We have an immediate need for volunteers for some of the following planned projects:

Tributary Flow Surveys No data exists to support potential enhancement of tributaries to make them more accessible for spawners. We have a method to monitor flow rates but need volunteers to go by the river to take some quick, easy measurments from April 30 to mid-June. See some recent pictures of tributaries below.

Main Stem & Tributary Redd Survey A BNF biologist did a thorough redd count in the main river from the dam to Danskin in 2007 and plans to repeat that next month. We have added counting redds in the tributaries for sometime around 5/31 and could use some strong volunteers.

Genetic Study and Fish Sampling Day - July 12 The center piece of the 2008 conservation research will be a genetic study to understand the origins of the fish that make up the South Fork fishery. THe local TU chapter received an Embrace-a-Stream grant to underwrite part of the cost of this project. We are also looking for contributions to sponsor fish and sponsors will get a report back on that fish's genetic history. We will sample fish (non-lethally) from the South Fork Boise below Anderson Dam, and the tissue samples will be used to profile the local rainbow trout population and compare it to an existing library of genetic profiles for wild rainbow trout populations throughout the headwaters of the North, Middle and South Fork of the Boise River. With this data, the biologists can determine where the resident fish originate and then we can determine if spawning enhancements in those location could help the fishery.

The sampling event will be on July 12 and I have proposed that WestFlyer’s make this a “rondi”. We need volunteers to FISH in the name of science or provide driftboats, cooking and shuttles for the weekend event. This looks to be a family event so all are welcome. We can include an informal competition as part of the event as well - should be a really fun day.

Sent: May 20, 2008 7:28 AM Subject: 2008 SFBR Redds

I've completed redd counts from the dam to the bridge below Rock Creek. 232 total redds with 166 between the dam and Danskin Bridge compared to 178 last year. This year at each redd I recorded water depth measurements and will incorporate it into a shapefile at a later time, hopefully this fall/winter. I will also complete a map similar to the 2007 redds in the future. Today is my last day at Mtn Home so be patient and I'll get a shapefile of the 2007 redds, 2008 redds with water depth measurements, and the spawning substrate data I collected last fall to those interested when I can fit it into my schedule.

Thanks,

Clayton Nalder

Late post from my trip to the South Fork on Sunday, June 8 with Chris Jones. We assessed four tributaries and took water measurements. Saw no redds. Saw no gravel that would be good for redds. We did not look too seriously at Granite and Pierce Creeks because we know the crew on the 7th covered those streams.

Cow Creek remains severely impacted by the watershed altering event from 21 years ago (reportedly large thunderstorm and gully washed in August 1987). Lots of rubble everywhere; vegetation has recovered to a degree. Stream bottom is angualr rock and sand.

We checked out about 100 yards Cayuse Creek and of the four I'd say that one may have some potential, but the flow is the least of them, probably 0.5 cfs on June 8.

Meeting with agencies planned for May 18. We'll have some information from the genetics study.

Meeting wan held May 18 on the results of the genetic study and we'll have a meeting in July to present the results and implications of the information.
