Data and code from: Multi-species interactions with artificial causeways in a fragmented lake

Lake Champlain is fragmented by causeways that restrict fish and boat movement between basins, with only small openings for passage. We evaluated potential limitations on cross-basin fish movement using acoustic telemetry data from lake sturgeon (Acipenser fulvescens), lake trout (Salvelinus namaycush), and walleye (Sander vitreus). Crossing frequency at five causeways was determined seasonally, and repeated passage across years was investigated for individual fish. All species were observed in each basin where receivers were present and crossed most or all five causeways; however, no juvenile lake sturgeon were observed crossing causeways. Individuals with greater latitudinal range tended to cross more frequently, with most crossings occurring at two causeways between the Main Lake and smaller basins. Total crossing frequency was similar among species, but seasonal variation reflected species-specific differences in spawning seasons and temperature preferences. Few fish crossed causewa..., , # Data and code from: Multi-species interactions with artificial causeways in a fragmented lake

## Description of the data and file structure

This dataset contains the data and code required to replicate analyses in Futia et al. (in review), evaluating the influence of artificial causeways in Lake Champlain (New York and Vermont) on intra-lake movements of lake sturgeon (*Acipenser fulvescens*), lake trout (*Salvelinus namaycush*), and walleye (*Sander vitreus*). Data include biometric data for fish studied, acoustic telemetry detections for lake trout and walleye, acoustic receiver deployments, a key for tracked fish identified as having died or expelled its transmitter, and corrected data for walleye movements. Lake sturgeon data are not included due to protections as a state endangered species, but these data are available upon reasonable request (contact Lee Simard, Vermont Fish and Wildlife Department, [lee.simard@v...,
