This is the last Bay Journal before our annual summer break, so we've packed this oversized 36-page issue with all sorts of articles to hold your interest until the September issue arrives.

Lara Lutz and Dave Harp proved that Bay Journal staffers will go to any depth — literally — to get the story. They crawled through caves, both "wild" ones and tourist ones, to explain the impact that karst geology, which underlies many sections of the Bay watershed, can have on water quality and water supply.

Rona Kobell also took a journey underground to explore the maze of buried streams that underlie urban areas and make up significant portions of watersheds that feed the Anacostia River, Baltimore Harbor and other urban waterways. Though out of sight to most people, there is hope that some of these streams will once again see the light of day.

Meanwhile, some streams that are open to the sun may become closed to the public. Beau Beasely explores concerns about Crown Grants, which may be used to restrict access to some of the region's most prized waterways.

Otherwise, you'll find articles about the sex lives of crabs; hope for shad; updates on Watershed Implementation Plans; Amish farmers helping cleanup efforts; and quizzes on one of the Chesapeake's more unusual creatures, the lined seahorse — something for just about everyone.

We have five pages of activities listed in an expanded Bulletin Board section, so nearly everyone can find a volunteer, educational or recreational activity to participate in during the summer.

So catch up on reading, enjoy the summer, and look for us in September.

Midday on the Bay

Also during the summer, you can keep up with our radio program, Midday on the Bay, produced in partnership with WYPR in Baltimore, in which staffer Rona Kobell discusses issues facing the Bay. The program broadcasts the third Thursday of every month. Tune in Thursday, July 19 and Thursday, Aug. 16. Topics usually dovetail with stories covered in the Bay Journal.

WYPR  broadcasts in Baltimore, Salisbury, Ocean City and Frederick. Those outside the listening area can catch the program online, either live or archived, at www.wypr.org/Midday

Bay Journeys was a hit!

The inaugural issue of our new travel paper, Bay Journeys, was a hit. Not only were they included in the June Bay Journal, we also printed an additional 10,000 stand-alone copies for distribution. They were gone so fast we had to do an additional press run!

If you operate a tourist-related facility or other location where travelers pass through and you would like to put Bay Journeys on display, let us know and we'll send you a bundle while they last. Contact me at 717-428-2819, or e-mail requests to kblankenship@bayjournal.com.

The next issue is in production. Look for it soon.

Meanwhile, if you are interested in advertising information for the next Bay Journeys, e-mail advertise@bayjournal.com, for information. Or, in Southern Maryland, contact account executive Diane Burr at BaysidePartners@gmail.com or 410-231-0140.
