General
N.Y. State Public Schools Athletic Association: The site for the largest sanctioning body for high school sports in New York contains tournament schedules (and contact info) as well as the all-important BEDS numbers, which are the enrollment numbers that determine classifications.
Syracuse.com forums: Take a little trash-talking, stir in a dash of gossip and add liberal doses of opinion and you have the sports discussion groups on Syracuse.com, the web site of The Post-Standard. Though the newspaper is a Syracuse publication, topics and contributors are from across N.Y. The football board is always very active, even in the offseason.
Ice hockey
U.S. High School Hockey Organization: The USHSHO does weekly national power rankings for boys ice hockey. One of the more interesting tools on the site is a list of scores from around the country for the last 10 days, which is a valuable resource during the playoffs.
Lacrosse
LaxPower.com: With its daily scores lists, computerized rankings by state (and class) and numerous other bits of imformation, this is one of the better single-sport sites in the country.
Misc.
Official sites of
NYSPHSAA member sections, PSAL and CHSAA.
Multi-sport, section-focused sites
FrontierLeagueSports.com: Covering a sliver of the north end of Section 3 since September 2006.
New York City Sports News: The site covers some college and professional teams, but much of its bandwidth is dedicated to CHSAA and PSAL sports.
SectionV.talksback.com: Launched in January 2007, this site hasn't really hit critical mass yet as it depends chiefly on on message-board postings to deliver content, but it's been improving steadily.
SectionXSports.com: This is one-stop shopping for everything in Section 10, with the "S" staples of information -- schedules, statistics and stories.
National sites
Soccer
National Soccer Coaches Association of America: The NSCAA does weekly national rankings for boys and girls soccer and selects all-region and All-America teams each fall. Such a high percentage of N.Y. high school coaches belongs to the organization the New York is actually a region all by itself in the organization.
Swimming
SwimData.info: It's not a complete list, but there are numerous up-to-date reports on the leaders in individual events and relays from across the state.
Volleyball
RochesterVBall.com: Not just limited to high school volleyball -- or volleyball in Rochester, for that matter. There's some useful information on the site, and the forum boards sometimes get quite active.
Wrestling
Armdrag.com: Largely a Section 5 site, but consistently updated with info of use to fans from around the entire state.
LongIslandWrestling.com: An impressive source of historial information for Sections 8 and 11.
NewYorkWrestlingOnline.com: Regularly updated high school and college news related to New York.
