“…Drawdown can accelerate this sediment focusing process (Luken and Bezold 2000), whereby sediment coarsening occurs in the upper littoral zone and fine sediment deposition increases in the sublittoral and the profundal zones (Fig. 2, Hellsten and Riihimäki 1996;Wagner and Falter 2002;Effler and Matthews 2004;Furey et al 2004), potentially leading to shallower lake profiles (Beklioglu et al 2006). Sediment desiccation and erosion from precipitation and wind/wave action consolidate sediment in the drawdown exposure zone (Tarver 1980;Wagner and Falter 2002;Furey et al 2004) and increase sediment bulk density (Gottgens 1994).…”

Conversely, a reduction in drawdown amplitude in an annual drawdown system can promote the deposition of fine sediment back into previously exposed littoral area (Benson and Hudson 1975).…”

“…Reductions in winter drawdown amplitude can increase macrophyte biomass in newly submerged depths. For example, after a reduction in the amplitude of an annual drawdown regime, Wagner and Falter (2002) documented an increase in mean macrophyte biomass at depths shallower than the historical drawdown amplitude.…”

with r-selected life history strategies and with functional traits resistant to direct and indirect drawdown effects. Fish assemblages, though less directly affected by winter drawdowns (except where there is critically low dissolved oxygen), experience negative effects via indirect pathways like decreased food resources and spawning habitat. We identify eight general research gaps to guide future research that could improve our understanding about the complex effects of winter drawdowns on littoral zone ecology.

Annual wintertime water‐level drawdowns are a common management strategy in recreational lakes; however, few studies have estimated their relative impact on lake littoral habitat among a set of typically co‐occurring anthropogenic stressors including lakeshore development and herbicide application. Within 21 Massachusetts, USA lakes that represented a drawdown magnitude gradient (0.07–2.26 m), we assessed depth‐specific littoral habitat (coarse wood, sediment, macrophytes) at two sites adjacent to forested or developed shorelines. Using generalized linear mixed models, we found coarse wood abundance and branching complexity was not correlated with drawdown magnitude but was primarily explained by the presence of lakeshore development. Drawdown magnitude was negatively correlated with silt cover and positively correlated with coarse substrate cover, with effects further varying by depth (0.5 m vs. 1 m). Macrophyte biomass and biovolume were negatively correlated with drawdown magnitude with effects also varying by depth for biomass. Macrophyte taxa with annual longevity strategies (e.g., Najas flexilis) and amphibious growth forms increased in biomass proportions with drawdown magnitude. Distance‐based redundancy analyses suggested macrophyte taxa composition was driven by drawdown magnitude, coarse substrate, alkalinity, water transparency, and herbicide use. These results suggest the importance of water quality and depth on macrophyte assemblage responses to winter drawdowns and the potential to develop drawdown‐tolerant macrophyte assemblages. Altogether, understanding the unique impacts of anthropogenic stressors on littoral zone habitat across heterogeneous environmental lake conditions can help minimize impacts to lake ecological integrity while maintaining recreational value.
