| A Survey and Analysis of Fishing Parameters of the Ozark Fly Fishers for Bennett Spring, Saturday, November 11, 2000
SUMMARY: Ozark Fly Fishers were surveyed at the annual Bennett Spring "Catch and Release" outing, Saturday, November 11 regarding fishing techniques, lures and flies used and fishing success to establish a database for future reference and analysis. the most successful lures/flies used were the woolly bugger, crackle-back and midge. Crackle-backs and Midges were fished on a 7X tippet (2.5 pound test) slightly below the surface by stripping or dead drifting.
PURPOSE: The purpose of this survey was to establish a database of fishing observations from Ozark Fly Fishers, fishing during the annual "Catch and Release" outing to analyze for future fishing activities.
INTRODUCTION: Fly Anglers frequently ask "what's the best lure or fly; what weight leader; what is the best technique, how many fish did you catch, and how large were the fish you caught." To answer some of these questions and establish an information database, I surveyed 37 Ozark Fly Fishers at our annual outing. The information included lure/fly used; number of trout caught during the day; largest trout; fly presentation and water depth the fly was fished; as well as meteorological information and water conditions. The information gathered was used to establish a baseline database to be added to at future catch and release outings. Analysis of the information will help anglers new to catch and release fishing at Missouris trout parks improve their fishing success.
RESULTS: Analysis of the first year of information shows that trout caught ranged from 2 to 50 trout per angler and on average was 14 (Table 1). Trout size ranged from 10 inches to larger than 18 inches with the average size of the largest trout caught 14.7 inches. Tippet strength ranged from 2 to 6 pound test and 30% of the anglers used fluorocarbon tippet. Length of tippet and weight of line were not surveyed.
The most successful anglers used woolly buggers, (average catch 30.3 trout per angler); cracklebacks (average catch 13.6 trout per angler); and midge imitations (average catch 12.5 trout per angler). Other lures include rooster tail spinner, dry flies, (Adams, PMD, Renegade, Caddis) glow balls and jigs.
Most anglers fished from the opening bell at 8:00 A.M. until closing of the fishery at 4:00 P.M.with only short breaks for lunch. The most productive time was mid morning (9:00-10:00) and mid afternoon (2:00-3:00).
The best fishing location at Bennett Spring during this baseline survey appears to be Zone 2. For those unfamiliar with Bennett Spring Trout Park, Zone 1 extends from the spring downstream to the dam. Zone 2 from the dam downstream to the Whistle Bridge, Zone 3 from the Whistle Bridge downstream to Niangua River.
In addition to the angling survey, the stomachs of 5 trout were pumped to determine what they were eating. The pumping revealed that only a few small 1-2 mm (1/8 inch) black midges suggesting the success anglers had using cracklebacks and midges may be largely a function of fly size (#18-#22)
During the 2000 outing, water was clear with normal flow of water from the spring. Water temperature was 58 degrees which was consistent with all spring flows in Missouri. Meteorological conditions measured during the day show that humidity was 79%; air temperature ranged from 31 to 43 degrees; the sky was overcast with a 1000 foot ceiling until 3:00 P.M. when the sun broke through the overcast; the barometer was 30.31 inches and falling; upper winds easterly 5 mph. however surface winds because of the configuration of the valley and surrounding hills were from the south. In the evening the moon was full.
DISCUSSION: My survey is a start to what I hope will be a comprehensive data base of fishing information for Ozark Fly Fishers visiting Bennett Spring Trout Park during the catch and release season and should serve equally for those anglers visiting Missouri's other trout parks during the winter season. As I discovered, during this first year, the best flies were, first the woolly bugger, followed closely by the crackleback and midge imitations. The woolly buggers were large (#8 ) and dark. The midge imitations and crackleback flies small (#18 -#22) in a variety of patterns and colors. The crackle-backs were dark yellow or olive with a peacock shell-back and soft brown hen hackle. This fly can be used both as a dry and wet fly. Anglers stripped the crackle-backs just below the surface and fished the midges on light tippets on the surface, in the film and deeper in the water column. The word angler in middle English means "to use bait and wily means."
In his novel A River Runs Through It, Maclean answers a question from his brother about what the trout were feed on "'They are feeding on drowned yellow stone flies.' I asked him 'How did you think that out?.... 'All there is to thinking,' he said, 'is seeing something noticeable which makes you see something you weren't noticing which makes you see something that isn't even visible.' I said to my brother, 'Give me a cigarette and say what you mean.'"
In other words, by observing what is going on around you during a fishing trip, you can better understand what trout are keying on in the stream or physical conditions which affect trout behavior you can become a better angler. Why do fish bite? What causes them to feed or not to feed? Can we develop a mathematical formula such as E=mc2 to explain our fishing success. Will this take away the mystery and fun of fishing or make it more challenging?
We seem to look for aids to help predict our fishing success or lack of success. The Old Farmer's Almanac predicted the best fishing days of the cycle fell on October 27 through November 11; Sports Afield in the November fishing calendar predicted good fishing November 11. Do we fish by these obscure signs, printed in a magazine published in New York or do we base our predictions on the fishing skills of our members and the information gathered during actual fishing trips to Bennett Springs and winter catch and release fishery?
A common perception held by club members is that smaller flies, #16 or smaller work best at Bennett Spring. This initial survey bolsters this perception, although the few anglers using woolly buggers caught more trout on average than did those using small midges or cracklebacks.
Walton in his book The Compleat Angler written in the 1500s suggests the same. "And note that usually the smallest flies are the best; and note also, the light fly does usually make most sport in a dark day and the darkest and least fly in a bright or clear day."
And more recently, Duncan in his book The River Why explains why anglers like numbers, "Like gamblers, baseball fans and television networks, fishermen are enamored of statistics. Statistics are a tool upon which anglers rely so heavily that a fish story lacking in numbers is just that: a Fish Story. A fish without exact weight and length is a nonentity, whereas the sixteen incher or the twelve pounder leaps out of the imagination, splashing the brain with cold spray. The strange implication is numbers are more tangible than flesh; fish without vital statistics are fish without being."
Maybe as this data base grows in the years to come we can put some bones on the cold hard memories has of days fished at Bennett Spring or any of Missouri Trout Parks.
CONCLUSION: The survey will provide the beginnings of a database of fishing information gleaned from our members fishing the winter "Catch and Release" fishery at Bennett Spring. Initially the survey suggests fishing success was quite variable. The best flies are woolly buggers or small dark colored midges or cracklebacks, fished using fine tippets, either slightly under the surface or dead drifted near the bottom. On the average, anglers caught 14 trout per day, with the average size of the largest trout being 15 inches. This survey is a beginning. Further surveys and analysis of the information will be needed to determine which factors are important to fishing success. To quote Walton again: "Oh the gallant fishers life! It is the best of any; 'Tis full of pleasure, void of strife and 'tis beloved by many."
