Idaho Fish and Game biologists have been monitoring 207 mule deer fawns and 201 elk calves captured earlier in the winter and fitted with telemetry collars.
Through the end of February, 78 percent of the collared fawns and 94 percent of the calves were still alive. That compares with 88 percent of the fawns and 97 percent of the calves surviving through February in 2017-18, and 55 and 80 percent in 2016-17.
While snowpacks and precipitation totals are above average for most of the state, the late arrival of winter weather in 2019 has made for an easier winter for big game than in 2016-17, according to Daryl Meints, State Deer and Elk manager for Fish and Game.
In 2016-17, a prolonged, severe winter resulted in some of the lowest survival rates recorded for mule deer fawns and elk calves. Prior to what was a record-setting February for snowfall for many areas in the state, 2018-19 winter had been a mild-to-average snowfall and temperatures for most of Idaho.
While the weather may be trending warmer so far in March this year, the young animals aren’t “out of the woods” yet. In fact, the March and April are often when fawn and calf mortality is the highest because the young animals’ fat reserves are rapidly depleting and their body’s need time to convert digesting fresh forage.
“April is crucial,” Meints said. “That’s the make-or-break month, when their gas tank is hitting empty. What is going to matter now is how soon winter ends, or how soon spring shows up.”
If the warm weather continues through the end of April, Meints expects fawn survival will fall somewhere in the average range, while calf survival will be above average.
“But if for some reason we get a weather system that is cloudy, cold, and wet, and we don’t get that spring green up on south-facing slopes, we could be in for some additional mortality,” Meints said.
People getting outdoors to recreate in the spring also need to be conscious and considerate of wildlife, particularly big game that remains on low-elevation winter ranges. Despite warmer temperatures and spring green up, deer, elk and pronghorn antelope still need to be left undisturbed to give young animals a better chance of surviving their critical first winter.
F&G Commission sets spring Chinook to open April 27
Limited fishing days on Clearwater, Salmon, and Little Salmon rivers, and the Upper Snake closed
The Idaho Fish and Game Commission approved spring Chinook fishing on the Clearwater, Salmon and Little Salmon rivers during their meeting on Wednesday, March 13 in Boise.
Fishing will open on April 27, with a two-day-a-week season on the Clearwater River and a four-day-a-week season on the Salmon and Little Salmon rivers. The season will run until sport anglers’ shares of the harvest are met (which varies by river) or Aug. 11 — whichever comes sooner.
Due to very low projected returns the Upper Snake River in Hells Canyon, fisheries managers did not propose to open a spring Chinook season for the fishery this year.
Chinook have just started entering the Columbia River and a small portion of them are working their way through Columbia/Snake river systems. Here’s current salmon counts at the dams.
Fisheries managers are forecasting a run of about 32,000 spring Chinook through Lower Granite Dam, which is about 25 miles downstream from Lewiston and the last of the eight dams that returning salmon cross on their way back to Idaho. The forecast is similar to last year’s actual return of 39,000, and below the 10-year average return of 75,000.
Included in the forecast are about 26,000 hatchery Chinook and 6,000 wild Chinook. The 2018 returns were 32,000 and 7,000, respectively, and the 10-year averages are 58,000 and 17,000. Forecasts are a starting point for managing Chinook returns, and they will be adjusted as fish migrate through the river systems.
Because the forecasted Chinook return for the Salmon River basin is about 8,700 fish, and the sport anglers’ share would be 1,430 fish this year. Fishing will be open Thursday through Sunday, with a limit of four total fish, only two of which may be adults.
For the Clearwater River basin, the projected return is about 9,400 adult fish, and the sport anglers’ harvest share would be 470. Fishing will be open on Saturday and Sunday, with a limit of four total fish, only one of which may be an adult.
Just 123 adult fish are projected to return the Upper Snake River in Hells Canyon, where fisheries managers do not expect a sport angler harvest share at all.
“Due to extremely high flows at Hells Canyon in 2017, we had high total dissolved gasses, which are potentially lethal to fish,” aid Jim Fredericks, Fish and Game’s Fisheries Bureau Chief. “In 2017, we chose to release the fish allocated for Hells Canyon at Rapid River instead, to ensure that they survived. For that reason, we have hardly any two-year-old fish coming back to Hells Canyon this year.”
Only hatchery Chinook with a clipped adipose fin may be kept by anglers, and all others must be released unharmed. Chinook anglers are restricted to barbless hooks.
Anglers should refer to the 2019 spring Chinook salmon seasons and rules brochure for other rules and special restrictions, which will be available online in early April, and in paper form prior to the spring Chinook season at Fish and Game offices and license vendors.
The Fish and Game Commission is scheduled to decide on summer Chinook salmon fisheries on the Lochsa River, South Fork Salmon River and upper Salmon River at its May meeting. Fish return to those areas later than to the Clearwater River and Rapid River hatcheries, allowing fishery managers more time to develop season proposals.
