I took a day trip up to Causey Reservoir which was about 100 miles one way from my home in Tooele, Utah. I packed up my kayak, paddles and gear - a picnic lunch and went driving; made it up to the area and headed to the launch site - which was very much full of people, and kayaks, canoes, etc. I would say over 100 in that small neck area - not feeling safe -because I was by myself, I went back to the "dam" area - and parked there and launched from the side - it was a steep climb down the shale rocks and finally into the smooth water (it was windy) and headed up the other way from the launch area.
There were a few fellow small craft boaters but no motors allowed on this place - which made me happy. I continued up for about 1/2 way to the neck where the river comes into the reservoir and decided to come back it was getting late and there was quite a head wind to paddle against. I stopped halfway back and had lunch - but could not climb or get out of the boat because of the steep embankments this time of year and lower water level.
It was quite peaceful and loved the scenery there - note there is only one bathroom by the launch area and no other facilities close by, but this was a great place to come and I want to go back and make it all the way up to the neck and see the salmon there, there is also fishing at this site - didn't see anything being caught but I saw a few anglers.
one bathroom - nothing else
no fees for entry but if you fish I would make sure you bring your license.
I used the directions provided by paddling.com and got off on 12th street in Ogden, then made a right off the freeway and it was a straight shot up the canyon - only to find Hwy 39 quite a way up and then turned right and headed up to the reservoir, I followed the dirt road up and went to the launch area.
