{"date":"2026-10-19","title":"Mid October: Walker Lane catalog is busier than a typical day","dek":"A daily record of the Truckee basin as of Monday, October 19, 2026. Same honesty rules as Today's Pulse. Forecasts stay labeled.","paragraphs":["It's mid October, and the USGS catalog recorded **5** earthquakes in the region over the last 24 hours, more than a typical day in the last 7 days. The water system keeps its own accounting, from Sierra snow to Pyramid Lake.","There is no Sierra snowpack at the monitoring stations yet this season.","Tahoe sits at 6,226.64 ft, 2.46 ft under the legal ceiling, 3.64 ft above its 6,223 ft natural rim, high enough to spill into the Truckee. Pyramid Lake's USGS surface reading is 3,801.60 ft, the terminus.","Tahoe City outlet 76 cfs; Farad 406 cfs, water 49.3°F; the Truckee at Reno is **in line with typical** for this date, at 90% of the historical median; that 10-year median for this date is 359 cfs against a latest daily 322 cfs; Reno turbidity 60.2 FNU; Farad turbidity not reporting a usable live value. USGS turbidity at Reno jumped to 60.2 FNU from 21.6 FNU on the previous sample.","The four upstream reservoirs hold 58% of listed capacity, Stampede carrying most of that volume.","NWS River Forecast Center outlook, not the USGS gauge: the Truckee at Reno is expected to reach 454 cfs by Thursday, October 22 at 3:00 PM PDT. Source: https://water.noaa.gov/gauges/TRRN2.","Beach postings are a separate clock from the river. Tahoe has a recreational _HAB advisory_ on California's map: Caution at Lake Tahoe Community College (Trout Creek), Caution at Site 13 (Tahoe Keys Lagoons), and Caution at Kings Beach (Lake Tahoe). That posting is a beach warning for swimming and pets, not municipal tap water.","Weather in Reno: 56°F, 0 mph wind.","U.S. Drought Monitor: worst of Reno, Tahoe, and Pyramid Lake is **D1 Moderate Drought**. Reno D1 Moderate Drought; Lake Tahoe D1 Moderate Drought; Pyramid Lake D1 Moderate Drought. That map updates weekly. A late August Drought.gov California-Nevada update noted that evaporative demand can stay high even when water-year precipitation is near normal. Independence Lake: The upper 28 ft is owned and operated by TMWA as Reno–Sparks’s drinking-water drought reserve.","No active NWS warnings or advisories for this basin. That is a reading, not a missing feed.","No uncontained NIFC perimeters in this basin right now.","None of those lake and river numbers is a tap-quality reading. Reno and Sparks drinking water is treated river water. TMWA's published annual mix is 85–95% surface water and about 15% groundwater from 82 wells. Chalk Bluff is the main plant, 90 MGD. This site has no live tap-quality feed. This site has no live well-level feed. TMWA's mix includes about 15% from 82 wells, mainly summer peaks and backup."],"worthWatching":null,"caveat":null,"glance":{"renoPctOfMedian":90},"pulse":["It's mid October, and Tahoe still has a recreational _HAB advisory_ on California's map.","That is a beach warning for swimming and pets.
