Onion Valley Reservoir was constructed in the
early 1960s as an irrigation reservoir.
The land surrounding the reservoir is managed by the Bureau of Land
Management making the entire area accessible to angling.
Onion Valley Reservoir covers 101 acres when
full and has a maximum depth of 24 feet.
Sport fish include rainbow trout, bowcutt trout (rainbow x cutthroat trout
hybrid), and tiger trout (brown x brook trout hybrid). Anglers generally catch trout ranging from 9
to 16 inches. The best times of year to fish
are mid-June during the damselfly hatch and from mid-October to the end of the
season (November 15). The standard baits
include nightcrawlers and Power Bait along with flies (nymph patterns and
woolly bugers) fished from float tubes. Camping
occurs at primitive sites and a restroom is located at the south end of the
lake. Aspen stringers make this area a
beautiful place to camp.
A vessel must be operated at a speed that leaves a flat wake, but in no case may a vessel be operated at a speed in excess of 5 nautical miles per hour.
Travel north out of Winnemucca 31 miles, turning left onto SR 140 and on to Denio Junction (100 miles from Winnemucca) before turning left again for another 9 miles. Then turn south onto the Knott Creek Road. Follow the signs to the top of the hill, another 20 miles. Note: Wet spring conditions can make for difficult driving conditions and a four-wheel drive vehicle is usually required to reach the reservoir.
