“…The occurrence of deep lakes is inconsistent in general with the fact that the MWP represented a prolonged warm period known for several extended droughts (e.g., Stine, 1994;MacDonald, 2007;Meko et al, 2007) in the western US. However, periods of enhanced river flow and lake rises are also known for the MWP (Ely et al, 1993;Stine, 1994;Adams, 2003Adams, , 2007.…”

“…Stine's (1994) records for Mono Lake and the Walker River megadroughts brackets the intervening wetter period to wAD 1100-1200 and indicates that drought extended from wAD 1200 to 1350. Records for Walker Lake and Carson Lake (Adams, 2003(Adams, , 2007 are lower resolution and point to high-lake levels between wAD 1035 and 1300. Arizona water division I in northwestern Arizona has reconstructed cool-season precipitation at wAD 1190-1210 as a generally wet period (CLIMAS, 2008).…”

Rene, "Holocene landscape response to seasonality of storms in the Mojave Desert" (2010 Periods of alluvial fan aggradation across the Mojave Desert are 14-9 cal ka and 6-3 cal ka. This timing largely correlates to times of increased sea-surface temperatures in the Gulf of California and enhanced warm-season monsoons. This correlation suggests that sustained alluvial fan aggradation may be driven by intense summer-season storms. These data suggest that the close proximity of the Mojave Desert to the Pacific Ocean and the Gulf of California promotes a partitioning of landscape-process responses to climate forcings that vary with seasonality of the dominant storms. Coolseason Pacific frontal storms cause river flow, ephemeral lakes, and fan incision, whereas periods of intense warm-season storms cause hillslope erosion and alluvial fan aggradation. The proposed landscape-process partitioning has important implications for hazard mitigation given that climate change may increase sea-surface temperatures in the Gulf of California, which indirectly could increase future alluvial fan aggradation.

“…3.12), which was only connected to the rest of the Lahontan system when the lake was at relatively high elevations (>1,310 m). At this location, a Mono Craters tephra can be directly traced from fluvial deposits of the Walker River downstream into shallow lacustrine deposits of Walker Lake over a distance of a few hundred meters (Adams, 2007). The age of charcoal collected from directly beneath the tephra indicates that the lake was rising through an elevation of about 1,252 m around 760 + 40 14 C yr BP (650-780 cal yr BP).…”

“…A group of constructional beach ridges ranging in elevation from about 1,255 to 1,260 m represent late Holocene lake levels at Walker Lake, which are 5-10 m higher than the historical highstand of about 1,250 m (Adams, 2007). The highest of these shorelines (about 1,260 m) date to the neopluvial period around 3700 cal yr BP, when the lake was sill controlled (Adams and others, 2014).…”

Assessing regional hydrologic responses to past climate changes can offer a guide for how water resources might respond to ongoing and future climate change. Here we employed a coupled water balance and lake evaporation model to examine Walker Lake behaviors during the Medieval Climate Anomaly (MCA), a time of documented hydroclimatic extremes. Together, a 14C‐based shoreline elevation chronology, submerged subfossil tree stumps in the West Walker River, and regional paleoproxy evidence indicate a ~50 year pluvial episode that bridged two 140+ year droughts. We developed estimates of MCA climates to examine the transient lake behavior and evaluate watershed responses to climate change. Our findings suggest the importance of decadal climate persistence to elicit large lake‐level fluctuations. We also simulated the current 2012–2015 California‐Nevada drought and found that the current drought exceeds MCA droughts in mean severity but not duration.
