Launching next Monday, April 16th from Sand Island to Mexican Hat on the San Juan with 2 -16 ft catarafts with fishing frames. At what CFS will this become a bad idea? Is 500 CFS too low?

We did Sand Island to the Hat in late March with 3 14 foot rafts and 16 foot cat. There was some hot sandbar action and lots of sleepers that would usually be well below the surface, but it wasn't too bad.

Incidentally, we heard from several BLM folks that there probably wouldn't be a spring release from Navajo at all this year, so you're looking at 470-500 whenever you go for the foreseeable future.

Went in late March from Sand Island to Clay Hills at around 460. The key on the lower at that level, imo, is to not load your boat down with all sorts of things you don't really need, and have your weight evenly distributed. We had one raft on our trip that was dragging in the back and had problems dragging off sand bars. Otherwise, we were fine in 14-foot rafts. --the lack of run-off this year is alarming, but one interesting result is super clear water. Who knew there were so many rocks on the river bed of the San Juan? Super nice float.

Just read this at the following site: Bummer as I have a May 7th permit and was hoping for more water.

https://www.usbr.gov/uc/water/crsp/cs/nvd.html

Under the current soil moisture conditions, snowpack, and inflow forecast for the runoff season, there are no current plans for a spring peak release at Navajo Reservoir.

Releases for the remainder of the runoff season will be made to maintain the minimum target baseflow in the critical habitat reach and will likely range from 300 to 700 cfs.

Just got off, only ran the upper as we opted out of the lower with low flows and high probability of wind. It came up to 790 at launch and was about 1000 when we got off - still was bumper boats through 4 foot and 8 foot rapid. Had a 15', 16' and a dory. River dropping again. It was a good trip but glad I am not on the lower in low water.

Just got home after taking out at Clay Hills yesterday.
River was low but no problems in our 14' Maravia Diablo.
It appears that many people opted out of the lower river: we saw NO rafters below Mexican Hat.
Saw only 3 pack rafters who hiked Honaker and launched there. They floated to Slickhorn and hiked out.
Otherwise, no one on the river or in any camps.
Lots of bighorn, many lambs along the river, where there is the only water and feed.
River was 680 when we put in at Sand Island 5/26.
Last night at Steer Gulch, out from there in two hours. Got out of the raft maybe three times to pull a few yards.

After posting I looked at the Bluff gauge: the river dropped to about 600 the day after we put in, then remained around 9-950 for the duration of our trip.
It has since dropped somewhat.
Apparently the predicted low flows last week were somewhat off, and the river was about 300 cfs higher for that period.

It has been incredibly dry this winter down there. My wife's brother lives north of there in Emery County. We visited him after the trip and discussed the dry winter with him.
I came down through Moab. I was amazed to see how dry the La Sal range was. Last year this time you could have skied up high.
However, I've never seen more wildlife along the river. Turkeys on the upper river, and sheep below Mexican Hat. There was simply no feed or water anywhere outside the river corridor.


Seems like every third ewe was wearing a tracking collar and one or more ear tags. Saw the biggest desert bighorn ram I've ever laid eyes on.

San Juan is projected to be 400-500, is that hi enough to Run?

We're launching from Sand Island this Sunday, September 2 and plan to go to Clay Hills. I spoke to Bureau of Rec. They said flows will likely be between 425-475 cfs to Clay Hills. We have a 14' raft and SUP. Has anyone run it lately? The silt and moss gets heavier in the late summer, so I'm concerned with being able to make it all the way without busting my chops dragging the boat the last 15 miles or so.

Any feedback is appreciated.

THanks

Im trying to not be a smartass, but your post indicates you know exactly how it will go after slickhorn at low levels. For sure youll be dragging your boat. Have fun and hope for minimal wind. 😉
