish spawning contain-ers that have been placed and maintained by CPW crews. Both spe-cies (channel and blue) can be readily caught at Blue Lake. Techniques can vary for each species. Channel catfish are primarily bottom feeders while blue cats sometimes prefer a suspended live bait.

Crappie Crappie numbers continue to be very high at Blue Lake. The larger lake size in 2020 may spread these fish out a bit, but anglers should have no trouble locating schools of crappie throughout the lake. Fish in the 10”- 11” range will be the most common, but some 15”+ giant crap-pie are available too. Fishing is expected to be very good in 2020. An-glers can harvest up to 20 fish, but are reminded to obey the posses-sion limit as well. High water boat ramps will be in service to begin the season, but as lake levels drop throughout the summer, boaters can use the low water ramps that are available to the west of the high water ramps.

Walleye/Saugeye Fall sampling showed good numbers of these fish in the 10”- 20” range (see LF table on previous page). Walleyes and saugeyes were mysteri-ously elusive to anglers in 2019. Fish were present in decent numbers, but angler creels tended not to reflect that fact. While some anglers were moderately successful, most anglers were left wondering where the fish had gone. Fishing for walleye/saugeye is expected to improve in 2020, as these fish tend to bite better when lake levels are higher. Boat anglers can be successful slow-trolling worm rigs, walleye-style crank baits, and jigs. Shore anglers can have success casting shad-imitating lures, jerk baits, jigs, and live bait rigs.

White Bass / Wiper Wiper numbers are intentionally kept low at Blue Lake, in favor of the crappie and catfish. Wipers are used to exploit the large gizzard shad population. Shad are very prolific and can produce more forage than can be used by sport fish in a given year. Wipers and white bass (known as “true bass”) are efficient predators and can help keep shad numbers in check. White bass can successfully reproduce at Blue Lake, while wipers are a sterile hybrid. Although relatively low in number, schools of these fish can provide exciting action. Shiny casting lures, shad imitating crank baits, and jigs can provide good results. Bait an-glers favor worms, minnows, shrimp, crawdad tails, or mussels to catch these fish.
