This is current situation
And this is plan
That smaller pond will be shallow bog, connected on same level with semi deep canal and deep pond with a slope going deeper (5ft) away from house. That wood deck will be about 2-3 feet over the pond for hiding equipment. That deck closer to house will be with bricks and theres 2-3 steps for going to lower lever (brick deck will be higher). For privacy screen ill use Virginiana 'Skyrocket'. Its narrow and tall.
For the fauna ill want some kois and maybe some regular goldies and for plants irises, water lily, cyperus papyrus and such. Filtration i intend to use the lower the possible with light fish load. Filtration pit will probaby be below that wood deck.
Pond and bog will have concrete collar with red bricks for paving and dont know yet for that walk... Maybe bricks too, will see
