Update:

We dumped 45 tons of lime in the water and it seems to have worked. We bought an old pontoon boat and rented a bobcat and did the liming ourselves. We loaded a scoop of lime at a time and then washed it off the front of the boat with a trash pump. We tried to work a grid pattern to apply it as evenly add possible to the whole lake.

Before liming according to the lake report we were at a pH of 5.5

4 Weeks later i'm happy to report that we are up to 6.5
