Cannon Air Force Base: Seasonal Potentiometric Surfaces and Groundwater-Level Trends

Declining water levels and a history of high nitrate concentrations in groundwater near and on Cannon Air Force Base (CAFB) necessitated a more detailed assessment of groundwater flow directions than has been done in the past. Previous potentiometric-surface maps were sufficient for showing regional directions of groundwater flow, but more detailed seasonal (summer high-pumping and winter low-...

Evaluating the linkages between regional climate patterns, local climate data, and native Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and non-native brook trout (Salvelinus fontinalis) growth, survival, and life-history expressions.

Beyond large-scale climate models, it is becoming increasingly important to quantify how regional climate patterns link with in situ stream temperatures and hydrologic regimes and concomitantly, fish behavior, growth, and survival. Here, we are using comprehensive mark-recapture techniques to evaluate how changing climatic conditions are likely to influence native westslope cutthroat trout and...
