Our predictive models show the range of depth, exposure, and bed slope favorable for SAV in the SLRE information useful for planning shallow-water habitat restoration projects. At more exposed sites, SAV was more likely to occur in shallow areas than at less exposed sites. In one area of the estuary, the probability of SAV occurrence was related to the interaction of depth and exposure. Reduced models, excluding fractal dimension and the lag term, predicted SAV occurrence with 75–82% accuracy based on cross validation and with 68–85% accuracy for an independent SAV dataset collected using a different sampling method. Louis River with 78–86% accuracy based on cross validation of a holdout dataset. Logistic SAV occurrence models including water depth, exposure, bed slope, substrate fractal dimension, lag term, and interactions predicted the occurrence of SAV in three areas of the St. In regression tree models, most of the variation in SAV cover was explained by an autoregression (lag) term, depth, and a measure of exposure based on fetch. Maximum depth of SAV in 2011 was approximately 2.1 m. The dominant SAV species in most areas of the estuary was American wild celery (Vallisneria americana Michx.). The biomass of each species was measured as wet weight expressed in kilogram per square meter (kg/m2). Louis River Estuary (SLRE) of western Lake Superior. From data collected using hydroacoustic survey methods, we created predictive models for SAV in the St. Understanding sources of variation in SAV is necessary for sustainable management of SAV habitat.
