Great tips for sure thank you! I have 3 smaller ravines feeding the main ravine(main part of the lake). My plan was to open up one towards my shallow end and damn it off top have a small pond to catch silt but also(if it works right) to raise fish or bait fish in to re- supply my main lake. My other snack ravines I planned on putting in small wing dams to slow the water down entering my main lake.
