Chalk Creek consolidates tributaries from the major westerly drainage between Mt. Princeton and Mt. Antero before joining the Arkansas just below Ruby Mountain. Generally having little impact on the volume of water in the river, heavy summer rains on the namesake Chalk Cliffs on the south flank of Mt. Princeton can turn the creek a milky white, impacting visibility throughout the river corridor as the murky water moves downstream. (Fortunately, this only happens a few days a year.) Of greater import is the fishing in the drainage itself, with a fair bit of public water and several campgrounds along County Road 162 west of the Forest Service boundary. Further upstream, beyond the confluence of the North Fork with the mainstem at St. Elmo, trout of greater size are found in the creek, and the tributary Pomeroy, Grizzly, and Hancock Lakes.
