Update on the project is that the FHM's did their thing and reproduced. Took about a half of a five gallon bucket worth of 1.5" FHM's (young ones) total out of the mini forage pond over the summer and put them in other ponds. Production should be a lot better next year.
This is a link to the forage pond that kind of goes along with this thread.
Mini forage pond Also have put similar structure in my sediment pond. That thread is located here. It was built later in the year, but still had small FHM fry swimming around earlier this fall so it is working also.
