Utah Lake Islands?

[Therapist]

Hey Tin Can, your desire to have the channel at Lincoln Beach is doable, but dredging around Bird Island is a pipe dream. Bird Island is the result of Volcanic activity on the south end of the lake. If you look at the structure of the south end, you will see that the lake bed is a series of steps, about 200-400yds in width and 12-18 inches high. These occurred when magma was pushed out and flowed till it cooled, then another layer was pushed out, one on top of another. You have about 6 of these "layers" till you hit the basin of the lake where the muck begins. Then you have muck till you get to the base of Bird Island, which is a trapezoidal feature of the lake that has extended "arms" off each corner of the island. The Northwest arm is the shortest, less than 50 ft. Northeast is about 150ft, Southeast is the longest, about 400+ft, and the Southwest is about 100ft. To get a visual, draw a rectangle, then push it to one side from the left to the right. Add fingers off each of the corners, with the upper left the shortest, the upper right longer, the lower right the longest, and the lower left between the two on the right. That is the structure of Bird Island. It composed of volcanic rock, like the whole south end of Utah Lake that extends up from the basin muck. It covers less than a square mile without the arms. One of the deepest pockets of the lake is off the Northwest corner, a pocket that is up to 16ft deep depending on the lake level. The island slopes pretty quickly from a high point of about 3-5 ft in low water, down to the basin, which is about 4-6 ft depending on general lake level. The basin then slopes down to about 6-8ft deep and runs to the South shore of the lake where you hit the "ledges/steps" that start in 6-8 FOW and go up from there to the shoreline. Those "arms" of Bird Island are about 3-4 ft in width along their length. That Southeast arm has eaten more props and lower units than I care to count. Again, try and find a copy of the "Utah Lake Monograph", published by BYU Press in the late 60's early 70's. Will show and tell you alot about Utah Lake, it's geology, and other things !!!
