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

Climate change is expected to influence aquatic habitats and associated fish populations, yet we know little about the impact on recreational anglers. Our goal was to explore whether interannual fluctuations in waterbody surface area and other explanatory variables could be used as indicators of changes in angler fishing effort. Our approach leveraged a combination of remotely sensed waterbody surface area, environmental and fish population data, and onsite angler survey monitoring data for Devils Lake, North Dakota, USA during the open-water fishing period (May 1st to August 31st) for 9 years (1992–2021). The information was used to develop a dynamic waterbody size-angler effort model. Changes in waterbody surface area reliably predicted changes in angler effort (r 2 = 0.60). Increases in waterbody surface area led to increases in angler effort, and decreases in waterbody surface area led to decreases in angler effort. Our findings show promise that remotely sensed fluctuations in waterbody surface area could be used as an indicator of interannual angler effort dynamics. Dynamic waterbody size-angler effort models could provide managers the ability to predict changes in angler effort via climate-related hydrological cycles that affect the size and distribution of waterbodies on the landscape.

Variations in surface-water quality in the chain of lakes and its tributaries, Devils Lake basin, North Dakota, 1957-92

Located in the Devils Lake Basin, North Dakota, receives and stores runoff from the northern section of the basin and recharges Devils Lake. Hydrologic and water- quality conditions can vary greatly in the basin, resulting in potential economic damage. This report describes the seasonal and spatial variations in surface-water quality in the chain of lakes and its tributaries. Long-term trends in dissolved-solids and nutrient concentrations and instantaneous loads in tributaries upstream and downstream of the chain of lakes are not apparent. However,seasonal variations are apparent. Dissolved-solids concentrations were smaller, and nutrient concentrations were larger, during the spring than during the remainder of the year. Variations in dissolved-solids concentrations are caused by dilution and evaporation. Variations in nutrient concentrations are the result of biologic activity. Instantaneous dissolved-solids and nutrient loads were greater during the spring than during the remainder of the year because of seasonal differences in flow rates. Only minimal long-term trends and seasonal variations in dissolved-solids and nutrient concentrations in the chain of lakes are apparent. During the period of record, dissolved-solids concentrations in Sweetwater Lake generally increased, dissolved-solids concentrations in Lake Alice and Lake Irvine varied seasonally, and dissolved phosphorus concentrations in Lake Alice generally increased. Spatial variations in dissolved-solids and nutrient concentrations in the basin are apparent." The medians and ranges of dissolved-solids concentrations for the upstream stations were smaller than those for the lake stations and the downstream stations. Dissolved-solids concentrations were larger in Channel A than in Big Coulee, and nutrient concentrations were larger in Big Coulee than in Channel A.

Late Pleistocene glacial drainage in the Devils Lake Region, North Dakota

The Devils Lake region of northeastern North Dakota is covered with glacial drift deposited by the Leeds lobe of the Mankato Substage of the Wisconsin Stage of the Pleistocene and is underlain by Pierre Shale of Cretaceous age. Associated with the Sheyenne River, which flows through the southern part of the region in a deep trench, are many stream terraces, spillways, deposits of ice-contact stratified drift, and eroded ground-moraine areas. Six stages of drainage have been established to which these various features can be assigned. In the first two stages the features formed as melt water drained to the glacial James River south of the region and as the ice front stood at and later retreated from the site of the Heimdal moraine, a recessional moraine of the Leeds lobe. The later stages occurred after the valley of the Sheyenne River was free of ice and after glacial Lake Souris northwest of the region drained down the valley to glacial Lake Agassiz in the eastern part of the state. Features originating during the four later stages are largely related to the deposition of the North Viking moraine (another, more northern, recessional moraine of the Leeds lobe) and subsequent retreat of the ice from the moraine. Discharge from the local Devils and Stump lakes and from glacial Lake Souris also were of considerable importance in the genesis of many features.

On the postglacial history of the Devils Lake Region, North Dakota

Devils and Stump lakes in eastern North Dakota have been diminishing in area more or less continuously since the land around them was settled in the 1880's. Desiccations similar to the current one have occurred at least once and possibly two or more times in the past and are indicated directly and indirectly by tree stumps recently uncovered as the lake water receded and by lacustrine deposits containing buried soils and vertebrate remains. The lake levels seem to respond in a very sensitive manner to slight climatic changes. Probably the present desiccation and certainly the ones in the past are the result of changes toward a drier and warmer climate. The first may have been synchronous with the Thermal Maximum. A high abandoned strand line and associated lacustrine deposits containing buried soils and vertebrate remains indicate at least one period in the postglacial past, possibly following the Thermal Maximum, that was wetter and cooler than the present. A second desiccation, more definitely established and based on the radiocarbon dating of a tree stump, occurred less than 700 years ago, possibly during the sixteenth century.
