Sounds like a great day of fishing. The lower causeway--you were right to put that into parenthesis, since it appears to be a bridge--is called the Fairfield Road or Fairfield Causeway and is located just north of Mounds State Recreation Area; it splits the upper 2/3 of the lake from the deeper lower 1/3. To tell you the truth I have no idea about the crappie on Brookville, since there are so many fine walleye, white bass and stripers, it is difficult to work up much excitement for crappie on that lake. Others, however, do pursue the crappie. It is my understanding that if you put in at Templeton Ramp (that's inside Mounds Park) or the nearby Garr Hill Ramp, you can boat to the mouth of that inlet and then, being very careful to dodge all the wreckless and inconsiderate d pleasure boaters, you can cross the lake to the Wolf Creek inlet. I think that is a haven for Brookville crappie. If you have a small boat, stay in the Templeton Inlet because there are a lot of stick-ups there that would surely have to hold crappie.
Anyway, good luck and enjoy your time on the water. Play it safe, and if it is after dark, remember to turn off your headlights on the ramp so others can see to back down.
