Last weekend, I spent three days below Carson Pass. We did the Winnemucca Lk trail and back to Woods Lk (the snow field to Round Top Lk and back to Woods Lk didn't interest us). There was still a lot of snow and the creek was pumping. I can only imagine what its like on higher trails. We did have a lot of skeeters, but it was manageable. The sub-alpine is still in early bloom, so it will be in full bloom in a week or so. The alpine bloom will have to wait.

We dayclimbed Mt Baldwin on Sunday. Normally we would start at Convict Lake, but the bridge crosssing was washed out a few years ago. I saw a photo here, I think, showing the creek on July 10 and it looked gnarly. We took a different route, starting at Laurel Lakes Road (4x4/high clearance required). Good decision going that way!

From the Sierra Wave:

"The Mono County Sheriff Search and Rescue (SAR) Team responded on August 7, 2011, to a request for aid to hikers unable to cross Convict Creek. A father was hiking out of the back country with his two teenage children when they became stranded at the trail crossing of Convict Creek due to deep and swift water. The bridge at this site between steep canyon walls was washed out some years ago, and hikers have been required to ford the creek. A hiker on the downstream side of the creek was asked to get help, and he walked out and called the Sheriff’s Department. The SAR Team was dispatched to the area, and 5 team members with swift water rescue gear staged at the Convict Lake Marina. The group was ferried across Convict Lake by boat and hiked toward the stranded party. Prior to arriving at the location, the family was found on the trail, continuing their walk out, having been assisted across by other people in the area. There were no injuries and the group declined any medical treatment."

A brief (and incomplete) history of Convict Creek bridges: A photo essay.

1st image shows the confluence of Convict Creek (running across from right center toward the left) and the outlet stream of Genevieve Lake (forground) in Convict Canyon. No bridge. I had to alter my plans from climbing Red Slate and/or Baldwin and opted instead to follow the stream from Genevieve. I enjoyed a lovely camp at Cloverleaf and traversed the summits of Bloody and Laurel to return to the TH.

I was back two years later in 1984 to climb Baldwin. I was relieved to find a new bridge over the creek, but wait a second...

There seems to be something wrong here...

I'm not 100% sure, but I aways thought this may have been the result of an avalanche. Probably during the previous winter or spring of 1983- one of the heaviest snow packs on record.

Fast forward another year, another trip up Convict Creek. In August, 1985, I found yet another brand new bridge with a very substantial concrete support in the middle.

Okay! This one's gotta last 100 years or more (I thought). Yup, and the feds and the state will never run out of the money to build these things, right? :wink:

South Fork Big Pine Creek

The log bridge about 1.8 miles up the trail was destroyed over the winter by an avalanche. You can cross at the horse crossing 30 feet downstream of the former bridge. The trail splits and short branches lead to either spot. On Labor Day, the creek was about 18 inches deep in the morning and 2 feet in the afternoon. The water force was strong enough that you needed to concentrate to maintain balance. Everyone we saw on the trail had some sort of water shoes or sandals tied to their packs.

Its either high or low. Last year, it was low until the end of the season, then it busted. This year, its sorta the same (late snows). But the flows can't be that high this year as in a normal year. I cant say for sure because I haven't been there and seen it yet.

Why worry about it? Just be cautious and, as usual, and go for it.

Every single year, we have to deal with a different environmental condition. And we generally have a great time.

This is a useful web page. check out the "Snowmelt Runoff Volume Forecasts"

http://cdec.water.ca.gov/rivforecasts.html

Looks like most streams are still rising, with probable peak flows between 5/24 and 6/10. Probable peak flows are the most likely 50% probability; maximum peak flows are 10% probability. A few examples.

Merced at Pohono- probable peak flows at 5/27, maximum peak flows at 6/5
Tuolumne at Don Pedro- probable 5/24 max 6/8
King at Pine Flat- probable 5/29 max6/9
Keweah at Lake Keweah- probable 5/23 max 5/31
Kern at Lake Isabella - probable 5/28 max6/9
Carson at Woodford- probable 5/26 max 6/8

These predictions change daily as new weather data is gathered. Peak flows up in the headwaters will occur earlier by a few days.

Deep layer of dust here haha. Led me to some links I had not seen before. CDEC has a history of changing their web pages frequently.


Also like this page for assessing what is vaguely going on in particular river basins. Numbers at bottom calculate from what has occurred during the month. The % of Historic Averages is a good measure of water conditions. Shows the Kern basin has averaged just 11% of average over May so far with just 283 cubic feet per second down at Isabella reservoir. That says one is likely to find easy spots to ford most everywhere on the main branch. On the other hand the Tuolumne River is much higher at 30% of normal with a current flow of about 1800 cfs because the last few weeks storms have focused in that region.
