The fauna of the main stream of Grouse Creek fluctuated more in number and kinds of fish from station to station than did the fauna of Big Caney River. Again, the deep-bodied suckers showed downstream proclivities. In addition, _Notropis buchanani_, _Pimephales tenellus_, _Percina copelandi_, _Percina phoxocephala_, _Notropis percobromus_ and _Pylodictis olivaris_ were taken only at the lowermost station (G-1). At stations G-2 and G-3 the creek is sluggish and often turbid, meandering between high mud banks in a flood plain. At these stations _Fundulus notatus_, _Gambusia affinis, La_-_bidesthes sicculus_, _Ictalurus melas,_ and _Lepomis humilis_ were the most common fishes. Shiners (_Notropis_ spp.) and _Lepomis megalotis_ were rarely taken. Hall (1953:36) states that _Gambusia affinis_, _Fundulus notatus_, and _Labidesthes sicculus_ are usually associated with overflow pools, oxbows, and vegetated backwaters. Those fishes mentioned in the preceding paragraph remained common in the middle section of the stream. In addition _Notropis lutrensis_, _Notropis umbratilis_, and _Lepomis megalotis_ were important members of the fauna. In the uppermost section shiners (_Notropis_ spp.) were common. In the few upstream stations that were still in good condition with clear flowing water, the fauna resembled that of the upstream stations on Big Caney River. Most upstream stations on Grouse Creek were located on highly intermittent streams that are treated below. FAUNAS OF INTERMITTENT STREAMS Because of severe, protracted drought, most of the streams studied had ceased to flow by the close of the survey period. However, the duration of intermittency varied greatly in different streams, as did its effect in terms of the number and sizes of residual pools, water temperatures, pollution, and turbidity. Crab Creek, Beaver Creek, and a small unnamed tributary of Grouse Creek were severely affected by intermittency. Their faunas are discussed below. In Crab Creek six collections were made from points near the mouth to the uppermost pool in which water was found. Pools near the mouth were as large as thirty feet in width and ninety feet in length, while those that were uppermost were shallow puddles averaging ten feet in length and five feet in width. The uppermost station was situated in bluestem pasture without benefit of shade from trees.
