Water-level changes impact angler effort in a large lake: implications for climate change

The data set evaluates the relationship between water surface area and angler effort on Devil's Lake, North Dakota. Over the last 30+ years, water levels have expanded/contracted in Devil's laking owing to variation in climate (precipitation). Positive changes (i.e. expansion) in the lake surface area results in increased fish production and angling opportunities that positively influence angler effort and the local economy.
