Fishes of Chautauqua, Cowley and Elk Counties, Kansas — Inside the Classic

Stream Systems and Collecting Stations

Metcalf divides the survey area into three general topographic sections and describes the physical characteristics of the streams. The collecting stations are coded by river system (e.g., A for Arkansas, W for Walnut, G for Grouse, C for Caney), and each species account lists the stations where it was taken. For instance, the black bullhead (Ictalurus melas) was recorded at 33 stations, spanning multiple systems, while the yellow bullhead (Ictalurus natalis) appeared at only 9, mostly in Grouse Creek. This station-by-station approach allows Metcalf to map distribution with precision, noting where species are abundant, scarce, or absent. The data reveal that certain species, like the plains killifish (Fundulus kansae), are confined to lower parts of the Walnut River, especially where petroleum pollution is evident, while others, such as the black-banded topminnow (Fundulus notatus), show sharp drops in relative abundance beyond a five-mile stretch of Grouse Creek.

Habitat Preferences and Intermittency Effects

Metcalf's analysis of habitat preferences is grounded in physical conditions. The mosquitofish (Gambusia affinis) was taken at every station in the Arkansas, Walnut, and Grouse systems except upland tributaries, and it was absent from clear upland tributaries of Big Caney in spring and summer, appearing only in September. The black bullhead thrived in silty bottoms and isolated pools, especially in intermittent streams like the upper ends of Crab Creek, Beaver Creek, and Grand Summit Creek. In contrast, the flathead catfish (Pylodictis olivaris) and channel catfish (Ictalurus punctatus) were collected only in larger streams, often by angling. Metcalf explicitly lists “demonstrable effects of intermittency of streams on fish distribution” as one of his aims, and the data show that species like Gambusia and I. melas dominate shallow, isolated pools in late summer, while others are excluded.

East-West Distribution Patterns

A key objective is relating findings to the east-west distribution of fishes in Kansas. Metcalf notes that Fundulus kansae has not been taken eastward from the Walnut River, while Fundulus notatus was common in the Walnut and Grouse systems but absent from the Arkansas River. The black-banded topminnow did not ascend far into smaller tributaries of Grouse Creek, and its highest relative numbers occurred within a five-mile section of Crab Creek and Grouse Creek, dropping off sharply upstream and downstream. These patterns suggest that stream order, turbidity, and substrate—rubble and mud at the high-abundance stations—play a role. Metcalf also compares faunas of different streams, noting that the Grouse Creek system yielded more black bullheads than any other, and that Big Caney River had few I. melas in its main stream but many in tributaries.

Readers should approach this work as a primary scientific document from 1959, rich in raw data but limited in interpretive synthesis. The excerpts provide a window into Metcalf's methodology—station codes, species lists, and habitat notes—but the full report includes additional tables and figures that may clarify faunal comparisons. Pay attention to the interplay between stream permanence and species occurrence, as this is a recurring theme. The work is best used as a reference for historical fish distribution in south-central Kansas, offering a baseline for studies of environmental change.

There’s something tender about Metcalf’s careful lists of where each fish was found, knowing some streams have since gone dry. That same quiet patience lives in the fossil record, too—a glimpse of an ancient coelacanth, waiting in stone. I keep thinking about how both books honor what remains, gently. A New Genus of Pennsylvanian Fish (Crossopterygii, Coelacanthiformes) from Kansas — Reading Companion feels like a hand reached across deep time.
