Most angling effort by boats on the main stem of the Clearwater is from Peck to just above the Ahsahka boat ramp. The majority of the shore effort is in the same area but we are seeing an increase in effort by fly anglers from Cherry Lane Ramp to Lenore. Anglers are using orange/pink beads, jigs, or roe. This past week we only interviewed 31 anglers on the North Fork due to survey limitations. However, effort was high on Saturday with over 60 anglers fishing. Most of the anglers that came through the check station were not successful because the fish were just not biting and seemed to be stacking up by the bridge. - Jaime Robertson, Senior Fisheries Technician, Clearwater Region
I was wondering how many hooks you can use for a Alabama rig on Lake pend Oreille. I was wondering if there's any lures you couldn't use on Lake Pend Oreille or any of Idaho
Earlier this week, the Boise River had some water issues. Or no water at all, in places. This was due to an equipment failure at Barber dam.
We've had several concerns about effects to fish in the Boise River due to this.
Our biologists are investigating the issue and have written a description of what they look for to make sure the fish stay happy in the beautiful Boise River.

On Tuesday evening and Wednesday morning, February 3rd and 4th 2015, a series of unfortunate occurrences at east Boise’s Barber Dam (owned by Ada County and operated by Enel Green Power) caused Boise River flows to drop to zero for a period of seven hours.
Maintenance activities are being performed on the dam’s spillway, and to ensure construction crew safety, Barber Pool is being held at less than full pool levels, with all river flows being routed through one turbine. Unfortunately, the gate that allowed water to reach this turbine closed Tuesday night and alarm systems failed. Upstream flows were then caught in Barber Pool, until the point where the pool was refilled and additional water began cresting the dam’s spillway.
During the seven-hour period of zero cubic feet per second river flow over or through Barber Dam, several miles of the Boise River were de-watered or did not receive the “normal” wintertime minimum flow of 240 cubic feet of water per second. Very few people saw the river in this condition as it occurred in the middle of the night. From a fish habitat standpoint, riffles and run habitats were likely severely de-watered, whereas pool habitat likely retained water. Farther downstream areas were less impacted as infiltration of groundwater re-wetted the river channel.
Winter is a critical period for many aquatic species. Dramatic river flow reductions can have negative impacts on aquatic organisms such as fish and invertebrates. Fish survive the winter by reducing activity levels and seeking habitat where they can avoid expending energy while at the same time avoiding predators. This is especially true for young trout. The Boise River possesses wild, spring-spawning rainbow trout and wild, fall-spawning brown trout. Young rainbow trout reside on the river’ edges, usually near downed wood or other cover. A rapid drop in river level may force young rainbow trout to seek alternative cover and become susceptible to predators. It may also cause stranding and death.
For the most part, brown trout spawn throughout the month of November. Boise River water temperatures result in an approximate 60-day brown trout egg incubation period. In early February, young brown trout are just beginning to hatch or have just recently done so. At this critical life stage, water level drops are known to cause brown trout mortality. Other fish species also reside in riffles and near shore areas and may have been affected by the dramatic drop in river flow, including sculpin, dace, and whitefish.
Idaho Fish and Game crews conducted visual surveys of this river segment on Wednesday afternoon, February 4th. No dead adult fish were observed, which was a positive sign. Measurement of potential impacts to young trout and other species are only beginning and will be much more difficult to determine. Crews are at the river today, sampling riffle and river margin areas in the de-watered area and in downstream reaches to make a relative comparison. This should provide some information on possible impacts of the de-watering event.
Other types of suspected impacts may not be readily measured, especially for young trout, non-game fish, or invertebrate numbers and species. Based on the results of these and subsequent surveys, Fish and Game staff will determine whether appropriate mitigation should be pursued from responsible parties.
Who do you recommend for fishing outfitters?
Where are the best spots to fish on lake cascade.
I heard that IDFG was paying a bounty on lake trout in lake Pend O'Reille, but I can't find anything on IDFG's website. Was that a rumor or a discontinued program?
I've heard good things about ice fishing on Mackay reservoir but don't know anything about it. Is it really safe since only half the water freezes over? What kinds of fish are there in the res? What are the best techniques for catching them?
