I was wondering with the water level in the bog rising.
It rose, I covered with more gravel and it rose more. This is without plants. Do you think my pump is pumping too much water under all the rock?
Lowering the water flow may lower the water level. Increasing the outflow area will too.
Plants will raise the level more by blocking flow and as they grow their roots push the gravel up more., which also blocks flow.
The gravel provides resistance and friction against the water. It makes a dam, even though the water can flow through it. This was my big lesson with bogs. The water level at the back of the bog is higher than at the front because of the resistance to flow. Adding rock adds to the resistance the water must flow through. This will raise the water level at the back of the bog even more.
You can increase the flow of the water by channeling out some streams where the rock level is lower so the water can flow faster. This can be done with a stick or hoe or your hands.
