It's a very rocky bottom on certainly a lot of the lakes. In essence, there's not a lot of silt.
It's interesting. If you talk to the commercial fishermen who are still using nets for their catches, what they've seen is tremendous growth in the amount of algae. It literally blows on the bottom. It fills their nets and it takes forever…. In fact, the Ministry of Natural Resources has been working with them and they're now developing these new nets that will have a space from the bottom up, before the netting actually starts. Algae is becoming more prevalent and it's hurting the industry a lot, so they're trying to adapt their net techniques to get as good a quantity of catch as in the past but not have all the fouling taking place with the algae on the bottom.
