Why aren't they doing this any where up North?
Basically, Stateline Auxiliary is easy to extend, none of the other ones are. The Stateline Auxiliary (Gustaveson) ramp was originally built in the sixties for lake access as it was filling, so the grade is already there, and permitting was simple because they were rehabilitating an existing ramp. The main and spur ramps at Bullfrog don't have enough gradient for launching, the north/exec ramp at Bullfrog is too steep beyond the end and requires a bit of earthmoving, and Halls ends in a steep cliff. Bullfrog Exec has been mentioned for extension to be done by late spring.

So Drewsxmi, this of course leads to yet another question...if predam river, then lake access was Lees ferry, dam building and thereafter Kane Wash (please correct if wrong) At what lake level did Wahweap become viable?

We see it used in '65....but was it first used in late '63, or '64?

Thanks!

During the dam construction there was a "road" through Wahweap Canyon all of the way to the Colorado River, and also the Kane Creek Road which allowed access to the Colorado River near Crossing of the Padres. There is a document discussing boating possibilities in 1963, with mention of the Kane Creek Road getting flooded at one or more of the drainage crossings, and an additional 17 feet of rise needed to get water into Wahweap Basin. Unfortunately the document uses depth at the dam for reference instead of elevation. (I've come to the conclusion that the "depth at the dam" refers to the difference between reservoir level and river level below the dam, not actual water depth in the lake.)

There is a photo of the Stateline Auxiliary Ramp from October, 1964 (estimated date based on water level) with docks and so forth. I'm sure that there was some level of boat access at all times from the beginning of filling. The boating possibilities document also talks about launching from the Kane Creek Road at low points.

As for lake levels, the Stateline Auxiliary Ramp can easily be extended to elevation 3,450', then has a steeper dropoff to 3,423' elevation, which is about the bottom of the Wahweap Basin. At about 3,370' (minimum reserve pool) the water just barely makes it to the current location of the Wahweap Marina.

As always, your sage replies are so appreciated. If anyone has any old photos, would love to see 'em.. (y)

Here's the Stateline Aux ramp in what I believe is October, 1964. The very top of the whale to the right of the ramp has recently broken the surface (around 12/16/2021, about 3,540' elevation). I've been collecting the old pictures that get posted here, and am not claiming credit for being the finder of this one.

LPWD says Oct 1964 was 3491....the entire month....not even moving by more than 1/2 foot. They must have done that for the generators??
