Sunday we took the Anderson Ranch to Prairie to Black Creeks road trip. Took a couple of pictures.
Check out this video from May 6, 2017 showing the South Fork Boise River with water flows running about 7,000 cfs.
The first mile or so of the river is shown in the video, including the drop at the boat ramp that was formed from the debris flows of September 12, 2013.
As of May 10 the flows are now 8,500 cfs. This should be moving some sediment.
Check out this video of rainbow trout spawning in Cow Creek.
Along with the video came this field dispatch:
You can see some smaller fish darting in and out around the female on the nest at 3:48, and again around the last 2 mins. I couldn’t figure out what exactly the smaller fish were doing if they were trying to get in and feed on the eggs, or fertilize the redd or what….
Highlights: redd making at 5:28, 6:32, and 7:43.
I have a few other videos of the other pairs I saw. 4 pairs total with some other males hanging around all in about 100m at the bottom of the grade. I see them in here every year but never this many and never this big.
The video runs a little over ten minutes.
We have a couple of new additions to the library:
- 2015 SFB Juvenile Trout Survey – This report displays the results of the 2015 survey of age zero trout along the stream edges of the South Fork Boise River.
- 2014 SFB Population Survey and Tributary Surveys – This report displays the results of the 2014 population survey. Typically conducted every three years, the survey was accelerated by one year to gauge the effects of the 2013 wildfire and debris flows. The document also contains information on the 2014 survey of tributaries to the South Fork, including some affected by the debris flows in 2013 and 2014.
Thanks to Idaho Fish and Game for making available their annual reports on fishery investigations. We took the large document and extracted the relevant sections so you can review the South Fork Boise River fishery reports and not the rest of southwest Idaho’s waters.
After we take some time to delve into these reports we will come back with a reflection on what it could mean for the South Fork Boise.
WHAT: Riparian Habitat Restoration mitigating effects of Fire on the South Fork Boise with Bitterbrush and Cottonwood planting.
WHO: Interested Fishermen. We will be helping some Youth Groups out of Mtn Home who plan to come with personnel from Mtn Home Ranger District personnel.

After lunch, when the selected sites are completed on the tail water, we will return upstream toward the Dam and without crossing the Dam proceed two miles along the reservoir to Wilson Creek for a second site.
