Sniper/esshup, That was a knucklehead post on my part,I should have been more detailed on my thoughts for installation to this point along with some dam specs. My angle is right at a 23 degree slope with a run of 28'(top to bottom of proposed riprap). I'm thinking an 8 or 10 oz. geo fabric, not sure if I want woven or nonwoven. I'll dig a 5" deep trench at the top of the dam to insert the fabric, then backfill. I'd like to run the fabric (stapled) horizontal with a foot overlap in an effort to prevent water channles that I think may happen if I run the fabric vertical (top to bottom) and get some seepage at the overlaid joints. I realize by running the fabric horizontal I'm at risk of getting an accordian effect as the weight may tend to want to slide the fabric. I thought I'd try and prevent that by heavily stapling my fabric. I can get my scag 48" ZTR down it... Just looking to cut some mow time and be a little safer. I have also been thinking about using a PGR (plant growth regulator) before riprap and see how well it will regulate the growth. Mowing it twice or three times a year isn't nearly as bad as all season.The native grass and burn down also sounds like a good idea as well. I have let my fescue grow several inches tall a couple seasons and have noticed several good sized field mice houses when I do a cut in early spring, and dead or very matted grass with water channels already happening. I'd have never thought the mice could effect the dam.I appreciate you guys taking the time"RAPPING" with me. There is my first bad joke as a newbie!! Thanks again guys.
