Diana shook her head, mouth full. Apparently the consensus was that the North Sea was beyond regulation, but basically stable. They would just have to watch and see what happened, and the seaside towns up there take their chances. Many believed that the North Sea’s level would eventually fall a bit, as water returned to the permafrost or was trapped in one of the thousands of crater lakes in the southern highlands. Then again precipitation and runoff into the North Sea was substantial. The southern highlands were where the issue would be decided, Diana said; she called up a map onto her wristpad screen to show Maya. Watershed construction co-ops were still wandering around installing drainage, running water into highland creeks, reinforcing riverbeds, excavating quicksand, which in some cases revealed the ghost creekbeds of ancient watersheds below the fines; but mostly their new streams had to be based on lava features or fracture canyons, or the occasional short canal. The result was very unlike the venous clarity of Terran watersheds: a confusion of little round lakes, frozen swamps, canyon arroyos, and long straight rivers with abrupt right-angle turns, or sudden disappearances into sinkholes or pipelines. Only the refilled ancient riverbeds looked “right”; everywhere else the terrain looked like a bomb range after a rainstorm.

Many of the Deep Waters veterans who had not directly joined the Hellas Sea Institute had started an associated co-op of their own, which was mapping the groundwater basins around Hellas, measuring the return of water to the aquifers and the underground rivers, figuring out what water could be stored and recovered, and so on. Diana was a member of this co-op, as were many of the people in Maya’s old office. After their lunch Diana went to the rest of the group, and told them about Maya’s return to town; when they heard that Maya was interested in joining them, they offered her a position in the co-op with a reduced joining fee. Pleased at the compliment, she decided to take them up on it.
