In this case, rain takes grain.

Anphomyces - root rot on the right side of the picture.
No fungicides will control this.
Shows up on hard packed, waterlogged soils, and peas are the worst.
For your crop the disease is spread by surface water plant to plant.
Even if it get hot and dry, what is needed the yield will be determined by if or more likely when the crop lodges, if the plants stay small and shitty with few pods it won't lodge. If the weather and conditions allow for more growth, pods heavier canopy it will lodge and the timing is everything when this happens as it will cut nutrient and water flow to the pods. You will need crop lifters, prepare now.
Impossible to say what yield might result at this time. 10% loss to 50%??

Thanks to those for the constructive input. I suppose I won't know which pathogen it is(for sure) without a lab test. I was in touch with Sask Ag and Food and they said there is nothing I can do about it for any of the pathogens at this stage. I was willing to get the sprayer out but said there is no fungicides that will translocate to the roots. Even had I treated the seed, I was told that it buys me 2-3 weeks of protection and after that they're susceptible again. My neighbor has had a problem for the last 3 years and they treated this year and are still having problems. My pea and lentil days may be over until we get to drier conditions, and was told that Soybeans or Faba beans would work better under these conditions. Pulses have been a valuable part of our rotation. The rotation on that field starting in 2014 and going back when we bought the land is: Peas Durum Flax Canola Peas Wheat Canola Wheat Flax Durum Peas Canola. Now what?

Several years ago soils were saturated, peas looked good early but lodged and turned yellow, burnt and worked down. No tolerance for saturated soil.

If you have enough GDD go for soy. Once they hit third trifoliate they will take a lot of water.

Aggy, I was close to planting some this year but would like to see some shorter season varieties first. According to my research we are on the edge of it making sense. There are some in the area but I think it is still a risky venture here. A lot of ground can still be seen in the fields of soybeans here, I've never looked at the staging but they seem awful small yet.

No crop is waterproof but they seem to recover the best.
