Snowmaking & Grooming


About our Snowmaking System

Since 1966 when Diamond Peak was the first resort in the Tahoe region to invest in a snowmaking system, we've been committed to providing our skiers and snowboarders the best snow surface possible. Thanks to the consistent and pure water supply available courtesy of the IVGID Public Works Department, Diamond Peak's snowmaking system has consistently allowed the resort to enhance what Mother Nature provides and extend the ski season.

New for the 2019-20 ski season, Diamond Peak has purchased four new TechnoAlpin TR8 high-efficiency snowmaking guns designed to produce more snow during all types of snowmaking conditions with less noise. The addition of these new snow guns will allow Diamond Peak to increase the probability of opening the ski area earlier and with top-to-bottom terrain, even during winters in which the resort is reliant on 100% man-made snow during the early season.

TechnoAlpin’s latest design, the TR8 snow gun is designed to require less maintenance and produce more man-made snow per hour, even during marginal snowmaking conditions. The new design of the TR8 snow guns requires just one electric motor to power the entire machine, making the units more reliable, more efficient, and less noisy than previous models of snow guns. The new TR8 snow guns also come equipped with TechoAlpin’s latest ATASSplus software system which optimizes snowmaking based on weather conditions and forecasted snow needs. ATASSplus makes energy-efficient snowmaking much easier, and the software is able to communicate directly with Diamond Peak’s SNOWsat grooming management software (courtesy of Pistenbully), which can provide the snowmaking system with real-time information on snow depths based on Diamond Peak’s snowcat grooming fleet.

The four new TechnoAlpin TR8 snow guns add to Diamond Peak’s snowmaking system of 14 existing snowmaking fan guns, HKD high-efficiency snowmaking towers and compressed air-water snowmaking guns which collectively cover 75% of the developed terrain at Diamond Peak Ski Resort.

HKD SnowmakerSMI Puma Snowmaker
  • Gets the job done at all temperatures with four water flows, hybrid nucleation, and variable airflow
  • Delivers stellar snow quality at high temperatures and big production with minimal air consumption at cold temperatures
  • The modular design of the S-Series allows for technology upgrades and streamlines general maintenance and repair work
  • Equipped with an onboard aspirated weather station, air and water pressure monitoring, and automated flow control
  • Small flow steps deliver a smooth snowmaking curve, fine-tuning the water volume, air pressure, and nucleation to best suit the existing conditions
  • Operators can raise and lower the barrel or adjust the oscillation arc up to 359° on any number of machines from a central command station, delivering pinpoint control with minimal labor. The result is better snow distribution and reduced man-hours needed for grooming
Ratnick Snowmaker- Snow Giant IISMI Super Wizard Snowmaker
  • Able to make snow at warm temperatures
  • Newly redesigned mixing chamber and nozzle sets a new energy standard for internal air/water snow guns
  • Large snow particle size withstands mild temperatures better
  • Best performer for marginal conditions and big throws
  • The Super Wizzard offers a 20HP (15 kW) or 25HP (18 kW) fan and 5 rings of 75 nozzles per ring that can be customized to achieve the water flows specific to our climate
  • These 375 heated nozzles are nucleated with a detachable periphery ring with 20 nucleator nozzles
  • Water adjustment is easy with four heated self-draining valves

About our SNOWsat Technology

Four (out of five) of Diamond Peak's grooming machines are equipped with Pistenbully's SNOWsat snow depth monitoring technology, allowing our grooming operators to see real-time snow depth information on the slopes as they groom, as well as allowing for greater efficiency and seeing where additional snow might be needed to maintain perfect conditions. The SNOWsat system also tracks all aspects of our snow cats' operations, including: run time, gas consumption, GPS tracking on the mountain, and service maintenance.

About our grooming fleet

We currently have five grooming machines, all PistenBully. Three of the machines are the Park Pro models which give us the ability to shape our terrain parks and tricky slope sections better than ever.

According to Mountain Operations Manager Jay Rydd, “The ParkPro is a machine that was designed around the needs of terrain parks, but its enhanced features and ergonomics make every task on the mountain easier. Diamond Peak already had two ParkPro grommers, so adding a third just multiplies what we are able to do every night.”

The new PistenBully 400 ParkPro 4F comes equipped with PistenBully’s newest diesel engine technology, which burns cleaner and allows for more power when needed. The new groomer is also equipped with the PistenBully SNOWsat snow depth monitoring system, which allows the resort’s snow surfaces team to more accurately monitor snow depths on the resort’s developed terrain and see where additional snowmaking might be needed throughout the season, and also allows cat operators to know where more snow might be needed on a run in real time. The SNOWsat system also tracks all aspects of Diamond Peak’s snow cats operations including: run time, gas consumption, GPS tracking on the mountain, and service maintenance.
